or unblock the system using high psi air - ✔✔False
It is safe to connect or disconnect psi lines when using high psi air supplied by the
Air Data Test Set - ✔✔False
What type of fault would show erratic or sluggish indicator observed on one or
more affected indicators? - ✔✔excessive moisture
Which Angle of Attack component measures the true angle of attack by
determining the angular difference between local airflow and fuselage reference
plane? - ✔✔Airstream Direction Detection (ADD) Transmitter
Where is the output of the Airstream Direction Detector (ADD) Transmitter sent? -
✔✔to the amplifier of AOA indicator

____________ and the approach lights relay is ___________ - ✔✔energized
de-energized
What is the purpose of the AOA lights transformer? - ✔✔provides 6.2 VAC to the
