I realise that many readers of this paper know more about private flying than I do; on the other hand, many may not be so experienced or have even flown. I have tried to put in things of interest to both and hope I shall be forgiven if I have put in too much elementary detail, or that my simple suggestions appear childish. I find that often it is the small and simple things which go to make for safety, comfort, and efficiency. I have no technical knowledge other than that gained by sitting behind internal combustion engines, which I have done during a great part of the last twenty years.
