OK, and copied. So "Flugbuch" is the logbook ... and the “Leistungsbuch” (
power book, according to Google Translate) is what? A bit more elaboration on that aspect would be good, as it doesn't seem to have been a feature in my [brief] Mil flying career... or indeed mentioned here before. It sounds very interesting.
BTW, it's your turn to wash up already. Just saying.
