Title: BAE146-300QT Model / Behavior problem
Post by: EHM-1945 Christophe on October 13, 2006, 09:49:07 am
Dear EuroCargo Pilots,

Yesterday, I've experiecend my first crash with ProPilot :{

I was supposed to do LDZA (Zagreb) to LHBP (Budapest) trip (C172) using a BAE 146 plane. I was using FS Passenger as well and setup some cargo load (around 5000 pounds front and same for rear). My overall load, including fuel was 50% of total capacity, knowing that LDZA to LHBP is 45 minutes flight. Everything was ok, up to the point I take-off. After passing V2, I tried to level up the bird, having the nose leveled up at 15 degrees, having the flaps set at 24, but nothing happened and the plane stayed on the rwy.... Then I deciced to brake (even if after passing V2), and then I hit a small hill, and then ends up with a crash (and a suspension then :'(

I'm using the BAE146 downloaded from the Fleet page,  and I'm using the BAE146 Panel, downloaded from BAE Panel Project Page (v3 and patched with v3.1 update). Coming along with the panel, there is a number of .air files. I would like to know which one you are using, and if the BAE beahvior is correct on your side. Which MODEL file are you using as well ?

Thank you in advance for any feedback you can provide me

Cheers

How was the Center of gravity, and now matter what the stuation after passing V1 you are commited to take-off no matter what the situation.
Did you trim the aircraft for takeoff??

Christian,

The trim was set for Take off and the CG was middle. So should have been normal. I agree that after V1 you take-off whatever happen. But in that case, rear wheels were sticked on the runway.  By the way, when I redo the flight (without ProPilot as I'm now suspended), and without FsP, with Cargo Load = 0, then I was able to takeoff normally as I was expecting it previously.

Hi Christophe,

It's a bad idea ;D to test the airplanes on ProPilot ;D .

I think you should first test it out on a sigle flight before using it.

You are completely right. This is the first and last time I do this, believe me. I don't want to crash the all EuroHarmony fleet ;D;D

I do not know those panels, but as I mentioned before, panels can totally alter the flight dynamics sometimes. Once I discovered similar thing with an Airbus A330 panel :s

Roberto, thank you for the input. I'll check on that side of the problem. I will check if the panel could be partly the cause of my problem.

Christophe,

I use the 'baepanelproject' panels (both BAe 146 and Avro ARJ) and find them excellent. However, to ensure proper flight behaviour you must follow the installation instructions contained in the manual... Have you read through this section? It sets out what all the air files are for - the panel is designed to work with all the commonly available BAe 146 models and Matthias (the designer) has included an airfile and aircraft cfg file for each one to ensure it performs as expected.

So if in doubt, I'd say reinstall the plane and panel as indicated in the manual and you should have no problems.

Also, it's an excellent panel but you have to ensure you follow the checklist as the hydraulics etc are very realistically designed so your control surfaces won't work if the hydraulic pumps are off (just as an example). Worth checking visually that the elevator moves as commanded before you leave the stand... This is the main thing I can think of that would stop your aircraft rotating when you tried to take off.

Let me know how you get on. Good luck!

Dominic,

Thank you for this information. I've installed the panel using the manual and I'm following the checklist coming along. In fact this panel is quite good, even if the graphics are a bit old compare to some other recent panels. Anyway, I think my problem is coming from the FsP Payload file. I tried to flight the bird without FsP (Anyway, flying cargo with FsP is useless), and I had no more problem.

Thank you to everybody for your inputs and help

Cheers
Kristoff
