Avionics, Flight Instruments Flashcards
How should we contact the flight attendant in an emergency
PA, push the EMER call switch light to generate three high/low chimes and a flashing red light on the FA’s overhead panel

We hear one high/low chime and the EMER call switch light will be flashing
How do we know if the company is trying to contact us
An ACARS message of SELCAL voice aural and a SELCAL advisory EICAS message

30-70 seconds
In DC mode, how long does it take AHRS system to initialize
10-11 minutes
From which source do the captains flight instruments receive AHRS information
AHRS 1 or IRS 1
From which source do the first officers instruments receive AHRS information
AHRS 2 or IRS 2
From which source do the captains flight instruments receive pitot/static information
F/O’s information
System #1 pitot/static tube on right side of the nose
System #2 pitot/static tube on the left side of the nose
From which source does the integrated standby instrument receive pitot/static information
System #3 standby pitot under captains side window and two alternate static ports, one on left and one on the right side
Will the flight deck PA override the flight attendant PA?
Yes
Where is the TAT probe located?
Under FO’s side window
What is the definition of Total air temperature
The temperature of the air corrected for compressibility and friction caused by high speed
On the ground with the probe heat ON, which probes are heated?
All pitot probes are heated half way, all others are fully heated except the TAT probe which is not heated on the ground
In flight, which probes are heated
All are fully heated regardless of probe heat switch position
Is there a LOC and GS indication on the standby attitude indicator
Yes, referencing NAV 1

0 to 2500 AGL indicated in green below the altitude tape
What does the speed trend vector indicate
Predicted airspeed in 10 seconds if no changes are made
When and where will the MACH readout appear
Appears when accelerating through 0.45 Mach. Disappears when decelerating through 0.4 mach. Appears just above the airspeed tape in white.
What does the green line on the airspeed tape indicated
1.27 Vs based on current configuration. Not accurate at high altitudes
Where is the slip and skid indicator located
A rectangle located just under the sky pointer
