While staying at the flight school I ask myself, how to orientate oneself in the air. When flying along the airfield traffic pattern or flying in the near of my home base, navigation with a compass or visual positioning does not run into problems. But I wonder, what will happen to any student pilot when absolving cross-country flying.
Certainly, there are aeronautical charts and aeronautical information publication (AIP) to orientate oneself in a sport aircraft. And, contrariwise to the old-school "paper and chart method", there are GPS and air navigation systems, today. In this context the intrinsic question is posed, what charts the famous pioneers and engineers of general aviation, especially the first pilots in history, did use for navigation? The search for historical aeronautical charts and for literature becomes more interesting for me. I guess, I became an aviation historian.
