QRH REV 42
FCOM 3.04.10 REV 24
Both apply to same SN, same model
My copy of the FCOM only says :
VAPP = VLS + wind correction.
The wind correction is limited to a minimum of 5 knots and a maximum of 15
knots.
The flight crew may modify VAPP through the MCDU.
– During autoland or when A/THR is on or in case of ice accretion or gusty
crosswind greater than 20 knots, VAPP must not be lower than VLS + 5
knots.
It does not say Vapp = VLS + wind correction + 5 knots.
My copy of the QRH says :
Vapp = MAX (Vls +5 , Vls + wind correction)
Vls + 5 knot only if autothrust is used or autoland
wind correction = 1/3 headwind
It does not say Vapp (2) = VLS + 5kt (1) + WIND CORR .
It has got 2 options :
- Vls + 5 (+ 5 if auto-thrust)
- Vls + wind correction
whichever is greater.
I am confused about the FCOM statement
+ wind correction" minimum of 5 knots.
That this mean :
a - you always add a minimum of 5 knots for wind correction ? (wind or no wind)
or
b - you only add the 5 knot minimum wind correction only if any wind ?
I interpret the FCOM that you always must apply a min 5 knot wind correction, from the statement
The wind correction is limited to a minimum of 5 knots
However I interpret the QRH as saying you don't need the + 5 knots if no wind and no auto-thrust.
