After firing one wingtip IR missile, that wing drops

[609_Relentov]

After firing one wingtip IR missile, that wing drops instead of the wing that still has a wingtip missile.  Seems the "weight of one wingtip missile" induced roll is doing the opposite of what it should do.  I don't have a track as the mission ran a while, but it's easy to reproduce.  Load wingtip missiles, fire one, and observe the incorrect wing dropping/rolling.

Also, another minor (possible) bug: After landing including deploying the chute, I didn't release the chute as I rolled to a stop.  After taxiing I shut down the engine and went to external view and observed the chute still in the horizontal position behind the jet, even after the engine spooled down.  Not sure if this is a bug, but it just looks funny without any jet engine exhaust keeping it deployed and not crumpled on the ground.

It's actually the correct behaviour.  The remaining wingtip missile's aerodynamic surfaces are actually creating lift.  You'll find as you slow down, there is not enough airflow for those surfaces to create sufficient lift and the wing with the missile will actually start to drop due to the missile's weight.

Interesting, I hadn’t thought of the lift from the IR missiles fins (assuming this is what you’re referring to).  I’ll have to check it out later.  I don’t recall this happening on the F-16 with its wingtip missiles, but maybe since the 120’s are heavier it still drops on the side with the missile remaining.  More to try out…

It's bugged in current version. Fixed internally, so you'll see it fixed in next OB update.

You're saying it isn't intentional?  In the Jan 25th patch notes, there's the following item:

• Rolling moment induced by external payload lift now accounted for.

It is intentional but needed to be tuned.

Hi Vibora. There is indeed an issue with asymmetric loads on F1 module.

Easy to test by having empty jet + BARAX pod. It starts to roll quite heavily, despite the light weight of the pod.

I recently read an interview with a Harrier pilot  (very different aircraft!) but even with those tiny wings he would not notice assymetric loads when flying at speed. Only time it was really noticeably was during landings as the speed came down.

I just wanted to post about the same thing but you beat me to it. ;-D So, I just flew a mission with that said BARAX pod and I also think, roll in asymmetric loadouts still needs some tuning as it is just too harsh under certain condiotions. Especially with just one Magic or Sidewinder missile left on the wingtip pylons roll is a bit too exaggerated in my opinion. So yeah, I would also opt for some adjustment in this area. Overall though, this patch is quite a remarkable step forward for the F1 so here is a big thank you to the Aerges team.
