Flaps 30 vref30
Flaps Manoeuvering Speed guarantee…
… at least full manoeuvering capability or at least 40 degree (25 + 15 overshoot) to stick shaker within a few thousand feed of airport altitude. While the flaps may be extended up to 20.000 ft, less manoeuvere margin to stick shaker exists for a fixed speed as altitude increases.
Minimum Manoeuvering Speeds
Flaps Down Amber Band
Top of amber band: full Manoeuvre speed (1.3 g or 40 degree bank) to stick shaker. Does not vary with G load, based on current air speed and angle of attack
Middle of amber band: decreased manoeuvre speed (1 g or 30 degree bank (15+15))
Bottom of amber band: stick shaker depending on current g load
Minimum Manoeuvering Speeds
Flaps Up Amber Band
Up to 10.000ft: like flaps down
Between 10.000ft - 20.000ft: adequte manoeuvre capability
Above 20.000ft: 1.3 g manoeuvre capability to low speed buffet
Command speed landing
A/T on: vref+5
A/T on gusty wind: vref+10
A/T off: vref+5 plus 1/2 HW plus full gust

Vref
V2 provides at least 30 degree bank capability (15 + 15).
Descend rate at low altitude
Above 3000 ft: 50% of alt
3000 - 1000 ft: 1500 ft/min
Below 1000 ft: 1000 ft/min
