Q

EFIS ADC SOURCE reversion selector

A

provides the crew with the ability to control the Air Data Computer source

17
Q

ALL pushbutton

A

with the MFD 1 or 2 selector set to SYS, ALL pushbutton cycles through all available systems, will continue to remain operative after an Engine and System Integrated Display control panel power loss

18
Q

EFIS ATT/HDG SOURCE reversion selector

A

provides the crew with the ability to control the AHRS source on the EFIS

19
Q

IAS MISMATCH message

A

ADC 1 and ADC 2 are providing different IAS values

20
Q

PITCH MISMATCH or ROLL MISMATCH message

A

inertial sources are providing different pitch and/or roll values

21
Q

ALT MISMATCH message

A

ADC 1 and ADC 2 are providing different barometric altitudes

22
Q

Altitude mismatch threshold

A

ground - 60 ft

increases to 180 ft at FL 270

23
Q

Automatic screen reversion

A

ED fails and is automatically transferred to MFD 1

24
Q

The Attitude and Heading Reference System (AHRS) consists of:

A

two AHRS control panels
two Attitude/Heading Reference Units
two remote flux valves
two remote Memory Modules

25
Q

The Attitude and Heading Reference Units (AHRU 1/AHRU 2) supply specific altitude and heading parameters directly to the following systems:

A

Electronic Instrumentation System (EIS)
Auto Flight Control System (AFCS)
Stall Protection System (SPS)

26
Q

The Electronic Instrumentation System (EIS) shows the Attitude and Heading Reference Units (AHRU 1/AHRU 2) parameters that follow:

A

Electronic Attitude Direction Indicator
Electronic Horizontal Situation Indicator
Altitude
Intertial Vertical Speed Indicators

27
Q

The AHRUs also supply specific altitude and heading data to the systems that follow through the two Integrated Flight Cabinets (IFC 1, IFC 2):

A 
Flight Data Recorder
Flight Data Processing System
Weather Radar
Ground Proximity Warning System
Traffic Collision Avoidance System
Central Diagnostic System
28
Q

The AHRS operating modes are:

A

Alignment
NORMAL or BASIC mode for attitude
SLAVED or DG mode for heading

29
Q

When does AHRS alignment mode start and how long does it take?

A

automatically starts at the end of a 5 second power on self test, parameters are available approximately 20 seconds after alignment mode is started; manual realignment mode takes approximately 60 seconds on the ground and 90 seconds in flight

30
Q

How do the AHRUs work?

A

Uses vertical and direction gyros and accelerometers to sense rate of airplane movement which provide pitch, roll, and heading information. AHRS delivers a baro-inertial vertical speed and a baro-inertial altitude to each PFD. AHRS selects ADC input according to the ADC source reversion controlled by Crew.

31
Q

Describe AHRS NORMAL mode.

A

AHRUs use their associated ADUs parameters for attitude and automatically calculates and corrects for errors

32
Q

Describe AHRS SLAVE mode.

A

AHRU slaves its internal heading with analog magnetic heading information as calculated from analog signals from the flux valve and automatically compensates for heading errors

33
Q

Describe AHRS BASIC mode.

A

automatically activated when the TAS parameter becomes unavailable, causes decreases attitude accuracy, EADI will behave like a conventional mechanical gimbaled gyro

34
Q

Describe AHRS BASIC mode.

A

automatically activated when the TAS parameter becomes unavailable, causes decreased attitude accuracy, EADI will behave like a conventional mechanical gimbaled gyro

35
Q

Two primary channel Air Data Units (ADU 1, ADU 2) function independently and receive inputs from:

A 
two pitot static probes
air temperature probe
Index Control Panels (ICP 1, ICP 2)
Proximity Switch Electronic Unit (PSEU)
ADC test switch
36
Q

The Air Data System (ADS) senses static pressure, pitot pressure, and static air temperature and converts it into electronic data which is used by the following systems:

A 
cabin pressure control
flight guidance 
flight controls
indication
Vmo / Mmo warning
navigation 
powerplant operation
37
Q

The Electronic Instrument System (EIS) displays the following ADU parameters:

A

Indicated Air Speed on the PFDs
True Airspeed displayed on the MFDs
Static Air Temperature displayed on the ED

38
Q

What happens to altitude and IVSI when the AHRS is not valid?

A

When the AHRS altitude is not valid, the PFD displays uncorrected ADC altitude only. Therefore, altitude is only failed when selected ADC is failed, independently of AHRS altitude validity. Loss of AHRS or ADC will cause IVSI FAIL, until a manual reversion is performed.

39
Q

What does the PACIS provide?

A

Private voice communication between Flight Deck and Cabin Crewmember (CALL or EMER), visual and aural notification of interphone calls
