What does each column mean on the PFD?
A/THR | VERTICAL | LATERAL | APPROACH CAPABILIY, DH/MDA | AP, FD, A/THR ENGAGEMENT STATUS
How is the crew made aware of mode changes on the FMA?
A white box is temporarily displayed around the new indication
How are armed modes displayed on the FMA?
- Blue – armed
- Magenta – armed because of a constraint
- Green - engaged
When is the side stick position indication icon (white cross) displayed?
- Displayed when the first engine is started
* Disappears at liftoff
What does side stick position indication icon indicate?
Summed side stick inputs
What would large red arrowheads indicate?
Pitch attitude of +30°
After you input the destination and ILS information into the MCDU, what do you check for?
- After the ILS pb is pressed, green light
- ILS frequency and course on PFD
- ILS identifier once identified
- LOC and GS scales displayed on PFD
What does MAN PITCH TRIM ONLY in red mean?
You are in Mechanical Backup.
What does USE MANUAL PITCH TRIM in amber mean?
You are in Direct Law
What are the pitch and roll angle limits indicated by the green = signs?
- Pitch: +30° up/-15° down
* Roll: +/- 67°
How can you determine you are in Alternate Law?
- Amber x’s at the pitch (30° UP/15° DN) and bank (67°) limits
- Only Vls and Vsw is displayed on the airspeed scale
When would the sideslip index change from yellow to blue?
In case of an engine failure during takeoff/go-around, it becomes a blue beta target
What does the yellow speed trend line on the airspeed display indicate?
The speed the aircraft will reach in 10 seconds if acceleration/deceleration remains constant
What is the difference between the magenta and blue target airspeeds?
- Magenta – Managed speed computed by the FMGC
* Blue – Selected speed on the FCU
What is VLS and how is it displayed?
- Represents lowest selectable speed providing an appropriate margin to the stall speed
- Defined by the top of the amber strip along the airspeed scale
- In approach mode is equivalent to VREF
