Automated cockpit Flashcards
What happens alerts will happen if one FMC should fail?
FMC fail on the CDU
FMC FAIL on upper EICAS
That EHSI will display MAP flag
How many FMC’s are there and which is the master and which is the slave?
2
Captains is master, first officer is the slave (unless captains fails, then vice versa)
What would the first officer do if his FMC failed?
Select ALTERNATE FMC
What instruments would be supplied by captains FMC in event of FO’s FMC failing?
EHSI and EADI screens to be supplied info from captains FMC
What is recommended when entering data into CDU?
One used at a time, ie one to enter data the other to check it
What can autothrottle be manually overriden by?
Thrust mode select pannel (TMSP)
Moving autothrottle from ARM to OFF
What does autothrottle do when selected in N1 mode?
Controlling to the selected N1 thrust selection
What does autothrottle do when selected in the SPD mode?
Maintains speed selected in the speed window
OR if in VNAV mode, the speed programmed in the FMC
What does autothrottle do when selected in the FLCH mode?
A/T controlling to climb thrust during climb and to minimum N1 during descent
What does autothrottle do when selected in GA mode?
A/T controlling to max of go around reference thrust.
Maintain climb rate of at least 2000fpm with GA displayed as pitch mode
What does autothrottle do when selected in IDLE mode?
A/T reducing thrust to flight idle.
May engage in VNAV descent
Will engage when FLARE is engaged prior to touchdown
What does autothrottle do when selected in THRUST HOLD mode?
Thrust levers remain in existing position or where manually placed by pilot
What switch must be on for the various autopilot functions to be operational?
FD switches
During the initial climb, at what height can pilot select VNAV on the autopilot MCP?
400 feet radio altitude (AGL)
During the initial climb, what happens with regards to the autopilot at 400 feet radio altitude?
Pilot selects VNAV on autopilot MCP
EADI pitch mode changes from ‘TO’ to ‘VNAV SPD’
When autopilot is engaged and VNAV is displayed on EADI, what is the FMC controlling?
Aircrafts vertical path through the autopilot and autothrottle
When the autopilot is engaged and the LNAV is displayed on the EADI, what is the FMC controlling?
Lateral profile through the autopilot
What is the ‘FAIL PASSIVE’ mean with autopilot approaches?
Should one of the two autopilots be disconnected, the aircraft will be left in a passive trim condition
What is FAIL OPERATIONAL mean with autopilot approaches?
Use of three autopilots, if two autopilots agree, then it will remain operational and continue to fly the aircraft for CAT 3 autoland approaches
When using the vertical path to glideslope capture, what appears on EADI and what colour?
VNAV PATH above armed mode of G/S in white
What happens after glideslope capture?
VNAV PATH will be replaced by G/S in green
What happens during glide slope capture at 1500 feet?
EADI shows FLARE in white below active pitch mode of G/S
When is FLARE mode active?
45 feet radio altitude
What happens after FLARE mode?
ROLLOUT mode appears in white below active roll mode of LOC
