Flight envelope violation

[David Williams]

Flight envelope recommend 4000m, I fly near 5000M.

This is flight envelope of micro jet engine installed on man aircraft. At what maximum altitude can we fly ie 4500 meter given and my requirements is 5000 meter. ?
What point to be considered during flying!?

@Mid7night - You have any input here, Ben?

During flight you have airspeed which offers a cumulative affect on thrust. Flying on a cold high pressure day is more or less like flying 1000 ft lower.

Stuff to consider: weather aloft, absolute temperatures, absolute flying weight, fuel burn to get there, glide power off back down , how badly are you breaking the rules

Sure.
Good suggestion, as air density, Pressure ration at 5000m is lower and O2 levels is 50% less to the Ground.
