The one I was taught went B-U-M-F-F-G-G-H-C
Brakes off
U/C down - it was down and welded to begin with!
Mixture rich
Fuel - sufficient / tank selected
Fuel pump on
Gyros syncronised
Guages - all green
Hatches and harnesses
Crew - all happy?
Later on in the JP the mantra was.....
speed below 140
airbrakes in
u/c down
fuel sufficient for 90 (95) kt threshold speed
flaps to take off (limit was 150 kts ISTR)
hydraulics - brakes on/off pressure good, confirm exhausted on release
hatches and harnesses - checked
Amazing really what a young brain can soak up - the first solo was nearly 30 years ago in the dear old Mk.3 .....happy days!
