Inaccurate visual information for aligning the aircraft, caused by various natural and geometric formations that disorient the pilot from the actual horizon.
Industry:Aviation
An electronic altimeter that determines the height of an aircraft above the terrain by measuring the time needed for a pulse of radio-frequency energy to travel from the aircraft to the ground and return.
Industry:Aviation
A small circle graduated in 360° increments, to show direction expressed in degrees.
Industry:Aviation
The lowest altitude at which an airway intersection can be determined.
Industry:Aviation
A problem that mostly affects gasoline-fuelled internal combustion engines. It occurs when the liquid fuel changes state from liquid to gas while still in the fuel delivery system. This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling. Restarting the engine from this state may be difficult. The fuel can vaporise due to being heated by the engine, by the local climate or due to a lower boiling point at high altitude.
Industry:Aviation
Class E airspace areas that extend upward from 1,200 feet to, but not including, 18,000 feet MSL, unless otherwise specified.
Industry:Aviation
An electromagnetic (EM ) wave with frequency characteristics useful for radio transmission.
Industry:Aviation
An aircraft with retractable landing gear, flaps, and a controllable pitch propeller.
Industry:Aviation
The minimum altitude depicted on approach charts which provides at least 1,000 feet of obstacle clearance for emergency use within a specified distance from the listed navigation facility.
Industry:Aviation
Compass error caused by the difference in the physical locations of the magnetic north pole and the geographic north pole.
