ATO Test 5 Exam Questions with
Detailed Solutions
Attitude Heading reference system - -Conventional system which serves as a
backup for aircraft equipped with an INS.
- Displacement gyroscope - -A hermetically sealed, two-gyroscope platform
providing pitch, roll, and azimuth signals to the system indicating instruments
- Compass Transmitter (Flux Valve) - -Senses the direction of the earth's magnetic
field and develops a proportional signals
