Q

What does it mean when you see the magenta target airspeed triangle above VAPP on approach?

A

Ground Speed Mini has increased speed due to a higher headwind component at your present location than what was calculated at the runway

18
Q

Is this protection available in selected speed?

A

No - managed speed only

19

A

The aircraft has deviated from the FCU selected altitude or flight level by 250 feet

20
Q

When is altitude alerting automatically inhibited in flight?

A

When slats are extended with the landing gear selected down
On approach after glide slope capture
When the landing gear is locked down

21
Q
