I am bit confused about how to determine Vapp, in particular in these conditons :
- no ice accretion
- no auto-thrust
- no autoland
- nil wind
- normal conditions (ie. no failures)
FCOM 3.04.10 (operating speeds definitions) says :
VAPP = VLS + wind correction.
The wind correction is limited to a minimum of 5 knots and a maximum of 15
knots.
However, in the QRH 4.00 (Vapp Determination) it says :
Vapp = MAX (Vls +5 , Vls + wind correction)
Vls + 5 knot only if autothrust is used or autoland
wind correction = 1/3 headwind
So, according to the QRH, in the above conditions, Vapp = Vls ?
However FCOM says Vapp = Vls + 5 (minimum) ?
Now do we add the extra 5 knots to Vls (in the specified conditions) or not ?
Doesn't the QRH contradict or the FCOM or I can't read ?
