When do you HAVE to produce a NOTAM
We're looking at having a fly-in next year, and my understanding is that a NOTAM is professional (and nice to see!), but is not a legal requirement. We've asked for them to be issued in the past on that basis, no problems.
BUT, someone is now telling me that it's a legal requirement. We're doing it anyway, but I'd be interested to know. The example given was kite-flying (their experience), so (in the UK for ease) is there a minimum height AGL (for any activity) over which you must ask for a NOTAM to be promulgated?
Intrigued!
