GB flaps protocol.
What are generally used for take offs and landings?
1 + F seems to be most airlines choice (?) but, a littly birdy tells me GB use 2???
Landings I understood FULL, unless high wind conditions (whatever the cut off figure is from 3 to FULL for wind speed?) to stop you floating?
Please drown me with your superiority & knowledge.

Airbus Flaps
The A320 family takes-off with a flap setting of 1+F, 2 or 3! This is dependent on the field performance (i.e. TORA, ASDA etc.). Every performance page for each airport/runway states quite clearly the flap setting that the performance figures are predicated on.
That is Airbus SOP. I can't speak for GB but very much doubt that they will do anything vastly different to what Airbus recommend (if at all!).
Hope this helps...

(BA) We used to use paper Perf Manuals that basically used 1+F everywhere, except when field limited e.g. ABZ... then F3 used.
We now use some electronic gizmo called CARD via ACARS. This uses a random number generator for Flaps and Speeds, seemingly totally unrelated to weather or runway length. It is quite happy using speeds ~120K and F3 from LHR on a nice day (A319 - and include a 5K V1/R split!), and 1+F and 150K+ on a wet runway somewhere more limiting...
It basically tries to get the best (highest) Flex Temp, and presumably is "random" since it cannot understand rounding errors in it's calculations, nor take into Flap / Tyre wear, or having your fillings fall out at LIS at 155K when it would quite happily fly at 135K...
