supersonic

[xaedus 10]

Can any of the jets go supersonic? If so can ground troops hear a sonic boom as the fighters pass by?

In real life the Su-34 and F-35 are the only aircraft capable of supersonic flight.

The F35B is coded as "maxspeed=1400" which if I take that to be km/h translates to 756 knots which is definately above Mach 1 by a small margin. I do doubt that supersonic effects are modeled but that's just my gut feeling.

There are no afterburners in the game and (as far as I know) none of the aircraft in the game have supercruise capability, so it's very unlikely you'll see an aircraft go supersonic in the first place, let alone hear a sonic boom.

Modders will surely add this later.

The jets should be able to go Supersonic, I never tried as yet but it was almost possible to go supersonic in OFP with the A10 from a high altitude dive. Theres no supersonic cracks/bangs from jets in ArmA2 from what I know (I'm sure someone would of posted it on youtube by now if there was), though BIS could probably easily do it similar to how supersonic bullets crack in ArmA/ArmA2 (just need to use different sounds and how far the sound travels)

Frederf most modern aircraft fighter IRL are supersonic. ;)

Think that you will need a much bigger map/island for a proper use of supersonic or supercruise flight. Lets see how such stuff and effects can be implemented in a proper/realistic way.

I think Frederf was refering to the aircrafts present in ArmA2

Using afterburners, yes. Not many fighters can achieve supersonic speeds without them (supercruising capability). Since afterburners aren't modelled in Arma2 (yet) and neither the F-35B nor the other aircraft in the game have supercruise capability, none of the aircraft should be able to go supersonic anyway.

Go supersonic and you'll miss the island.

Hehe then Frederf was too fast or he didnt get his cup of coffee :D

Anyway with setVelocity you can give a boost to F35B, AV8B and the Su-34 - or any other thing. Now there isnt a sonic boom but new flyby sounds. Imho BIS should first of all improve AI flight skills/behaviour. Its too easy to pick them off.

Yea, u can go supersonic :)

Test flying can be hard on a guy! :D

Of course I specified which aircraft in ArmA2 are capable of mach one. Of course with setVelocity anything is possible.

By the way, Espectro, 1247 km/h at sea level is slower than mach one.

Mach 1 is 761mph and he was traveling at 774 mph so he was doing faster than mach 1 unless there is something about being at sea level that I dont know about?

Mach 1 is "the speed of sound" which depends entirely on the air medium. The higher the altitude, the slower Mach 1 is in TAS. At sea level standard conditions I think your 761 mph figure is right or at least close enough.

I converted 1247 kmph to 673 knots which I thought was only slightly higher in mph. No one in aviation uses mph so it's a really unfortunate measure to talk about anything regarding airplanes. Yeah that should be M1+ so I was wrong. There wasn't any audio effects where there?

The same applies to tank shells that transition between supersonic and subsonic during their flight. You should get a crack during that transition but you don't. Bullets that have a supersonic muzzle velocity will always snap overhead even if they drop to subsonic during their flight.

Whoever said "Oh they don't have afterburner so they must not be capable" made a huge assumption that BIS models things that accurately. There's no military power or afterburner according to BIS just "speed." The F35B in the config has a maxspeed of 1400 (kmph) which is indeed supersonic.

Not all aircraft with afterburners are capable of supersonic flight at all altitudes, either (in real life).

[Amuro 10]

He probably wouldn't know even if there were as the pilot can't hear it. Also, I think you get sonic boom only during transition from subsonic to supsonic, not the other way.

I guess it's just not implemented :D

[Alex72 1]

Nope, but with the new soundengine and directional sounds etc who knows what we can do. In ArmA1 we have flyby sounds like in ACE so its easy to make a "BANG" when a jet flies high in the sky passing us for example.

Bottom line again: This is ARMA! Nothing is impossible. :)

[eble 3]

The aircraft addons I converted for Arma1 had sonic booms, even if they weren't perfect.

I'm expecting greater things in Arma2 better sound for people on the ground :)

1400 km/h is well over mach 1.3 at 30000 feet and standard temperature. In real life, F-35 can reach mach 1.6 with weapon load.
