Integrated schools seem to pay about £50Kpa or £300 per day for ME IR.
Modular schools £50-60 per hour. The key with these is making sure you get a ground rate for briefings as the PPL '10 minute brief while you walk' doesn't work out for advanced training. Its odd that students don't mind paying £450 per hour for the aircraft but baulk at £50 per hour for ground instruction. Typically you need an hour briefing plus an hour debrief for each trip. Ideally you want to be with the student for a full day at £300 and they perm as many ground/aircraft hours as necessary from you to achieve the training requirement..... But what do I know...?
