if the engines were at idle at 600 feet, were they at idle at 1500 feet? 3000 feet?
Nobody said they were at idle at 600'. They would have been at approach power or close to it.
I know our company indicates that after a long idle descent, we should make sure the engines respond at 3000'. or be spooled up at 1500 feet.
now, we don't have trent engines...but are they so very different?
just wondering, have you ever heard of the above? you seem to think that it is very foreign.
That is very foreign to me. I currently fly B767's with both P&W, and GE engines. I used to fly F28's with Rolls Royce Spey's. I have never heard of anyone doing anything remotely like what you describe. On a piston engine sure, but not a turbine engine. On what engines do you use that procedure?
now if the engines were at normal approach setting at 1500', and they didn't respond (change) when throttles were advanced, there might have been a better chance of making the runway.
we all come from different backgrounds in flying...and we should try to understand the other fellow.
