fixed Aircraft requires roll trimming in crosswind.

[Deano87]

Hey all.

Been a while since I've been around (thanks Covid) but now that the F-16 is getting some more love I've been back here doing some flying.

I've found that the F-16 has a tendency to roll in the opposite direction to any crosswind it experiences. While its quite gradual and slow, this should absolutely not be happening as an aircraft flying in a constant wind does not experience any trim changes as seen here.

I tested this by making a mission (attached) with a maximum speed wind coming from the south, I spawned in an empty F16 at 35k ft pointing east. After the initial jolt of the spawn I let the aircraft stabilize and trim itself out, then I let go of the controls and noticed a slow bank to the left. After this I turned the aircraft left to due north and repeated the test, on releasing the stick I noted that the aircraft did not roll in any direction. After a few seconds of steady flight to the north requiring no corrections I continued the left turn to a heading of 270, where I noted a gentle roll to the right, opposite of what was seen earlier.

Conclusion: Aircraft banks due to influence of steady state wind - this should not happen.

Tested on a fresh install of DCS Open Beta 2.7.6.12852.

Mission and track attached.

Cheers, Hope this helps.

Can we get this reported? Makes the Viper a chore to fly in crosswind conditions without having to constantly trim or use AP.
