Can anyone define Threshold?
White Knight, interesting post. I realise I am unsure of some terminology here. What exactly is the definition of Threshold?
I was aware of some sort of 50ft performance data thing, but I assumed that would be based on touching down in the touchdown zone, something that most GA runways dont have. (again, what is the exact definiton of the landing zone)
I was under the impression that the threshold is the beggining of the tarmac, in which case I'd like to see a 747 cross that at 50ft AND touchdown on the numbers... I'm not argueing, merely trying to work it out!
