AUTOFLIGHT Flashcards
What is meant by DUAL INDEPENDENT and SINGLE FMGS modes?
- 2 FMGS’s working
- 2 FMGS’s working but different info (no cross fill)
- 1 FMGS unserviceable
What information is displayed on the metric altimeter indication?
The FCU selected altitude converted to meters
What happens if you push the V/S selector knob?
Level Off (V/S 0 ft/min)
What information does the yaw bar give?
When is it displayed?
- Deviation from runway center line
- On the ground when a LOC signal is available
When is the autopilot available for use?
> 100 ft AGL or 5 sec after take off
When can you use both autopilots?
If approach button is pressed and a coupled approach is executed
Why should the Auto Pilot not be switched OFF via the AP FCU buttons?
Generates a LVL 3 warning with a Continuous Cavalry Charge
What happens to the IAS bug if FD’s and AP’s are switched off?
Turns BLUE
To what speed does the Descent Profile lead and at which altitude will that speed be reached?
- Vapp
- At 1000 ft above runway elevation
A managed descent in a holding pattern gives which rate of descent?
1000 ft/min
What happens to constraints if OPEN DES/CLB is initiated?
They are no longer adhered to
What does SRS stand for?
Speed Reference System
What is GA/TRK exactly?
It is the aircrafts current track on selecting TO/GA
With the A/THR active, actual thrust will be limited to what?
CLB thrust
In the armed mode, actual thrust is equal to what?
The position of the thrust lever
What happens to A/THR if the Thrust Levers are moved to IDLE?
- A/THR disconnects
- A/THR Blue
What happens if the A/THR disconnect buttons are pressed for more than 15 sec?
A/THR disconnects for the remainder of the flight
All A/THR functions including alpha-floor are lost
What happens to the thrust setting if you disconnect the A/THR with the disconnect buttons?
It will go to the thrust corresponding to the thrust lever setting
If the levers are set to CLB and A/THR is active, what happens if you move the levers forward of the CLB detent?
active -> armed
A/THR blue on FMA
Thrust levers control thrust directly
“MAN THRUST” in white
At what RA does one hear “RETARD”:
On an autoland?
On a manual landing?
10 ft RA
20 ft RA
What is the minimum speed possible with A/THR ON?
VLS (Lowest Selectable)
What is Ground Speed MINI?
Vapp - Twr HeadWind. It keeps the aircrafts energy constant until Touch Down
What does a temporary white box around a mode indication mean on the FMA?
This new mode will be active in 10 sec
When does LAND appear on the FMA?
On an ILS approach (GS and LOC) 400’ RA
What is the only way to get out of LAND mode?
- TOGA
When do you get the message DECELERATE?
When you overshoot the TOD (calculated by FMGC)
Why do you get the message MORE DRAG?
The aircraft is above the vertical profile and predicts that with an IDLE descent, the profile will be intercepted
When can “SPEED, SPEED, SPEED” be heard?
- 2000’ RA and 100’ RA
- The system predicts a loss of energy and that thrust has to be increased to maintain your flight path and pitch attitude
What triggers alpha-floor?
Does A/THR need to be active?
- High AoA
- NO
When is Wind shear protection available?
When is it triggered?
What do you see and hear?
- TO: 3 sec after lift off until 1300’ RA with at least config 1
LND: 1300’ RA until 50’ RA with at least config 1 - When the FAC’s calculate that the energy level will fall below a certain threshold
- Red “WINDSHEAR” message on both PFD’s for a minimum of 15 sec and an aural voice announcing “WINDSHEAR” three times
When is ALPHA-FLOOR available?
from lift-off on TO until 100’ RA before landing
What causes the memo “SPEED BRK” flashing amber to appear?
At level OFF with speed brakes extended, N1 >50% N1 (speed brakes should be retracted)
What happens on the PFD altitude tape when the aircraft descends below the MDA?
AMBER RA
What is displayed in the top centre of the ND?
Runway name and type of approach selected when within 250 Nm of the destination
What does a triangle mean after a waypoint?
Mandatory overfly point
What happens if you overfly a MAGENTA D in managed navigation?
Aircraft will start to decelerate towards Vapp
What is the effect of activating the approach phase?
In managed speed it will decelerate to green dot speed
After a Go Around, what will be strung in the F-PLAN page?
Another approach (the same as before)
What happens to the RA indication during a CAT III A approach with decision height 50’ RA?
