I put in a call to HSBC in Oxford today and the NetJets cadet loan repayments are £1,115 per month for six years at the current 7.25%. The first repayment is due 3 months after finishing the fATPL at OAT, so the interest that accrues during the training and the deferral is included in the repayment scheme. Having the facts should make the maths a bit simpler.
