20
Q

In heading mode, are turns commanded in the same direction as selected heading bug movement, even if the bug is turned more than 180 deg from the present heading?

A

Yes

21
Q

What criteria must be met for Emergency Descent Mode (EDM) to be armed?

A

-Airplane Pressure Altitude >25,000’
-Autopilot Engaged

22
Q

What criteria must be met for Emergency Descent Mode (EDM) to activate?

A

CAB ALTITUDE HI (CAS) is displayed

23
Q

What actions are automatically accomplished by Emergency Descent Mode (EDM)?

A

-EDM annunciation
-Selected Altitude set to 15,000’
-Heading Bug set to 90 deg left of current heading
-Transponder code set to 7700
-Airspeed Reference set to 250 KIAS/Mmo

A

Yes

25
Q

How may Emergency Descent Mode (EDM) be deactivated?

A

Quick Disconnect Button only

26
Q

Where are the ADC processors located within each air data system?

A

Within the respective IASP probe units for ADS 1 & 2, and within the EISI unit for the standby system.

27
Q

What is the data source for the following?
-Air Data System (ADS) 1:
-Air Data System (ADS) 2:
Air Data System Standby:

A

-IASP 1 probe unit
-IASP 2 probe unit
-Pito-Static (standby) probe and integrated Electronic Standby Instrument (IESI

28
Q

What is the normal air data source for the following display units?
-PFD 1/ MFD:
-PFD2:

A

-ADS 1
-ADS 2

29
Q

What automatic air data source reversions occur for the following display units?
-PFD 1/ MFD:
-PFD 2:

A

-ADS 2 (ADS Standby if both ADS 1 and ADS 2 fail)
-ADS 1 (ADS Standby if both ADS 1 and ADS 2 fail)

30
Q

What sensors are used by the AHRS units to compute attitude and heading information?

A

-Onside ADS (Air Data System)
-Onside Magnetometer Unit
-Both GPS sensors

31
Q

What is the normal attitude/ heading reference for the following display units?
-PFD 1/ MFD:
-PFD 2:

A

-AHRS 1
-AHRS 2

32
Q

What automatic attitude/ heading reference reversions occur for the following display units?
-PFD 1/ MFD:
-PFD 2:

A

-AHRS 2 (IESI attitude reference if both AHRS 1 and AHRS 2 fail

-AHRS 1 (IESI attitude reference if both AHRS1 and AHRS 2 fail)

33
Q

Give the following data source information for the Integrated Electronic Standby Instrument (IESI)

A

-Power: Emergency Bus (Primary), DC BUS 1 (Secondary)

-Attitude: Internal Gyro System (no heading)
-Heading: AHRS 1
-Air Data: Pitot Static (Standby) probe and ADC processor internal to IESI unit

-Navigation: ILS1/ILS2

34
Q

Are ADC, Heading, or Altitude reversions available for the Integrated Electronic Standby Instrument (IESI)?

A

No

35
Q

Does the Integrated Electronic Standby Instrument (IESI) contain or source a dedicated AHRS unit?

A

No, the IESI attitude reference contains its own internal gyro system but does not contain heading data.

36
Q

How may heading data be referenced for navigation in the event of a dual AHRS failure?

A

-The GPS page contains track info and while track differs from heading depending on winds, is the most reliable reference.
-Standby Compass
