I get this
This question is not about whether you have to land or not. Its about an argument/ego battle between some pilots who work at competing flight schools.
Now here is the real answer. land your damn aircraft and don't worry about what aaanybody else is doing. Who TF cares what the real definition of land is? If there is any question in your mind about what it means or what you are supposed to do, land, touch down, plant the sucker, slide er on, kiss mother earth.
Here let me help you with this: FAA/EASA/ or whoever you fall under inspector asks, "did you LAND at all of these airports?" If you actually landed then you can answer calmly and confidently, "YES", and no one can or will ever question you further. There will be no video or eyewitness testimony that can ever contradict your answer and you can pass a lie detector test. AND, no one will ever be able to challenge your judgement on this issue because the regs say to "land" and that is exactly what you did! You don't have to worry about how anyone else accomplished this lofty goal. All you need to worry your pretty little head about is that you did it absolutely and unequivocally correct.
It ain't brain surgery, that's why you don't have to be a brain surgeon to do it.
Hope that helps.
