muddy waters! thats going to be Jons new nickname..
Just so I'm clear, what if I go and plan an arrival and subsequent departure that all performance calculations say I can do but only just.. Am I gung ho? or is that ok? Because Guru or AGP or whoever you want to use will only tell you if you can do it or no. They don't tell you by how much. You will get a weight limit and thats it - and if the weights ok do we just lob off without any further consideration?
I'm sitting here right now considering the viability of a Global Express into a 4200' airport with climb performance issues because of terrain and temp and I am doing it with both Guru and the AFM because Guru says I can and I want to know by how much. Does it make me gung ho because I'm considering it?
thats a genuine question by the way. I have the feeling that its no longer acceptable to use a manufacturers performance figures for an aircraft - you have to use a fudge factor too...
I might adopt the username gung-ho on here. quite like it.
