hi, i adjusted the setting you mentioned in the other post related to changing the thrust setting mark, and i also figured out my trim setting wasn't right.

its marked on the pitch (lol) in green that the trim should be on 5 at take off.

so, by changing that taking off went a lot easier, but.. when in flight, what should be the normal trim?

Just an update.

I did two flights from YPDN (Darwin NT) - YPPH (Perth WA). Here is how it went:

Aircraft setting. CS727-200 Ansett. GW 175250. 155 passengers, 10 cargo pallets @ 700lbs ea. 70% fuel (Left 100%, Center 43.8%, Right 100%).

With an engine thrust rating of 17400
171500 FL330 still climbing at 300 knots 1200 fpm
171300 FL350 still climbing at 280 knots 1000 fpm
170650 FL370 still climbing at 270 knots  700 fpm (Altitude Hold switched on)

With an engine thrust rating of 15500
170500 FL300 still climbing at 300 knots  500 fpm
169900 FL320 still climbing at 300 knots  500 fpm
169300 FL340 still climbing at 280 knots  300 fpm (Altitude Hold switched on) both the Airspeed and VS were starting to drop significantly. She was struggling to climb any higher.

I think there is enough of an improvement for me to stay with the 17400lbs thrust.

Hi Edwin.

As you can see, the extra thrust gives the 727-200 enough power to fly at a higher altitude than with the ones listed in the default aircraft.cfg. I honestly don't remember the difference being that much. I had to do the same flight under the same conditions but with just the different engine thrust. I never did that before.
