Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air, or, in general, the atmosphere of a planet. An aircraft counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines.Although...

 and the time it departs on its next flight. Speed, efficiency, and accuracy are important in ground handling services in order to minimize the turnaround time (the time during which the aircraft remains parked at the gate).

Small airlines sometimes subcontract maintenance to a much larger and reputable carrier, as it is a short-term cheaper alternative to setting up an independent maintenance base. Some airlines may enter into a Maintenance and Ground Support Agreement (MAGSA) with each other, which is used by airlines to assess costs for maintenance and support to aircraft.

Most ground services are not directly related to the actual flying of the aircraft, and instead involve other service tasks. Cabin services ensure passenger comfort and safety. They include such tasks as cleaning the passenger cabin and replenishment of on-board consumables or washable items such as soap, pillows, tissues, blankets, and magazines. Security checks are also made to make sure no threats have been left on the aircraft.
Airport ground support equipment (GSE) comprise a diverse range of vehicles
and equipment necessary to service aircraft during passenger and cargo loading and unloading,
maintenance, and other ground-based operations. The wide range of activities associated with
aircraft ground operations lead to an equally wide ranging fleet of GSE. For example, activities
undertaken during a typical aircraft gate period include: cargo loading and unloading, passenger
loading and unloading, potable water storage, lavatory waste tank drainage, aircraft refueling,
engine and fuselage examination and maintenance, and food and beverage catering. Airlines
employ specially designed GSE to support all these operations. Moreover, electrical power and
conditioned air are generally required throughout gate operational periods for both passenger and
crew comfort and safety, and many times these services are also provided by GSE.

 system which blocks the wheels from moving when the connecting rod is not attached to a tug. Most carts are completely enclosed except for the sides which use plastic curtains to protect items from weather.

Trollies for containers and pallets



The trolley or dollie are for containers and palettes are used for the transport of loads placed in containers and on pallets. Both kinds of trolley have inbuilt rollers or balls in the space for the acceptance of containers or pallets for their easier moving. The containers or pallets on trolleys must obligatory be secured with built-in Stops. The mechanical brake, depending on construction blocks the wheels when the towbar of the trolley is raised to 90°. The trolleys for containers have revolving deck to make containers turn to the direction of loading on aircraft. On all trolleys the parts as brake for wheels blocking, the wheels, the towbar, the hook for connecting, stops on the revolving platform, and stops for locking the containers or pallets must be in order or with them is prohibited any transport.

Refuelers

Aircraft refuelers can be either a self contained fuel truck, or a hydrant truck or cart. Fuel trucks are self contained, typically containing up to 10,000 US gallons of fuel and have their own pumps, filters, hoses, and other equipment. A hydrant cart or truck hooks into a central pipeline network and provides fuel to the aircraft. There is a significant advantage with hydrant systems when compared to fuel trucks, as fuel trucks must be periodically replenished.

Tugs and tractors

The tugs tractors at an airport have several purposes and represent the essential part of ground support services. They are used to move any equipment that can not move itself. This includes bag carts, mobile air conditioning units, air starters, lavatory carts, and other equipment.

Container loader

The loader for widebodied aircraft (cargo platform) is used for loading and unloading of cargo placed in containers or on pallet. The loader has two platforms which independently raise or come down. The containers or palettes on the loader are moved with the help of built-in rollers or wheels, and are carried in aircraft across the platforms.
The ground handling is different in the different areas. In Northern and South America the pallet is dominating and in Europe and Asia the container is stronger in use.
So there are different container and pallet loaders.
- 3.5 to
- 7 to, standard version, wide-body, universal (up to main body height)
- 14 to
- 30 to
For military transport planes special container and pallet loaders are in use.
Also for military use airborne (transportable within the transport plane) are in use.
Container and pallet loaders are produced mainly in France, Germany, Estonia, Spain, Canada, in the U.S.A., Brazil, Japan and China.

Transporters

The transporters are cargo platforms constructed so that beside loading and unloading can transport cargo. Depending on the type and load capacity the containers could be transported, and the same is valid for greater transporters and palettes.

 tanks in aircraft. The water is filtered and protected from the elements while being stored on the vehicle. A pump in the vehicle assists in moving the water from the truck to the aircraft.

Lavatory service vehicles

Lavatory service vehicles empty and refill lavatories onboard aircraft. Waste is stored in tanks on the aircraft until these vehicles can empty them and get rid of the waste. After the tank is emptied, it is refilled with a mixture of water and a disinfecting concentrate, commonly called 'blue juice'. Instead of a self-powered vehicle, some airports have lavatory carts, which are smaller and must be pulled by tug.

Catering vehicle

Catering includes the unloading of unused food and drink from the aircraft, and the loading of fresh food and drinks for passengers and crew. The meals are typically delivered in standardized carts. Meals are prepared mostly on the ground in order to minimize the amount of preparation (apart from chilling or reheating) required in the air.

The catering vehicle consists of a rear body, lifting system, platform and an electro-hydraulic control mechanism. The vehicle can be lifted up, down and the platform can be moved to place in front of the aircraft.

In-flight food is prepared in the flight kitchen which is completely HACCP certified facility where food is made in sterile and controlled environments. The packed food is then placed in trollies and wheeled into the Catering truck at the flight kitchen, which can be located within a 5 km radius of the airport.

Thereon the vehicle drives to the airport and is parked in front of the plane. The stabilizers are deployed and the van body is lifted. The platform can be fine controlled to move left-right as well as in-out so that it is aligned with the door correctly.

The body is made of insulated panels and is capable of maintaining temperatures of 0 degrees by means of refrigeration unit.

A special Hi Lift for the A380 plane has been designed and is seen in cities with the A380 traffic.

Some of the manufacturers manufacturing Hi Lifts are Mallaghan Ltd, CTV DOLL, FFG, Byron GSE, Nandan GSE, TLD, Aeromobiles, TIMSAN GSE, etc.

Belt loaders

Belt loaders are vehicles with movable belts for unloading and loading of baggage and cargo of aircraft. A belt loader is positioned to the door sill of an aircraft hold (baggage compartment) for the operation. Belt loaders are used for narrow body aircraft (e.g. 737) and bulk hold of wide body aircraft (e.g. 767 and 747). Baggage stored without containers is known as bulk loading.

Passenger boarding stairs

Passenger boarding stairs, sometimes referred to as 'air-stairs', 'boarding ramps' or 'aircraft steps', provide a mobile means to traverse between aircraft doors and the ground. Because larger aircraft have door sills 5 to 20 feet high, stairs facilitate safe boarding and deboarding. While smaller units are generally moved by being towed or pushed, larger units are self-powered. Most models have adjustable height to accommodate various aircraft. Optional features may include canopy, heat, supplementary lighting and red carpet.

Pushback tugs and tractors

Pushback tugs are mostly used to push an aircraft away from the gate when it is ready to leave. These tugs are very powerful and because of the large engines, are sometimes referred to as an engine with wheels. Pushback tugs can also be used to pull aircraft in various situations, such as to a hangar. Different size tugs are required for different size aircraft. Some tugs use a tow-bar as a connection between the tug and the aircraft, while other tugs lift the nose gear off the ground to make it easier to tow or push.
