Genuine question, what manoeuvre margin exists at the f and S? it's defined for VLS,but I haven't come across any definition for manoeuvre margin for f and s.
17th Performance and Operations Conference in Dubai explains this topic in detail. Extract below:
Maneuvering capability
At V2, one engine out:
Stabilized turn at 30 bank before alpha max
At V2 + 10, all engines operative:
Stabilized turn at 40 before alpha floor
At Green Dot:
Stabilized turn at 45 bank before alpha prot
At Vls (final takeoff up to landing) :
Stabilized turn at 40 bank before alpha floor
With AP on you won't use these bank angles nor for that matter in manual flight.

Affirm LHRPony, on takeoff they are retraction speeds. The same part of the FCOM also defines F and S speeds are target speeds for the approach.

And thanks too vilas for sharing.
