Hi to all, I've this problem: when i fly in cruise speed ( i've tried at 15.000 and 20.000 feet) the ADI show 2 or 3% up respect the horizon; in external view the airplain is not parrallel on the ground; the Automatic pilot is in ON in my desiderate altitude and when i grow the speed until the limit (after is dangerous) the ADI sign 1% up. This is strange because in the other airplane when arrive at the desiderate altitude with autopilot and after fly in cruise speed, the ADI show 0% and the airplain (in external view) is in correct position, parallel on the ground.
How can I correct this? Is possible to fly in correct position like the others airplane?
Many thanks for your help.

I'm not sure if I'm understanding you correctly .... but .... In AP controlled flight .... with ALT HLD selected "ON" .... if you fly too fast then it might cause the nose to come down .... and you would therefore likely see a "0" degree attitude indication per the ADI. If you do not fly so fast then it is possible the nose might rise a few degrees .... and you would therefore likely see anything from a "1-2" degree attitude indication per the ADI. Unfortunately I'm still not sufficiently competent with regard to the proper handling this aircraft myself yet in order to be able to comment intelligently It's an open forum though If anyone else wants to comment accordingly .... then please feel free to do so Mark C AKL/NZ

Hi Mark, in fact I dont't want to fly at maximum speed for lower degrees about Adi; this is a problem when I slow down for landing that the airplane have an angle respect the terrain too high (repect all the others airplane). I supposed that the problem was about CG in aircraft.cfg, i've tried to change the value so to move the CG more in central of plane but nothing changed. I've tried also to change the heavy about fuel and passengers always about CG; like above the CG chenges but not the problem during the fly. It seems that the airplane, for fly linear (parralel of terrain, ADI at 0 degree) need maximum speed during all trip. It's very strange.

OK amico ! I'm still not sure if I'm interpreting you correctly .... but .... the BAe 146 & ARJ aircraft should all approach (with flaps extended) showing the nose a few degrees "down". "IF" you are seeing a nose down attitude during approach like this .... .... or like this .... .... then that is pefectly normal/correct ! I presume you are using the ARNZ/HJG supplied Aircraft Base Pack and FDE available from this website only. Thanks to Mike MONCE, our FDE is different/more authentic than any other version currently available elsewhere. Mark C AKL/NZ

You seem to think you have a problem because it handles different from other aeroplanes In the cruise at altitude a lot of aircraft fly nose up.especially at altitude as it helps maintain lift in the thinner air. From the outside this aircraft will not be parallel to the ground but be nose up a degree or two This is what you are seeing and that is what is being shown on the panel As Mark point out full flap will make it nose down. Why do you expect it to be like other aeroplanes? It is a high wing high lift aircraft......why would it behave like, say a Boeing 737?? This is a BAe 146 set up to fly like a BAe 146 You should not be moving the CG on the CFG.....that will only get you in a mess The CG will be correct I can't really see what your problem is.....it is behaving for you as it should Garry

Garry, my ask was a curiosity for understand if the plain is so or if i wrong something (or something wrong in my setting)!!!
Don't worry please, I like this plane specially the panel that is wonderful.
Bye.

I haven't checked in here for a few days so a bit late on this thread. The plane should be in a 1-2 degree nose up attitude in cruise, which is usually around 260-270 IAS. This is fairly normal in most airliners. Sit at the back of a real airliner on your next flight and in cruise you will note you can see "up" the aisle. The pitch will change with IAS: lower speed higher AOA, higher speed lower AOA; just the physics of lift. The 146 is a different in its approach attitude in that the flaps do generate more lift than "normal", hence the slight nose down attitude that Mark shows. If the nose is too high on approach then you are flying too slow. If you follow Vref+10 closely for the current weight of the plane, you should get what is shown above in the screeshots. Try to hit Vref on crossing the threshold and you should end up with a "greaser". Mike
