PRIMARY FLIGHT DISPLAY
Q: How can you determine you are in Alternate Law?
Ref: (FOM VOL. III-DSC-27-20-20)
- Amber X’s replace the green = marks at the pitch and bank limits
- Only VLS and VSW is displayed on the airspeed scale
PRIMARY FLIGHT DISPLAY
Q: When would the sideslip index change from yellow to blue?
Ref: (FOM VOL. III-DSC-31-40)
In case of an engine failure during takeoff/go-around, it is now a blue beta target
PRIMARY FLIGHT DISPLAY
Q: What does the yellow speed trend line on the airspeed display indicate?
Ref: (FOM VOL. III-DSC-31-40)
The speed the aircraft will reach in 10 seconds if acceleration/deceleration remains constant
PRIMARY FLIGHT DISPLAY
Q: What is the difference between the magenta and blue target airspeeds?
Ref: (FOM VOL. III-DSC-31-40)
- Magenta – Managed speed computed by the FMGC
- Blue – Selected speed on the FCU
PRIMARY FLIGHT DISPLAY
Q: What is VLS and how is it displayed?
Ref: (FOM VOL. III-DSC-31-40)
- 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
PRIMARY FLIGHT DISPLAY
Q: What speed does VMAX represent and how is it displayed?
Ref: (FOM VOL. III-DSC-31-40)
- It is the lowest of VMO/MMO, VLE, or VFE
- Defined by the bottom of a red and black strip along the speed scale.
Q: What is Green Dot speed?
Ref: (FOM VOL. III-DSC-31-40)
- Engine out operating speed in clean configuration
- Appears when the aircraft is in the clean configuration
- Corresponds to the best lift-to-drag ratio
