Landings within the preceding 90 days.
I apologize for what seems to be a simple question but I'm looking for the FAA's legal interpretation on this to no luck.
How do you ascertain the "preceding" 90 days if I'm flying tomorrow?
Do you:
a. Start counting back from tomorrow? ie. Tomorrow is day one, today is day 2 until you reach 90 days.
b. Do you start counting from today and going back 90 days. Today being day 1 and tomorrow not being counted.
Please advise and if you have a FAA legal interpretation please link it.
Thanks.
