The cargo hold of a passenger aircraft is loaded with tons of passenger baggage and cargo that needs to be loaded and unloaded in a short period of time. The real challenge of loading and unloading cargo on an aircraft lies in the time constraints.Aircraft can only make a profit when they are in the air, so airlines do not want their aircraft to stay on the ground. Once the aircraft lands, preparations for the next flight begin. These preparations include unloading all the baggage and cargo from the arriving flight and loading new cargo for the departing flight. Specialized equipment and well-coordinated teamwork ensure that this task does not delay the aircraft's takeoff.In this article, we will learn about the loading and unloading of baggage and cargo at the airport, focusing on understanding the ground support equipment involved in the process.Baggage transportation from airport lounges to parking positionsAirports have complex conveyor belt systems that receive passengers' baggage from the check-in counters in the airport lounge and transport it to different parts of the airport. In large airports, the entire conveyor belt network can be several kilometers long. It all starts when you check in your baggage at the check-in counter in the airport lounge.The check-in counter staff loads your baggage onto the check-in conveyor belt, which in turn delivers it to a series of conveyors that eventually deliver it to the baggage conveyor belt, where it is arranged for further processing by airline staff. At this point, the baggage is still inside the airport building. Airline staff manually transfer all the baggage from the baggage conveyor belt to a baggage cart or unit load device (ULD), which we will explain later in this article. For now, let's first learn about baggage carts. Ground staff load multiple baggage carts with baggage and connect them together to form a train of baggage carts to tow to the aircraft. At this point, the baggage is ready to leave the airport building.Tow trucks are used to tow baggage carts from the airport building to the parking stand where the aircraft is parked or to the restricted area of the hangar. For large passenger aircraft such as the Boeing 777 or 747, the tow truck may need to make multiple turns to transport a full baggage. At this point, the baggage is in the open-air cabin, beyond the airport building, ready to be loaded into the aircraft cargo hold.Airport Belt LoaderOnce the baggage carts have arrived at the parking stand, it is time to load the baggage into the aircraft cargo hold. The problem is that the aircraft cargo door is several feet off the ground, so it is not possible to load the baggage into the hold manually. There is a specialized ground support equipment called a belt loader that can be used to do this job.A airport belt loader is simply a mobile conveyor belt. The conveyor belt is mounted on a boom whose inclination can be adjusted to suit the height of the aircraft cargo hold.The conveyor belt is driven by a motor that rotates in both directions to enable loading and unloading. Rubber bumpers are provided at the end of the boom to prevent any scratches or indentations to the aircraft body when the conveyor loader comes into contact with it. The entire system is mounted on a truck chassis for easy movement.The operation is simple. The belt loader conveyor belt is started by pressing the forward button on the cargo loader control panel for loading. One or two team members unload the baggage from the baggage cart and manually load it onto the conveyor belt. The baggage moves up the incline and does not slide off due to the friction between the baggage and the conveyor belt fabric. The operator who is already waiting in the aircraft cargo hold receives the baggage and organizes it into the cargo hold. In this way, man and machine work together to load the baggage into the cargo hold.Unit Load Devices (ULDs) and Cargo TrolleysAn alternative to baggage trolleys is the use of a unit load device (ULD). It is a standardized container used to store baggage or cargo in an aircraft. The dimensions and sizes of ULDs are standardized, and a specific type of ULD is suitable for a specific type of aircraft. The dimensions and sizes depend on the cargo hold design of the aircraft type that the ULD is compatible with. The main advantage of using a ULD is that it saves time. Baggage is bundled into fewer handling units, making loading and unloading easier.In addition, organizing baggage in the cargo hold is made easier as there is no need for manual sorting. ULDs are designed so that they can slide and fit in the cargo hold and are equipped with corresponding devices to ensure that they are firmly fixed to the cargo hold surface during flight to prevent them from moving or getting out of place.Unit Load Devices (ULDs) are not only used to transport baggage, but also other cargo, such as mail and spare parts packages. It is not difficult to understand how a unit load device (ULD) simplifies the handling of baggage and cargo. Instead of unloading luggage from the airport baggage carousel onto a baggage trolley, staff load the luggage into a unit load device (ULD).These ULD containers are placed on cargo dollies, which are special carts designed to carry ULDs and transfer them to the cabin using a tractor, just like a baggage dollie.Cargo trailers are specially engineered to carry unit load devices (ULDs). The trailers are equipped with rollers to prevent the ULDs from being scratched when the crew pushes and pulls them on the cargo trailer. In addition, the trailers have built-in locks that lock the ends of the ULDs to prevent them from sliding on the cargo trailer and falling when the tractor turns.Cargo LoaderOnce the ULDs are transported to the aircraft parking area with the help of the tractor, the ULDs are loaded into the aircraft cargo hold by a special machine called a cargo loader, as belt loaders are not designed to load ULDs. Like many other ground support equipment, the entire system of the cargo loader is built on a truck chassis and can be driven to the desired aircraft parking position for operation.It has two platforms. The frontmost platform is called the bridge, as it acts as a bridge between the aircraft cargo hold and the loading platform. The bridge is mounted on a scissor lift so that its height can be adjusted to the height of the aircraft door.The operating panel of the cargo loader is also located on the bridge and is used to control the height movement as well as drive the truck. Loading platform This is where the ground staff load all the ULDs from the cargo trailers. The platform is also mounted on a scissor lift mechanism that can be raised and lowered independently of the bridge.Once the ground staff loads the ULDs onto the platform, the operator raises the platform to the same height as the bridge, which in turn is the same height as the aircraft door. This way, all three platforms are at the same level and the system is set up for transferring ULDs and cargo packages in the aircraft cargo hold.Cargo and baggage handling for arriving and connecting flightsWhen unloading cargo and baggage, the entire process is reversed. The cargo loader unloads the cargo; the belt loader unloads the baggage; and the staff loads the baggage carts or ULDs onto the cargo trailers on the apron and tows them to the airport building.Cargo trailers loaded with ULDs and baggage carts loaded with baggage are transported from the aircraft to the airport building, where staff unload the baggage via the baggage claim belt, from where passengers can collect their baggage.Similarly, in connecting flights, baggage and cargo are not transferred directly to the airport, but to another aircraft. This is why time is of the essence in cargo and baggage handling. Any delays will directly affect the flight schedule and cause dissatisfaction among passengers.

What is Aircraft ULD in Air Transport?If you’re shipping air freight, your main concern is getting the freight where it needs to be, and fast. When you ship cargo by air, you’re most likely using a ULD (Unit Load Device), but what is it? An aircraft ULD is a piece of equipment used to group and restrain cargo, mail, and baggage for air shipment. It can be either an aircraft container or a combination of an aircraft pallet and an aircraft pallet net.In this article we’ll answer some basic questions about what goes on behind the scenes as air cargo moves from your dock to your customer.What is a ULD?Building Airline ULDA unit loading device (ULD) is the air freight equivalent of the ocean container. It allows for the safe, fast, efficient transit of freight on passenger and cargo aircraft. A steamship line can put upwards of 20,000 stacked containers on one vessel. With airplanes, it’s a different story. Loading spaces are small and irregularly shaped. That’s why there are many different ULDs, in different sizes and shapes, to make the best use of the available space.There are two basic types of ULD: a closed metal container that houses freight inside and a metal pallet onto which cargo can be loaded. Cargo on pallets is covered with a net and secured under the ULD. Whether you’re moving pallets of merchandise or cars or expensive equipment, ULDs are secured to the body of the aircraft to keep the freight from shifting, even during the most turbulent flights.Air cargo can be tendered to the carrier either loose or already containerized. Once loose freight is checked in, it is loaded by the carrier into a ULD.Why Airlines Need ULDs？Fast global shipping means air freight. Every 24 hours, more than 140,000 tons of cargo are transported, equivalent to 657 million packages worth $17.8 billion. To transport this much air cargo, a large number of aircraft ULDs are needed to safely deliver the cargo from one destination to another. Many multinational companies utilize air freight and unit load equipment to move perishable items such as fruits and vegetables, seafood, flowers, time and temperature sensitive healthcare products such as vaccines and other pharmaceuticals, not to mention air mail services provided by postal operators around the world for letters and express parcels, and many more items that need to be delivered quickly and safely.What types of ULD equipment do airlines have?1. Air Freight ContainersContainers are closed equipment used to carry cargo or luggage. Containers come in different sizes and shapes depending on the type of aircraft and airline requirements. Common container types include:● LD3 (or ULD Type A): A common wide-body aircraft container, typically measuring 1.53m x 1.57m x 1.63m (length x width x height). This container is mainly used on aircraft such as Boeing 747 and Airbus A330.● LD6 (or ULD Type D): A larger container, measuring 2.13m x 1.58m x 1.53m. Usually used on Boeing 767 or similar aircraft.● LD7 (or ULD Type G): Used on larger aircraft such as Airbus A380. The dimensions are 2.47m x 1.58m x 1.53m.● LD9 (or ULD Type P): For large aircraft or wide-body aircraft, the dimensions are 2.51m x 1.58m x 1.53m.2. Aircraft PalletsPallets are open ULD devices, and the cargo is placed directly on the pallet, usually fixed by straps, grids or other fixings. Common pallet types include:● P1P (or Type 1): The standard size is 2.44m x 2.44m, suitable for large aircraft such as Boeing 747 and Airbus A300.● P2P (or Type 2): A smaller pallet with a size of 2.44m x 1.88m. This pallet is usually used in smaller aircraft or cabin areas.● AAY (or Type A): The size is 2.19m x 2.44m, suitable for multiple models, especially some models of Airbus and Boeing.When would you use a container or a pallet?Airline Containers have the following advantages:● Make loading and unloading faster and easier● Protect against any kind of weather – do not require the extra wrapping that you’d want for the palleted cargo● Protect better against damage ­– no need for corner guards or other special protective packaging● Prevent unauthorized access to the cargoWhen to use a container- Makes loading and unloading cargo easier- Makes loading onto and unloading off an aircraft easier- Gives better protection against all kinds of weather- Gives better protection against damage to the cargo- Gives better protection against damage to the aircraft by the cargo- Prevents unauthorised access to the cargoULD pallets, sometimes referred to in the industry as “cookie sheets,” are cheaper to use than containers. Other advantages:● Accept oversized cargo that won’t fit in a container● Take up less room than containers since they are flat and can be stored efficiently and returned by plane● Have more options for how to build the pallet (size and shape) depending on where on the plane the airline ULD pallet is being loadedWhen to use a airline pallet/net- Cheaper to use than containers- Accepts cargo that is difficult to fit into containers (e.g. oversized cargo)- Accepts some ‘Special Load’ cargo that can only be loaded on pallets- Stackable: efficient and easy to store and returnAs a shipper, the choice of ULD is typically made for you, by the airline or your freight forwarder. It’s a little different if you’re shipping temperature-sensitive cargo. You’ll want a specialized, temperature-controlled airline ULD.What factors should you consider when choosing an ULD?Aircraft Containers are ideal for high-value or sensitive cargo, while pallets are suitable for oversized or bulk items. AirlineContainers offer better protection for long-distance shipments, while pallets may be more cost-effective for shorter distances.Temperature-sensitive cargo may require specialized containers or ULDs with temperature-controlled features.How to Load / Unload of Aircraft Containers1.Always check the unit before starting loading. Any damage found must be below the required damage limits otherwise the ULD is not airworthy.2.Cargo or bags should be stacked in an interlocking fashion as far as possible.3.Avoid placing heavy cargo in the outboard section of the container (overhanging section) as this can cause the container to rock or tilt to the outside, causing loading difficulties.4.Ensure that cargo/ baggage in the door side does not extend to the point that the door is not flat when closed.5.Inspect the loaded ULD to ensure it is within the designated contour. It may appear that a container is within its contour by the nature of its structure, however there are extremely small clearances between the container and the cargo hold liner in many aircraft and even a small distortion in the container structure (as may occur due to certain types of damage, or from loading heavy cargo in the overhanging section of the container) can result in the container touching the hold walls, causing considerable damage and grounding the aircraft (hold liners are fire containment devices and if punctured the aircraft cannot take off). Care must be taken that all ULD are within their designated contour before they are loaded to the aircraft.6.Consult airline guidance for any heavy items which may require spreader boards to spread the weight on the base and may require additional tie down using cargo straps.7.When closing the door, do not use hammers or other excessive force to operate latches etc as these will almost certainly not be openable on arrival at destination.8.Never use knives to cut open a container doorHow to Load/unload of Aircraft Pallets/nets1.Before loading begins, perform a pre-loading inspection to determine if the pallet and nets are serviceable. Particular attention should be paid to cargo nets used to secure cargo to the pallet. Cargo nets are subject to severe wear and tear and are often unusable. It is important to determine if the nets are serviceable before loading the pallet.2.Load cargo in an interlocking manner whenever possible. Ensure that the cargo is within the specified profile. Overhang cargo (for lower deck cargo) must be constructed in such a way that the overhang will not collapse in flight.After all cargo is loaded, the net should be used as follows:● Place the net over the load and attach the net accessories to the seat rails evenly spaced along both sides● Use the "reefing hooks" on each side to retract excess net (found in non-full profile loads)● Close and gently tighten the net using corner ropes (lashing wires) or other suitable corner closure devices.Note: While it is generally accepted in the industry that nets need to be as tight as possible, this is incorrect. Neither manufacturers, aviation safety agencies nor IATA have made such a requirement. The correct approach is for the net to be tight but not too tight. The purpose of the net is to limit forces during flight, and it performs this function perfectly when installed without tension.1. Over-tightening the net can not only damage the cargo, but can also pull up the pallet edge rails, making it difficult or impossible to lock the pallet to the aircraft.2. Freight often needs to travel considerable distances by road to the nearest airport, so it has become common practice to use cargo nets as "fixtures" to secure cargo during road transport. The design of the cargo net (diamond mesh) is not suitable for this purpose.3. Never use a knife to cut the net. This will damage an expensive airline asset and render the net unusable.How to Identify ULDs by CodeEach aircraft unit load device (ULD) is identified by its ULD code. This code is a unique combination of letters and numbers that begins with a three-letter prefix that identifies the type of ULD. This prefix is followed by a unique 4- or 5-digit serial number to distinguish it from other devices of the same type. The last two or three characters indicate the owner of the ULD.How do airline ULDs and ULD manufacturers affect your ability to ensure reliable air freight capacity?Passenger airlines often overbook and then have to ask some passengers to get off the plane and take a later flight. The same is true for air cargo! Especially in the current market where cargo capacity is limited. If you work with a freight forwarder that has a Bulk Service Agreement (BSA) with the airline, your cargo is less likely to be unloaded. Large freight forwarders essentially pre-purchase cargo space from airlines before they have customers. These BSAs correspond to a certain amount of cargo (metric tons) on a specific route at a specific time. Most of the committed tonnage is usually achieved through fully assembled ULDs. So if your cargo is transported by a freight forwarder who assembles the ULDs and gives them to the airline, the space is fixed. On the other hand, if the cargo is given to the airline in bulk, the airline assembles the ULDs, mixing your cargo with that of other freight forwarders. In this case, the airline is not obligated to transport this cargo on a specific flight as part of any existing BSA. So if the carrier accepts more cargo than it can carry, it can unload your cargo.Cheerong Aircraft Container & Aircraft PalletAirfreight Containers (ULD) is a type of pallet or container used to store bulk cargo for transport by air.

They're also resistant to corrosion, ensuring longevity even in harsh conditions like humidity or exposure to de-icing agents.● Wheel Power: Wheels are arguably the most critical component of a trolley. They endure constant rolling, turning, and impact. Choose trolleys with rubber or polyurethane wheels that can withstand heavy weights, resist wear and tear, and provide a smooth, quiet ride for passengers. Don't forget about the wheel bearings! Sealed bearings require less maintenance and offer smoother operation, contributing to the trolley's overall lifespan.● Construction Quality: A Deeper Dive: Go beyond the surface and examine the trolley's construction quality. Look for reinforced joints, strong welds, and a sturdy frame. A well-constructed trolley will hold up better over time, reducing repair and replacement costs. Pay attention to details like the handle design and basket construction – these areas should be robust enough to withstand frequent use.● Battling the Elements: Airport environments can be harsh, with exposure to moisture, cleaning agents, and temperature fluctuations. Choose trolleys with corrosion-resistant coatings or materials that can withstand these challenges. Consider features like galvanized steel or powder-coated finishes for added protection.● Maintenance Made Easy: Consider the trolley's maintenance needs. Some trolleys have easily replaceable parts, such as wheels, handles, and baskets, which can simplify maintenance and extend their lifespan. Look for trolleys with modular designs that allow for easy component replacement, reducing downtime and repair costs.Passenger-Centric Design: Catering To Diverse NeedsAirport trolleys should be more than just functional; they should cater to the diverse needs of all passengers. A well-chosen trolley fleet can significantly improve the passenger experience, making their journey through the airport smoother and more enjoyable.Here's how to choose trolleys with passenger needs in mind:● Size and Capacity: One size doesn't fit all. Offer a variety of trolley sizes to accommodate different luggage types and passenger needs. Consider compact trolleys for single travelers and larger ones for families or those with bulky luggage. Don't forget about specialized trolleys for oversized items like skis, strollers, or musical instruments.● Accessibility is Key: Ensure your trolley fleet includes options for passengers with disabilities. This might include trolleys with lower handles for wheelchair users or those with limited reach. Consider trolleys with wider bases for added stability and those with braked wheels for secure maneuvering.● Comfort and Ease of Use: Look for trolleys with features that enhance passenger comfort. Ergonomic handles, smooth-rolling wheels, and easy-to-maneuver designs can make a big difference. Consider trolleys with features like cup holders or compartments for small personal items to add convenience.● Child-Friendly Features: For families traveling with young children, trolleys with child seats or safety straps can provide peace of mind and improve the overall travel experience.

The efficiency of modern aviation relies heavily on a hidden workforce: Ground Support Equipment. These specialized vehicles and machines are essential to the safe and timely operation of aircraft, ensuring everything from passenger comfort to cargo loading is handled with precision. In this blog post, we'll take a closer look at the critical role GSE plays in keeping the aviation industry running smoothly.What Exactly Is Ground Support Equipment?Ground Support Equipment, or GSE, is a broad term encompassing the machinery and equipment that helps aircraft operate safely and efficiently while on the ground. Think of it as the unsung hero of aviation, working tirelessly behind the scenes at airports and airfields worldwide. From the moment an aircraft touches down to when it takes off again, GSE is there to support every step of the process. It's the lifeblood of ground operations, ensuring smooth transitions between flights and maximizing turnaround time.But GSE isn't just about moving aircraft. It's a diverse collection of specialized equipment with functions ranging from powering the aircraft (think Ground Power Units or GPUs) to servicing lavatories (with toilet carts and potable water trucks). Imagine the complexity of preparing an aircraft for departure - GSE provides the necessary air conditioning and electrical power while the plane is parked at the gate, refuels the aircraft, and loads baggage and cargo. Simultaneously, other GSEs might be de-icing the plane, providing stair access for passengers, and even catering meals.GSE also plays a vital role in passenger comfort and cargo operations. Passenger boarding bridges, those iconic walkways that connect the terminal to the plane, are a prime example of GSE. They allow for safe and convenient boarding and disembarking, especially in inclement weather. And let's not forget the conveyor belts that efficiently transport luggage from check-in to the aircraft and vice versa, minimizing delays and ensuring a smooth travel experience for passengers and crew alike.Types & Various Uses Of Ground Support EquipmentGSE can be broadly categorized by its functionality, allowing ground crews and aviation professionals to quickly identify and utilize the right equipment for specific tasks. Let's explore some of the most common types in more detail:● Aircraft Tractors and Pushback Tugs: These aren't your average tow trucks! These powerful vehicles are specifically designed to maneuver aircraft with precision, particularly in the tight confines of airport gates and taxiways. Pushback tugs, with their unique design and low profile, are used to safely push the aircraft away from the gate, initiating the departure process. Think of them as the 'muscle' behind aircraft movement on the ground, ensuring safe and efficient maneuvering.● Ground Power Units (GPUs): Essential for minimizing noise and emissions, GPUs are the silent workhorses that supply aircraft with electrical power while their engines are off. This ensures that vital systems like cabin lighting, air conditioning, and critical avionics remain operational without the need to run the aircraft's engines, contributing to a more sustainable airport environment. Modern GPUs come in various sizes and power outputs to accommodate different aircraft types, from small regional jets to large wide-body airliners.● Air Start Units (ASUs): Ever wondered how those massive jet engines roar to life? ASUs provide the answer. These units deliver high-pressure air to start aircraft engines, much like a jump-start for your car but on a much grander scale. They are particularly crucial for larger aircraft with powerful engines that require a significant surge of airflow to initiate rotation. ASUs can be either diesel-powered or utilize compressed air stored in tanks, offering flexibility in different operational environments.● Passenger Boarding Bridges: Say goodbye to those exposed stairways and hello to comfortable, climate-controlled boarding! Passenger boarding bridges, also known as jet bridges or airbridges, are those iconic enclosed walkways that connect the aircraft door directly to the airport terminal gate. They provide a seamless and protected passage for passengers, shielding them from the elements and ensuring a comfortable boarding and disembarking experience, especially in inclement weather or extreme temperatures.● Baggage and Cargo Loaders: Behind the scenes of every flight lies a complex dance of baggage handling. From conveyor belts that whisk your luggage away at check-in to specialized vehicles with lifting capabilities, these loaders ensure the efficient and timely transfer of passenger bags and cargo to and from the aircraft. This intricate system minimizes turnaround time, keeps baggage moving smoothly, and plays a crucial role in on-time departures.● Refuelers: Keeping those aircraft fueled and ready for takeoff is a critical task, and refuelers are the unsung heroes of this operation. These specialized trucks or hydrant systems are equipped with pumps, filters, and safety features to ensure the safe and efficient delivery of fuel to the aircraft. They are designed to handle various fuel types and quantities, catering to the specific needs of different aircraft.● De-icing and Anti-icing Equipment: When winter weather strikes, these specialized trucks take center stage. Equipped with powerful spray systems, they apply de-icing and anti-icing fluids to aircraft surfaces, removing ice build-up or preventing its formation. This ensures safe takeoff conditions and mitigates the risks associated with ice accumulation on aircraft wings and control surfaces.● Catering Trucks: Ensuring passenger comfort goes beyond just getting from point A to point B. Catering trucks play a vital role in the passenger experience, delivering food, beverages, and other supplies to the aircraft. These trucks are equipped with specialized compartments to maintain the appropriate temperature for different food and beverage items, ensuring a fresh and enjoyable dining experience at 30,000 feet.● Lavatory Service Carts: Maintaining hygiene and sanitation on board is crucial for passenger health and comfort. Lavatory service carts are specifically designed to service aircraft lavatories, empty waste tanks and replenish water and other essential supplies. These compact yet efficient carts ensure a clean and sanitary environment for passengers throughout the flight.● Maintenance Stands and Platforms: Keeping aircraft in top-notch condition requires regular maintenance and inspections. Maintenance stands and platforms provide technicians with safe and convenient access to various parts of the aircraft, from engines and landing gear to fuselage panels and avionics systems. These stands come in various sizes and configurations to accommodate different aircraft types and maintenance tasks.The Impact Of GSE on Aviation Safety And EfficiencyGSE plays a pivotal role in ensuring both the safety and efficiency of aircraft operations on the ground. Let's break down how:● Safety First: GSE is designed with safety as a top priority. Think about it: aircraft are incredibly complex machines, and any misstep during ground operations can have serious consequences. GSE helps mitigate risks by providing:○ Secure aircraft movement: Tractors and pushback tugs ensure precise maneuvering, preventing collisions and damage.○ Stable ground power: GPUs provide reliable power to critical aircraft systems, reducing the risk of electrical failures.○ Safe boarding and disembarking: Passenger boarding bridges eliminate the hazards of stairs and ground-level boarding.○ Efficient de-icing: Specialized de-icing equipment minimizes the risk of ice-related incidents during takeoff.● Efficiency is Key: In the fast-paced world of aviation, time is money.
