Q

If the ADS button is pressed twice, what will happen?

A

The ADS 3 reversion will change to the cross-side ADS. If pushed for a third time, the ADS will revert to the original ADS.

25
Where is ADS temperature and wind information provided?
On the top right corner of the MFD in flight only
26
How is the ADS probe heat provided?
A single heating element heats the ADSP and is controlled and monitored by the ADC mounted to the probe.
27
What are the holes on the MFP Multifunction probe (ADS)?
Total Pressure Port (Ram air hole) 2 Alpha pressure ports (on the side just behind the total pressure port) 2 drain holes (towards the middle on the sides)
28
How are pressures measured and computed inside the ADC?
2 Absolute pressure sensors read the pressure from the total pressure port and the Alpha port inside the ADC A differential pressure sensor measures the difference in pressure data between the Apha pressure ports From the 3 measured pressures above, the ADC calculates the local total pressure, local static pressure, and local AOA
29
What powers the IESS?
28VDC power from Essential DC Bus 2
30
What provides air data to the IESS?
ADSP 3 (air data source) and 4 (compensation data source)
31
In the AUTO mode when does the clock elapsed time counter begin?
No WOW and stops when WOW
32
How is the compass light controlled?
STBY/CLK dimmer on the lighting control panel
33
What is the purpose of the static wicks?
To decrease the dangerous effects of lightning discharge to the airframe and to decrease the interference static electricity causes to radio communication.
34
What does ASCB stand for?
Avionics Standard Communication Bus
35
What does pushing out the MIC button on the audio panel do?
Manually activates the mask mic when auto mode (pushed in) fails
36
What connects the VHF antennas to the audio panel?
Antenna signals are sent to the MRC Modular Radio Cabinet, to the Audio Bus, to the respective audio panel
37
What is lost comms indicated by on the MCDU?
Amber dashes in the comm frequencies on the RADIO page
38
What is the HF comm button used for?
Long-range communications Operates in the HF radio band from 2.00-29.99MHz Page 2 of the RADIO page will show the HF radio data for tuning
39
What happens when the CAB button is pressed on the Audio Panel?
The button flashes and the green rainbow light illuminates and a chime sounds. The button flashes faster once the FA has picked up the call. Push once more to establish communication and turn the light steady green.
40
What happens when the EMER button is pressed on the Audio Panel?
A triple hi-lo chime is sounded through the PA system and a steady red rainbow light illuminates. The same triple hi-lo chime will sound if the FA makes an emergency call to the cockpit.
41
There are 3 ramp headphone jack locations. Where are they?
AC GPU panel Mid Avionics Bay DC GPU panel
42
Where is the ramp call horn located?
The horn itself is in the nosewheel gear bay to alert the ground crew. The horn buttons are on the left and right consoles by the oxygen masks.
43
What is the PA priority?
Pilots, FA, Pre-recorded announcements, music system
44
When can the DVDR be erased?
When on the ground with the parking brake set
45
When does the CVR begin and end recording?
As soon as power is supplied and stops when power is removed
46
When does the FDR begin and end recording?
When the engines are turned on or when the aircraft is in the air. It stops when WOW and both engines are turned off.
47
What does the IRS Inertial Reference System compute?
Airplane Position GS Heading Attitude
48
How does the IRS know the starting location of the aircraft?
Via the GPS by loading the GPS position in the MCDU
49
What happens if IRS is pressed in flight?
The IRS source switches and FD modes disengage, AP modes disengage, and can be re-engaged
50
What are the various GPS fault messages that can appear on the MCDU?
GPS RAIM ABOVE LIMITS (Lost Integrity) RAIM WILL EXCEED LIMIT (Integrity exceeds the limit) GPS RAIM UNAVAILABLE (RAIM not available)
51
Where might the ADF feature be installed?
RADIO page 2
52
What type of transponder is installed?
Mode S
53
How many transponders are installed?
2
54
Is it possible to activate VNAV on the ground?
Yes. It will automatically activate at 400’ AGL
55
Can VNAV exceed the set altitude in the altiude selector?
No. The altitude set must be above or below the current altitude for the aircraft to change altitudes in VNAV mode.
56
What is VTA? When is it?
VTA Vertical Track Alert Issued 60sec before the FMS commands a climb, descent, or 1000’ before the level off altitude. There is no VTA if the leveling-off is based on the altitude set in the Altitude Selector.
57
What does the FMS button do?
Makes FMS the primary navigation source and toggles between FMS sources.
58
What is the box on the top left and bottom left of the FMA?
Top Left: Capture Autothrottle Mode | Bottom Left: Armed Autothrottle Mode
