With the airfield on the Isle Of Wight being on the east of the Island the flight time or routings could be interesting.
Bembridge being the ideal location to depart to Luton would if i am not mistaken would take you over good old Heathrow??
The operation could variy from IFR or VFR conditions could see a wide veriety of routeings and could see a lot of different chock to chock times.
Good luck to this new venture if it can get off the runway.
Sixty Knots single engine control speed (BN2)?? ok
