Flight Instruments Flashcards
What are the units on the DAD stack?
Display control panel
Air data reference panel
Display reversionary panel
What is the FCP?
Flight control panel; controls the autopilot and displays on FMA (Flight mode annunciator)
What is the IRS
Inertial reference system; measure inertial motion with lasers and computes attitude and heading data.
What is lost following an ADC failure?
Airspeed, altitude, vertical speed, SAT/TAT
What reversion is possible following ADC failure?
Use source select to choose cross side ADC as a source.
What is lost following an IRS/AHRS failure?
Attitude, heading, angular rates, linear acceleration
*IRS may lose present position
What reversion is possible following IRS/AHRS failure?
Source select panel and select Attitude/heading.
What does an EFIS COMP MON CAS message represent?
Data on PFDs does not match usually indicating a computer failure.
*Could also rarely be a magnetic anomaly area.
At what altitude will the RA no longer be displayed?
2500’ AGL or 1225 analog
Name some systems that use the Pitot static system for inputs:
ADCs, EFIS, ISIS, Transponder, Stall protection, FADEC, FMS
What happens following a PFD Failure?
Use display reversionary panel to move it to the PFD. Will not automatically move.
How long will you be able to continue to use your standby instrument following complete loss of AC and DC power?
As long as you have battery power (30 minutes typically)
Which approaches can be flown using the ISIS?
ILS/LOC
What color needles would show for the following approaches: Cross side, ILS, VOR, GPS
Cross side: Ambre
ILS/VOR: Green
GPS: White
Components of AHRS System are:
2 AHRS Computers
2 Flux detectors
2 Remote compensator units
