Current BGA teaching is now:-
Takeoff:-
Controls
Ballast
Straps
Instruments
Flaps
Trim
Canopy
Brakes (airbrakes)
Eventualities (i.e if the cable / tow rope breaks where do you go?)
Landing:-
Undercarriage
Speed
Trim
Airbrakes (unlocked)
Landing (area clear?)
Lookout
I suppose though if you do regularly fly a flapped machine the addition of an F for flaps between U & S would be a good idea.
Only thing I would say is that as the 'E' for eventualities is a fairly recent addition to the pre-take off checks, ommitiing it from your checks is an almost guaranteed way to have an instructor pull a cable break on you on a check ride!
Hope this helps.
