I know from You Tube that the T6 HATES negative G situations. I try to avoid them at all cost. I've looked on the forum about this but haven't found anything. The question is, if I get into one of these unfortunate situation, how do I get a restart? Oh and one more thing how do I get into the rear cockpit, should I ever get good enough to fly from there. LOL. Love this plane! Thanks

Can't help you on #1, hasn't happened to me yet. On #2, I just move my eyepoint straight back until I'm over the rear seat. I love it back there.

to get to the rear seat in FSX you'd simply right click on the screen, select "Cockpit" and "Rear Seat". I've done a few negative G maneuvers, and she normally catches pretty quick. I'm not to scared about that....the landings however is still an experience...

You don't want to be doing ANY sustained negative maneuvers in a T6. You will get -1g during a well executed slow roll but that's about all the negative g you want to be pulling in this airplane.
If you DO get into a negative g situation in the T6 the proper way to recover the airplane is to roll it to the nearest horizon to regain positive g. When the carb "feels" the positive g the engine should catch and recover.

Typically an engine that is starved from fuel does not need to be re-started, as it is never stopped! As your forward airspeed turns the engine, everything keeps on going: sparks firing, pumps and generator turning and even the propeller governing when the speed is sufficient. Just re-introduce fuel, and you're back in business. This doesn't only apply to negative-g recovery, but to any reason of fuel starvation, such as running a tank dry.

The default fs A key will cycle your view within a given set. So within the virtual cockpit the default A key will cycle your virtual cockpit views.

thanks,
Lewis

I,m still having trouble with my engine quitting. This last time I just pushed the nose over to gain airspeed, not much at all. As soon as I did the engine started to wind mill, no power. Had to do a forced landing. That went ok but I couldn't get it started after that. Is anybody having the same thing???

Are you sure you have the latest update: viewtopic.php?f=129&t=57819

You'll need this even if you just bought the T6. When the T6 was released, there was a bug that made it impossible to restart, the update will take care of that bug.

Larry,

Along with being starved of fuel, another thing that'll cause the engine to quit in short order is being starved of air.

If you're flying the T-6 through cloud, rain or hazy weather, the carb heat lever could be your salvation. It's important to understand that carburettor icing isn't just a 'cold weather' phenomenon either.

Do you recall what the weather was like when you experienced the engine failure?

Thanks,
Nick

I have not updated the T6 yet. As far a the weather goes sunny perfect temp, nice day. I'll try both suggestions. I might have to change something in the config file.

Ideal carb icing conditions are near 70F on a humid day. The temp drop in the throat of the carburetor can easily reach 40F. That puts the temp right at freezing and will cause the water to condense out of the air and ice crystals to form.

Please do not change anything in the config file, this is not the ordinary addon, Accu-Sim may respond badly if you edit this file.

I suggest you do NOT do any editing in any A2A cfg file. A2A planes are not like other add ons and changing anything in the cfg files can really screw things up for you.
I'm fairly convinced that if you install the latest update this will fix the problem if the problem is NOT related to normal T6 behavior when subjected to negative g flight.
After installing the update if you experience negative g just roll it out to the nearest horizon to regain positive g which the engine requires for normal flight.

As was mentioned above, there was a problem with the engine being unable to restart which was fixed pretty quickly with an update, within a day or two of release if I recall. Running the updater should take care of it. I don't think I've seen anybody mention it still happening since last spring.

Thank you Thank you all. The update did the trick. Now I just have to get better flying the thing.
Thanks again LB
