I have designed a set of gliding airfields for X-Plane recently and thought it would be a challange to fly between two of them in a glider. My choice of route was from Pocklington airfield in the Yorkshire Wolds, to Camphill in the Derbyshire Peaks.
All, of the Navigation points for the flight were found and, apart from not setting the destination ground pressure to reset the altimeter, all went well. Camphill is 1202 feet higher than Pocklington. From a 1000 foot cable launch, thats not bad.
