To safeguard the airport from any kind of intrusion from areas outside its boundary competent authorities have defined the specifications of airport boundary wall that are to be maintained at every aerodrome.
The height of the wall should be not less than 8 feet with barbed wire fencing of not less than 1.5 feet, and it should run along the airport boundary as far as possible.
An approach lighting system or ALS, is a lighting system installed on the approach end of an airport runway and consisting of a series of lightbars, strobe lights, or a combination of the two that extends outward from the runway end. ALS usually serves a runway that has an instrument approach procedure (IAP) associated with it and allows the pilot to visually identify the runway environment and align the aircraft with the runway upon arriving at a prescribed point on an approach.
An auxiliary power unit (APU) is a small jet engine on the aircraft that provides energy for functions like providing electrical power to aircraft systems as well as bleed air for air conditioning and for engine start. Aircraft APUs generally produce 115 V AC voltage at 400 Hz (rather than 50/60 Hz in mains supply), to run the electrical systems of the aircraft; others can produce 28 V DC voltage. This is also used to start one engine of the aircraft.
Anti-collision lights, also known as Beacon lights or Strobe lights are a set of lights required on every aircraft to improve visibility to others. Beacon lights are flashing red lights fitted on the top and bottom fuselage of an aircraft usually on larger passenger aircraft. Their purpose is to alert ground crew and other aircraft that an engine is starting up, running or shutting down, or that the aircraft is about to start moving.
Ambulift ALS-U is designed to transport passengers with disabilities and their attendants to and from aircrafts, as well as to assist them with boarding and disembarking.
The passenger cabin is fitted with lights and a ventilation system. There is also an intercom available inside the cabin to ensure communication between passengers and an ambulift operator. Additionally, the cabin is equipped with restraining systems for stretchers and wheelchairs, a cabinet and seating places for attendants. Non-slip grip handrails are installed on both sides inside of the cabin. A rear platform allows for the installation of a special device to transfer stretchers from the platform into the cabin. Foldable rail guards are installed all around the platform.
Ambulifts can be equipped with climate-control systems, as well as special needs wheelchairs.
Air Traffic Controller (ATC)
Air traffic control is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through controlled airspace, and can provide advisory services to aircraft in non-controlled airspace.
A designated area at an aerodrome suitable for the loading and off loading goods, embarking and diembarking passengers, refuelling, reecatering, and other small checks of an aircraft.
An airport crash tender is a specialized fire engine designed for use in aircraft rescue and firefighting at aerodromes, airports and military air bases. These are the first vehicle to respond at an emergency site in the airside. These vehicle contains water and foam and a expelling agent(Nitrogen). It also contains some equipments such as cutter, Jockey Pump, high visibility jacket, helmet, etc which can be used during fire fighting.
It is a construction made at remote ends of an airport where any suspected baggage with threat of explosive is taken to and kept in isolation. If such bags explode inside a cooling pit the effect of such explosion on nearby infrastructure is minimal.
Aircraft have emergency exit doors to be used in case to evacuate the aircraft in case of emergencies. generally,
only passengers who meet certain requirements(young and fit) can sit in the seats next to these doors. Procedures to operate these doors are explained before the flights departs to the person sitting close to it. There are markings on the aircraft floor to guide passengers to these doors during emergencies.
