Nose Pitched high in straight and level flight!!

Hello Fellow Aviator's,

I was wondering if anyone could advise me on how I should go about fixing this problem.

I'm currently flying a Metroliner 23, At cruise altitude and speed, the aircraft is pitched up at the nose at about 15 degrees. Cruise speed is 0.52 mach and cannot increase the speed thinking it will lower the nose.

In spot plane view it looks very un-realistic.

On late final, it is almost impossible to land when you can't see the runway.

Is there anyway of changing the CoG of the aircraft , or is their any suggestions on how I can fix this.

Thanks in advance

Did you try trimmming?

Num pad 1 to trim the elevator up (if the nose wants to go down)
Num pad 7 to trim the elevator down (if the nose wants to go up)
Hope it works.

Look in aircraft.cfg. If there isn't a section like the following, put it in

[flight_tuning]
cruise_lift_scalar=1.0
parasite_drag_scalar=1.0
induced_drag_scalar=1.0
elevator_effectiveness=1.0
aileron_effectiveness=1.0
rudder_effectiveness=1.0
pitch_stability=1.0
roll_stability=1.0
yaw_stability=1.0
elevator_trim_effectiveness=1.0
aileron_trim_effectiveness=1.0
rudder_trim_effectiveness=1.0

Then try increasing the cruise_lift_scalar by 0.1 or 0.2 at a time


BTW

Each time you change it, save the file then go to 'select aircraft', select another aircraft in the  window only, don't actually click on OK, then return to your original plane. That way the chagge is picked up by the prog.

Start by increasing it to say 1.4, you'll find the aircraft will try to climb, so you'll have to trim nose down to stop it - problem solved

I experienced the same thing a few times when "flying" late into the midnight oil! In my case I had left the flap setting at take off position! Yes, even the best of us (haw haw ;D) Nice to be able to just close things down and jump into bed ain't it!
