There's cheating and cheating...
The way I was taught to log time was in "decimal hours", rather than hours and minutes - so six minutes = 0.1 = shortest loggable time.
Then, because it's not "flying time" but 'first move with the intention of flight to stopping' - AKA block-to-block time - you add 6 minutes (0.1) to either side of t/o and landing time. That's the way the school charged, so that's what was logged.
So, first solo was 0.3 (18 minutes) and 5 * night full-stop landings were 0.3 each - and I don't fly from Elstree
Those extra 0.2 every flight soon add up. Is that cheating?
