Good day,
Having found the following video that demonstrates takeoff roll (
http://www.youtube.com/watch?v=925Mg...ayer_embedded#! ) with upper surface of the wing covered by snow and possibly ice, I would like to ask for your opinion whether such a takeoff is a violation of FCOM procedures.
The details are as follows:
Aircraft type A320-214
METARs preceding to takeoff (in ascending order, takeoff took place at about 13-14Z):

1. Specifically, I would like you to clarify that the violation of the following procedure took place:
FCOM A319-320-321 SUPPLEMENTARY PROCEDURES - ADVERSE WEATHER - COLD WEATHER:
EXTERIOR EXPECTION
[...]
SURFACES....CHECKED FREE OF FROST, ICE AND SNOW
All surfaces of the aircraft (critical surfaces : leading edges and upper surfaces of wings, vertical and horizontal stabilizers, all control surfaces, slats and flaps) must be clear of snow, frost and ice for takeoff.
2. Also, could you please clarify whether it is permitted to takeoff with contaminated upper surface of the wing assuming that contamination (snow in this example, with a possibility of ice) will be blown off during takeoff roll.
For me, violation is clear. I would like to hear opinion of other pilots of Airbus and ground personnel. Please do not refer to your "company procedures" though, I'm more interested in common procedures set by Airbus.
