Description

I think ace developpers have forgot one small thing, the sonic boom when a supersonic plane make a flyby over us. And if you add it, please don't forgot the whole sound effect, for example, if a supersonic jet make a flyby over our head, we can't hear the sound until the plane is right over our head.

And other thing, I heard about that more a plane is high in altitude faster they can go.

Thanks!

History

  • Subject changed from Suggestion for ACE for OA. to Aircraft supersonic booms

Mach 1 at 1000m is more than 1200km/h.
Considering how low the operating altitude of aircraft is and how slow they are, that happens so rarely in this game that IMO it's not worth implementing.

Making planes go faster at altitude isn't possible in the game I think, and you'd have to go way higher than is practical in-game as well.

At the low operating altitudes that Arma2 forces us into, Sonic boom pressure would be devastating to some of the shacks we encounter in chern and taki. Doors blown off hinges, windows blown out of frames, and quite a few deaf guys.

Supersonic flight would really only benefit certain jets such as the F-16 and F-22/F-35 which are designed with Negative static stability in mind. But these kinds of advanced flight dynamics simply can't be employed in Arma 2's primitive flight engine, and are therefore totally ignored so as to focus on the small map ground attack capabilities. And in addition, attack speeds at mach>= are totally useless due to the fact that we're forced into such a low altitude ceiling, so that firing missiles while at high speeds is useless due to every possible tree and building on the map being right in the middle of our attack angle.

Should Arma 3 enable us to fly at 10,000+ ceilings over hundreds of nmi, this would be an awesome feature. But in Arma 2, no one would ever see it.

Edit: Oh, and btw; at supersonic speeds, you wouldn't hear the jet until it's quite a bit past you. Reason being is that the Mach cone at Mach+ angles at roughly a 45 degrees. So you're looking at the plane being a few hundred meters past you at low altitude and quite a bit further at higher altitude.

A jet has to be REALLY low to do even slight damage to a window. See the mythbusters episode.

Is there a restrictive height ceiling in Arma, by the way? Or is it just the view distance and lack of FCS that pushes peoples so low?

You mean the mythbusters episode demonstrating the capability of a sonic boom blowing doors off hinges, lights off ceilings, and windows out of their frames? I'm not saying that it's not implausible considering the circumstances, because it is. But I am saying... that this is the second thread now that you've entered just to seemingly, pointlessly, and unsuccessfully refute the things I post.

And afaik, I haven't reached a real restrictive ceiling in arma. But yes, the view distance is what forces pilots to low altitudes. At 2500m for instance, even at 10k draw distance, pop in effect is considerable. So while you may have a lock on a target that's 5-6 km away at 2500m alt, you have no idea how effective your angle of attack is because you can't see buildings, trees, etc around the target. In fact, all you really see is a green box with a circle if it's locked. If you were to stay at the same altitude and move close enough for the ground to pop in, you either have to fly at ridiculously high angles of attack that take you down within a few hundred meters within seconds to see your target, or you'd have to use a full function cockpit to do radar target selection.

No worries, the average heights for a jet in Arma would easily blow a window. It's a great way to demoralise a target. In the Iraq war, the SASR used an American jet to fly over some kind of production factory/plant (forgot what for) and yeah, it blew out all the windows and the Iraqi's came out with the white flag. They didn't even fire a shot.
