Airmanship/CDAs
I never planned on a technical discussion here but:
Max Landing weight of 180T (for ease of figures) in A330 VS1G 145kts.
VLS = 1.23VS1G = 178 kts
Green dot = 1.45VS1G = 210 kts (there is the 30 kts mentioned earlier)
Alpha floor occurs somewhere below VLS.
30 degree turn VS is 1.1 VS level flight (at low speeds the autopilot is usually a bit under 30) so speeds become 160, 195 and 230 respectively.
Therefore at 15kts below Green dot and in a 30 degree turn you are covered wrt VLS not to mention Valpha prot.
Takeoff and final approach speeds are closer to protection speeds and although angles of bank are normally less it doesnt help in case of turbulence.
One logical extension of the argument could be the fuel load...if you dont like the policy of minimum fuel how much extra will you take? Is there a set figure or do you decide on the day? I take extra on some flights and on some others depart with CFP fuel. I know I can fly below Green dot but I dont fly at VLS.
