reference hours Building
Flying For Fun: these are my reference: JAR FCL1 (155) and LASORS + numerous appendices, IEM, AMC of JAR FCL 1.
I have never doubted that flying solo helps for decision making. But the training integrated or modular is ruled by the JAR FCL. There are some specific training which have to be done ... I will not argue any more. Flying For Fun notices that I have 12000 hours of flight in a major airline, so a certain knowledge of what is required to succeed to enter in Airlines... Do not loose your time if your aim is to become a professional pilot
Just an advice of an old flyer.
