Hello!

NOTE: I've also posted this in the FS 2002 forum, but thought I'd post it here as well. If this isn't the right thing to do I apologize.

I have a question to ask... I have installed a couple of aircraft that were 'FS 2002/ FS 2004' compatible, and for some reason when I load the sim, the A/C's engine(s) shut down and won't restart. Also, moving the throttle will not increase engine RPM's. Please note that prop trim/ mixture are not affected... the RPM's just won't increase on the tachometer.

Anybody ever come across this? Here is one of the A/C in question:

http://www.flightsim.com/kdl.php?fid=93064

It's a B-17 Shark Fin (although in the description it's called a 'G' Model).

Any help & suggestions are most appreciated!

Thanks!

Alan

change to the Cessna 172 Skyhawk, start the engines, and then hop back into your B17G and everything should be working fine.   When you go to shut down your sim, do not shut off the engines so that the next time you hop in a plane, the engines will be running and everything is ready to just go flying.

Hi Alan. This aircraft appears to be a repaint of Paul Clawson's YB-17 posted here. http://www.simviation.com/fs2004vintage30.htm

It was originally intended for FS9 so I suspect it has FS9 flight dynamics (AIR file & aircraft.cfg). Not sure why the "Redme" with the repaint claims it's suitable for FS2002.

Hello!

Opa & the Captain: Thanks for the replies! They are much appreciated, and it's good to know the flight sim community is here to help a guy out.

Hagar,

Thanks for the reply! As you can see, I just posted my reply to Opa & Capt. Propwash. I will heed your advice, and from this point on will reply from the FS 2002 forum. I just did it here to see if I would get any other responses.

It appears as if there are differences in the .air & .cfg files between FS 9 and FS 8, but damned if I can't figure out what those differences are! Even with programs like AirEd and AirWrench at my disposal, it's difficult to figure out what changes I need to make in order to get the A/C to fly.

I'll keep investigating this, and hopefully I can get it straightened out.

Thanks again for the heads up, and I will continue this discussion in the FS 2002 forum.

This may or may not help you, but it's worth a shot.

There is a setting in the aircraft.cfg of many fs2004 aircraft under the heading of [GeneralEngineData] called "min_throttle_limit", that tells the sim how little throttle there can be before the engines shut down. (If my understanding is correct)

You might try adding this line to the aircraft.cfg of the B17 you want to use:

min_throttle_limit=0.000000

So the aircraft.cfg would the look like this:

[GeneralEngineData]

//0=Piston, 1=Jet, 2=None, 3=Helo-Turbine, 4=Rocket, 5=Turboprop
engine_type = 0
fuel_flow_scalar = 1.000000
min_throttle_limit = 0.100000
engine.0 = 10.10, -10.58, 0,
engine.1 = 10.10, 9.81, 0,
engine.2 = 8.83, -20.81, 1,
engine.3 = 8.36, 21.27, 1,
min_throttle_limit=0.000000

While I don't think it's nessesary for FS2004 to have this entry present, most aircraft do. (I also think FS2002 will ignore this entry, so you shouldn't have a problem cross compatability there either.)

Like I said, it may be worth a shot.
