Dynamic Pressure (q) ram pressure can be calculated by measuring
differential pressure:
q = Ptot − Ps
Where can you find baro correction for the air data system? The assigned
instruments for Flight Monitoring
EFIS
A voice recorder is used to record the communication of the pilots and the
sounds in the cockpit. It is used for accident investigation after a crash
Cockpit Voice Recorder
The transmission starts automatically when the battery of the beacon comes
in contact with water and continues for a minimum of 90 days approx. 3000
meters
ULB-Underwater Locator Beacon
True heading is in reference to the geographic North Pole.
Also called true north, or TN in short

other and when a certain difference is exceeded, both AP disengage
completely?

Track
GPS can calculate the aircraft latitude, longitude, and altitude when the
distance is at least how many satellites?
