Angle Of Attack Sensors Flashcards
1
Q
How do stall warning systems get their data?
A
AOA vane
AOA probe
2
Q
AOA vane (remote)
A
Protrudes from side of aircraft.
Pivoted at front, rotates to align with airflow.
Position gives a direct electronic reading of AOA via transducer.
3
Q
AOA probe (remote)
A
Pressure imbalance infers either a positive or negative AOA.
High pressure in upper section = positve AOA
4
Q
AOA Null seeking rotor - remote
A
concial cylinder, protuding at right angle from aircraft.
Pressure differential created by the pressure entering each slot rotates the probe untill 2 slots are presented equally to the airflow where the pressure differential is 0.
5
Q
Systems requiring AOA input.
A
Stall warning
Flight envelope protection
Air data computer
6
