Autoflight and FMC Flashcards
In the FLCH mode what are the autothrottle and pitch mode annunciations in the climb
THR and FLCH SPD
Pushing the LOC/FAC switch arms the AFDS to do what
To capture and track inbound on the front course, or IAN final approach course
When VNAV is active and the FMC is controlling the target speed what does the IAS/MACH window display
It is blank
To which AFDS modes does the bank Limited selector apply
HDG SEL or TRK SEL only
In-flight with the autopilot engaged and both flight director switches OFF, the first flight director switch positioned on activates which roll and pitch modes
Activates the FD in the currently selected autopilot modes
During a Go-around with LNAV path available, at what RA will LNAV automatically arm and activate with the autopilot not engaged?
50’
What do approaches flown with IAN procedures use for vertical path guidance
FMC computed glidepath
How can the LOC/FAC mode be disarmed before capture
Push the LOC/FAC switch a second time
Before takeoff, what is the ACTIVE, FMA roll mode if a HUD take off is selected in the FMC
HUD TOGA (LNAV is not active yet)
How does the aircraft transition from the air “sideslip” mode to the ground “yaw control “mode after landing
On landing, automatic and manual rudder trim inputs are zeroed
What is the minimum autopilot disengage height for an approach to a status B runway
100 foot radio
With LOC and G/S green, can you deselect them
Yes by pressing the APP button, but only above 1500’ RA
What are the available autothrottle modes in manual flight
THR REF, IDLE, HOLD, SPD
What are the heights where you get automatic LNAV activation
50’ manual flight and 200’ autoflight
On takeoff, what happens if you hit TOGA again above 80kts?
You disarm LNAV VNAV, nothing else happens
What happens if you press TOGA straight after takeoff?
You disarm LNAV VNAV and get full power (THR REF)
By what speed do you need to have pressed TOGA by on takeoff?
50kts, else it is too late
What happens to the autothrust mode at 80kts during takeoff
you get HOLD
Does TOGA give you heading or track keeping on takeoff?
Track - select HDG at 400’ if US ATC requires runway heading
What are liftoff speed ranges for all engines and OEI?
V2 +15 to 20 and V2 to V2+15kts
On approach, when is TOGA armed?
Flaps out of up or G/S engagement
What is the target pitch on TOGA during a go-around?
15°
What is the difference when you hit the TOGA switches during a windshear alert
You get the same but with no LNAV engagement
What do you need to remember to do if capturing the MAA and not in VNAV
If you only have ALT, the power rating stays in TOGA, to you need to select CLB using the MCP button
If you capture the target altitude in TOGA, what will the target speed be when the autothrottle changes to SPD?
5 kts under flap limiting speed
On an autoland, with less than 5° drift, when will you get alignment of the a/c
200’
5° to 10° of crab, when do you get alignment
500’ reduces crab to 5° and 200’ further alignment to reduce crab.
If you have more than 10° crab, when do you get alignment
500’ only, you get 5° of sideslip and a/c lands with a minimum crab of 5°
