My 'new' EASA-compliant logbook has space to record number of landings. so I do, for each flight. Now, strictly, I can only 'claim' landings where I was 'sole manipulator of the controls'. I can't honestly remember after a day's circuits if I demo'd a landing or not, or how many. What about when after the second bounce, I take over? I depend upon having done at least 3 Trial Lessons in a rolling 90 day period to be legal, so I note everything in the 'Remarks' column. As Whopity says, it might be of value someday, if we lose all our student records for some reason. Fortunately, I've never been asked by the AAIB for info about any of my students, the big school I worked for a few years ago went bust big-time!
