Re: Advice on Manston to Sunderland trip
Take a good look at the flight manual and make sure that you know the correct RPM for cruise at altitude and how to lean the engine for best performance.
Climb above FL50 when clear of Class A airspace and enjoy a "no stress" flight with good radar cover, good range from the nav aids and very little other traffic because most of private GA never ventures above 2400 ft ALT.
