Since commencing my PPL last October I've done 55 hours, the last 7 of which have been since getting my licence.
In future I reckon to on about 70 hours per year - it would be more than that if I could afford it but the great attraction of getting the PPL is the chance to visit and fly in other countries.
At the moment, with the help of some fellow Prooners I'm planning a trip to RSA in April which should result in 40 odd hours in two weeks, give or take but at £35 per hour it is very cheap. The places I'm planning to visit should be fantastic and now that Mrs.Sennadog is happy with flying (quite like the bumps yesterday but wasn't keen on inadvertently flying into cloud) it will make it far easier on the persuasion front.
