If not otherwise specified, what is the minimum OE GA gradient?
2.5%
Can you use GRF on the ground
It is for in flight landing performance.
It can also be used for take off performance if “downgraded” by the airport
Stable criteria for circling app

landing config
Correct lateral and vertical flight path
Vapp +10/-5
Max 15 deg bank within +-30 deg final track
Landing cx completed
When does FCOM SP 51 list of required equipment for rnp ar is valid to?
To the IAF
What protection do you have in altn law?
Low and high speed stability and g protection
What tools do we have when we are performance limited?
On A320, have an aft CG. Shift pax or cargo. Consider flap 3 /toga. Ask for wind favourable runway. Liaise with icc
