16
Q

Are directional gyro north seeking?

A

No, must be manually set by referring to magnetic compass, cage first (pull)

17
Q

What must you do to a directional gyro prior to using?

A

Initial alignment

18
Q

How often do Heading indicators need to be realigned?

A

every 15min

19
Q

What system provides automatic presentation of accurate magnetic headings and eliminates the need to manually transfer heading info?

A

Slaved compass system

20
Q

Where are flux valves and magnetometers located?

A

Wing or tail (far away from engine)

21
Q

What are the two magnetic sensing devices?

A

Flux valve and Magnetometer

22
Q

What is the advantage of a magnetometer compared to a flux valve?

A

Can sense horizontal and vertical components of the Earths magnetic field

23
Q

What does the ADI measure?

A

Pitch and roll

24
Q

The ADI gives an _________ indication of even the smallest changes in altitude

A

Instant

25
Q

How do you level the ADI?

A

Cage it first and torqueing motors

26
Q

How must you handle the gyro?

A

Handle like eggs and wait 20min after powering down

27
Q

What are some advantages of EFIS?

A

Less maintenance = no moving parts Less weight = data bus system Less expensive = same video displays Reduce pilot workload = show relevant info

28
Q

What are the 2 functions of EIS

A

EFIS and EICAS

29
Q

This display format includes: nav maps, weather radar, TCAS traffic and aircraft maintenance data

A

MFD

30
Q

This display format includes: critical engine and system status data recording and display as needed

A

EICAS

31
Q

What are the colours on EICAS and what do they mean?

A

red = warning yellow/amber= caution blue/white= advisories

32
Q

What are synoptic pages?

A

Graphical depictions of aircraft systems

33
Q

What will an integrated standby instrument display?

A

ADI and HSI in case of full EFIS failure

34
