A small plastic or metal reinforcing ring attached to the fabric covering at low points in the structure and at the trailing edges of the wing and tail surfaces. Grommets are used to reinforce the drain or vent holes cut in the fabric at these locations. A marine grommet, also called a seaplane grommet, differs from ordinary grommets because of a shield placed over the hole. This shield keeps the spray during takeoff and landing from getting into the structure.
Industry:Aviation
A small plate attached to two or more members of a truss structure to strengthen the truss.
Industry:Aviation
A small postcard-like form used by repair stations, maintenance shops, and technicians to report to the FAA a defect or unacceptable condition discovered in an FAA-certificated component. Information gathered on M & D reports allows the FAA to identify and track weaknesses in certificated products that could create a safety problem. M & D reports provide the basis for the General Airworthiness Alerts and subsequent Airworthiness Directives.
Industry:Aviation
A small pump in a carburetor used to produce a momentarily rich fuel-air mixture to the engine when the throttle is suddenly opened.
The fuel supplied by the accelerating pump prevents the hesitation that would otherwise occur between the time the engine stops operating on the idle metering system and the time there is enough air flowing through the carburetor for it to supply fuel through the main metering system.
Industry:Aviation
A small receiver, or earphone, mounted on a band worn over the head. Most headphones have two receivers mounted in soft cups so one can be comfortably worn over each ear.
Industry:Aviation
A small rocket engine whose thrust is used to change the attitude of a space vehicle.
Industry:Aviation
A small rotor on the tail of a single-main-rotor helicopter which produces a force to counteract the torque of the main rotor.
The pitch of the blades of an auxiliary rotor may be controlled by the pilot to rotate the helicopter about its vertical axis.
Industry:Aviation
A small self-contained radio transmitter carried in an aircraft. If the aircraft crashes, the force of the impact automatically sets the transmitter into operation, transmitting a series of down-sweeping tones on the two emergency frequencies of 121.5 and 243.0 megahertz. Searchers who receive the signal from the ELT are able to locate the wreckage by using radio direction finding equipment.
Industry:Aviation
A small self-contained turbine- or reciprocating-engine-powered generator, hydraulic pump, and air pump.
APUs are installed in an aircraft and are used to supply electrical power, air, and hydraulic pressure for ground operation and for starting the main engines.
Industry:Aviation
A small skid mounted on the bottom of the aft end of the fuselage of an airplane equipped with a tricycle landing gear. The tail skid absorbs the shock and prevents damage to the structure if the airplane should be rotated too abruptly on takeoff.
In the early days of aviation when airplanes had no brakes and operated from grass fields, tail skids were used rather than tail wheels to support the tail of the airplane when it was on the ground.
