The A2A Simulations Community

I think the take home message for me is "it really is okay to cruise around at full throttle, provided you do so at appropriate altitude and lean as recommended." Hi Nick, Yes, that's correct. In principle, one can control the air mass the naturally aspirated engine sucks in at given RPM ...

Well, apparently the service is unavailable due to their server loads so I can't check the thread, but I assume that this is the good old FM made for very purpose to have more realism with default Cessna. It made a real improvement back then, and I used it often. I'd never mix it with Accusim though...

No problem, thank you for taking notice, and to the A2A for making this fine simulation for the very purpose of finding out! :) I'm a little curious about one thing. How uneven is the fuel distribution in this engine? I mean, if we were to lean it out until the leanest cylinder is at peak or lean of...

Hi all, A lengthy post follows, as usual! :mrgreen: I did some test flights to find out some nice cruise settings for A2A Cherokee that I can use in future without having a single look into the graphs. I fully support 'paperless cockpit' and as I've got my charts (or SkyVector) open on my Nexus 7, t...

How about this from Convair NB-36H . A nuclear reactor (which did not actually power the aircraft) was mounted in the aft bomb bay. The reactor was a 1000-kilowatt design weighing 35,000 pounds. The reactor could be removed from the aircraft by a crane while on the ground. A number of large air int...

Well, neither positioning, orientation, dimensions nor that they seem to remain open for flight suggests that they are primarily ammo loading doors (though in field of aviation, it wouldn't surprise me if they had such an additional purpose...). With the photos crownvic posted, they (the two opening...

And as I said: With cut-off or without mixture full rich, my C172 isn't going to start. And in EVERY C172 (reallife) start-up video, the mixture is full rich for engine start. It's a way better as mixture cut-off and then smoothly push to full rich during engine start. But okay, if it's wrong, I do...

-Mixture full rich (about 2-3 seconds, because of overpriming) -Mixture cut-off -Fuel pump off - Mixture >50% -Magnetos to start Wrong again ;) The mixture must be all the way off until the engine catches after starter engagement. Then smoothly push it in to full rich. It's a 'feature' of the Bendi...

Maybe it's a combination of the avgas's higher octane rating and a general misconception regarding octane numbers and performance? Maybe on some cases, or perhaps that aircraft gasoline is just intuitively thought to be a primary choice for an airplane engine. Obviously, sometimes it is just a ques...

The leaded fuel used in airplane engines make a huge difference in how clean they remain. A liquid-cooled Rotax 914 for example is allowed to use both 100LL and regular automotive gasoline. You can clearly see the benefits of unleaded fuel by just looking into the engine - I'm not sure why some folk...

Hi there, Can't really orient on that video by quick looking, but matching to your written description there are at least the entry door and some service panels on that area. To show your own picture, just upload it to dropbox or whatever similar service that allows hot linking to images and copy th...

Yes it totally makes sense as I begin to trade lift for more drag (!!!!). I was curious to see at which point that began to occur as I normally do not come in that slow [...] By design, the approach speeds of typical airplanes are at the high side of the drag polar. If they weren't, the speed contr...

Toward the bottom of the thread, they started talking about automotive vs. aircraft engine technology and someone made a comment to the effect that part of the reason modern automotive engines last longer is because newer, better technology goes into making them. How much truth is there to this? I'...

If I pitched up a tiny bit more until the airspeed reached the very bottom of the green arc, then I saw an increase in sink rate. That's expected as you get below your minimum drag speed - the drag and therefore the sink rate increases with decreasing airspeed. I understand that it takes some rathe...

Yes, I agree with previous posters - making some authentic gauge graphics would really benefit the aesthetics of this little gem.
