R66 TR in Switzerland
Here's a breakdown of the cost in Switzerland (mountainflyers.ch) for comparison.
Ground course: 260 CHF (this price is of course for a course with a group of people, one full day)
Flight time: 1360 CHF /hr of actual flight time w/instructor, including 1 landing fee (-> 1225 CHF per rotor-turning hour if you assume 6min for startup/shutdown). Also, the instructors part of 150 CHF is not charged on the checkride flight.
FOCA examiner: 230 CHF
No VAT levied on training
So for 5hrs RTT training + 1hr RTT checkride, it would add up to:
260 + 5*1225 + 1075 + 230 = 7690 CHF
With the current exchange rate, this would correspond to 5.000 GBP.
