Bear Cub, the application form is an old one (although the CAA are still sending them out) and like GT I have been crossing out the bits that do not apply. There is no IF requirement whichever way you do it and it can be done as part of your PPL and within the 45 hours (not additional to as it was until recently), the reason being that the PPL requires 25 hours dual and 10 hours solo, the remaining 10 hours, dual or solo, can include training for the night qualification. This is recent information from a CAA representative at an instructor's seminar so I hope Watford agrees.

And yes it would help if they updated the application forms. And reduced the fee if applied for at the same time as the PPL (Hmmm, can't see that one happening somehow). And just out of interest it is possible to take the skill test after the 25 hours dual and 10 hours solo i.e. 35 hours although the remaining 10 hours have to be flown before licence issue.
