Avionics/ Electrical Flashcards
Barometric Altimeter
Indicates altitude above sea level
RADAR Altimeter
Determine alt above ground lvl
Azimuth
Angular position or bearing in horizontal plane
Bearing
Angular position of object with respect to reference point
Range
Distance of object from observer
Heading
Orientation of aircraft longitudinal axis
True heading
Direction measured by true north
Magnetic heading
Direction of earth’s magnetic field at that location as reference
Relative heading
Current direction that an object if facing as the 0/360 azimuth alignment
Fiber Optic Cables
Improved system performance, reduced size and weight, system economy
VHF/UHF
Communicate with other aircraft, ground stations
IAS (intercommunication Audio System)
Communication between cockpit and ground crew and rear cockpit
TACAN
Aircraft position and determine bearing and slant range
INS (Inertial navigation system)
Dead reckoning navigation system (detects motion, acceleration, velocity position, pitch roll
GPS
Navigation system received from satellite
ARI (Attitude Reference Indicator)
Self-contained pitch and roll
Instrument Landing System
All weather approach guidance system
