10 to 11 minutes
From which source do the captain’s flight instruments receive AHRS information?
AHRS 1 or IRS 1
From which source do the first officer’s flight instruments receive AHRS information?
AHRS 2 or IRS 2
From which source do the captain’s flight instruments receive pitot/static information?
System #1 pitot/static tube on left side of nose
From which source do the FO’s flight instruments receive pitot/static information?
System #2 pitot/static tube on right side of nose
From which source does the integrated standby instrument receive pitot/static information?
System #3 standby pitot under captain’s side window and two alternate static ports, one on left and one on the right side
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
When and where will the radio altitude information appear?
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 indicate?
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
How many flight directors are installed?
two
How many autopilots are installed?
one
What does the autopilot follow when engaged?
The selected side flight director which defaults to the captain’s FD.
The XFER button must be selected on the flight control panel to transfer to the FO’s FD
What happens when TOGA is pushed on the ground?
Autopilot disengages
TO lateral and vertical mode
FMS aligns the aircraft at the end of the runway indicated on legs page
What does the TO lateral mode do?
On the ground, it generates a wings level command.
In the air it generates a heading hold command with a 5° bank limit using the heading existing at takeoff
What does TO vertical mode do?
Generates an optimized pitch up attitude for takeoff
What happens when TOGA is pushed in flight?
Autopilot disengages
GA lateral and vertical mode
Missed approach procedure depiction appears on the MFD if instrument approach procedure selected in FMS
What does GA lateral mode do?
Same as TO lateral mode and follows heading flown when TOGA was pushed
What does GA vertical mode do?
Generates a 10° pitch up attitude
After takeoff or go-around, the autopilot must not be engaged below what altitude?
600 ft AGL
During visual and non-precision approaches, the autopilot must be disengaged by?
400 ft AGL
During precision approaches, the autopilot must be disengaged by?
80 ft AGL
During single-engine precision approaches, the Autopilot must be disengaged by?
80 ft AGL (700), 110 ft AGL (900)
When will autopilot automatically disconnect?
- AP/SP DISC button pushed,
- AP ENG button on FCP pushed,
- AP DISC switch bar pushed down,
- stick shaker activated,
- TOGA buttons pressed,
- STAB TRIM manually operated,
- windshear warning (after 2 seconds),
- excessive attitude,
- one or both FCCs fail, both yaw dampers disc or fail.
