How to PROPERLY trim a medium jet aircraft
Hi flight testers,
I'm having a little issue on day to day operations on medium jets as to how correctly and properly trim a medium jet. I say medium jet because that is my actual work-horse but in general I'm referring to a swept wing jet aircraft with powered controls.
A long time ago an ex test-pilot on light aircraft (Piper) told me this:
You start with the rudder trim in order not to sideslip the aircraft. Once it flies straight and tends to roll you may apply a bit of aileron trim.
This also worked out nicely on the ATR turboprop and in cruise flight a gain or loss of 1 - 3 knots could be observed between a good trim and a poor trim. (Not talking about loading here).
Anybody a good insight into how to properly trim a swept wing jet and why?
Thanks for your insights.
