Unless QF is different the L/E flaps will run with pneumatics if it is available.
The classic also, with alternate T/E selected; if pnematics are available the L/E flaps will run when the T/E flaps are not up.
The sequence is; Group A flaps 6 thro' 21 when the T/E is approx 1/4 degree, the remaining flaps Group B will extend as soon as the flap lever is moved from 1 to 5 units.
Hope that helps.......
