Autoflight Flashcards
The autoflight systems are
2 FMGEC, 3 MCDU, 1 FCU and 1 flight management source selection#
The FMGES is basically
The 2 FMGEC
How many channel the FCU has
2
The nav database is stored in
The FMGEC
What are the 2 types of guidance
Managed and Selected
The selected guidance has
Priority over the managed guidance
Pushing activate the
Managed mode
Pulling activate the
Selected mode
The FMGES tunes the NAVAID to
Determine the A/C present position
Each FMGEC has
Nav database, AMI, perf database and magnetic variation database
The navigation database are updated every
28 days
There is enough space to create and store
5 routes, 20 wpts, 10 runways and 20 navaids
The input from the FCU is sent
FMGEC at all times
Both FMGEC are synchronized but
1 can fail and normal ops are maintained
MCDU 3 is normally
A backup unit
In normal situation, AP 1 uses
FMGEC 1 and vice-versa
When both AP are used (DUAL mode), which FMGEC is used
1 is always the master
When no AP and FD engaged, autothrust is controlled by
FMGEC 1
If there is a major mismatch of datanase or operation program, the FMGEC will
Auto switch to independant mode, each FMGEC receives from it’s onside MCDU and controls onside EFIS and RMP
The thrust levers are
The main interface between the FMGEC and FADEC
The thrust levers will never
Move by themselves
The modes and conditions of the AP and A/THR are
Always displayed on the FMA
How many channel the FCU has
2
The A/THR is linked to
The onside FCU (AP selection)
A selected mode is displayed in what color on the PFD
In blue
A managed mode is indicated on the FCU by
White dashes and a solid white dot
The SPEED mode will control
The pitch in constant thrust situation (climb) and the A/THR in cruise
The crossover altitude is at approximately
23 500 feet
The altitude window is
Never dashed (always displays selected altitude)
When altitude knob is pulled (selected mode) it will
Climb or descent to that altitude and will disregard all altitude constraint and vertical flight plan
When the METRIC ALT is pressed, it is shown in
The permanent data display of the ECAM SD
When you push the VS-FPA selector, it commands a
Level off
To engage the managed mode for vertical operation is by
Pressing the ALT selector knob
The APPR pb is use to arm or engage an approach, which was selected in
The FMS F-PLN page
The ALT button is used for
Commanding an immediate level off
For autoland, the 2 AP are used, what must be green to arm both AP
The APPR pb
The A/THR is auto armed when
TO power is set
The AP can be engaged when
Above 100 feet AGL all the way to autoland rollout
The red pushbutton on the sidestick and thrust levers is called
Instinctive Disconnect
The red pushbutton is used for
Disconnect the AP or if AP off, takeover control of the other sidestick
The AP cavalry charge self cancel after
1.5 sec
The Master Warning/Caution self cancel after
3 sec
The ECAM memo self cancel after
9 sec
If AP disc through A/THR there is only
A single chime
The other means of AP disconnect are
AP failure, pressing AP pb, override on sidestick or rudder pedal
What does this indication means on the FMA (1FD-)
FD 1 is on and FD 2 is off
During TO and landing, the roll guidance is replaced by
A yaw bar index
The FMA has temporary white box when
A mode is changed and stays for 10 sec
A box appears around FD for 10 sec in case
The FMGC is automatically switch
An engaged mode on FMA appears
Green
The third row of FMA is for
FMA messages
A/THR is not available when
TOGA or FLX thrust is set with 2 eng ops
When A/THR is off, movement provides
A normal operation
What are the 3 detents of the thrust levers
CL, FLX/MCT and TOGA
A/THR is not available at ____ or below
Idle
A/THR can be
ON, ARMED or OFF
A reminder to put TL in CL detent is
An indication on FMA ‘‘LVR CLB’’
A/THR can be used in the FLX/MCT detent when
Only 1 eng operating
At cruise, the A/THR will switch to
SPEED mode
At 20ft AGL, what call is made on landing
RETARD to put TL at idle
If the instinctive disconnect on A/THR is pressed for more than 15 sec
The A/THR is inhibited for the rest of the flight
If the A/THR button on FCU is pressed, it will give
An indication of an unvoluntary A/THR disconnect
