[BUG] Flaps 1 cause massive drag #3873

Closed pkoecker closed 3 years ago

pkoecker commented 3 years ago

Mod Version { "built": "2021-03-09T16:17:31+00:00", "ref": "master", "sha": "769da50970cbf3ef0f3e68dbd789553896084d1b", "actor": "Benjozork", "event_name": "manual" }

Describe the bug Flaps 1 cause massive drag. When settings the flaps to 1 even with full thrust it is very hard to climb or achieve any speed. When flaps are retracted the aircraft suddenly accelerates. Flaps 2, 3 and Full seem to work as expected.

To Reproduce

  1. Start with cold and dark cockpit
  2. Takeoff with flaps 1 or set flaps 1 in flight
  3. Observe massive drag

Expected behavior Flaps 1 should not cause massive drag

Actual behavior

References See https://youtu.be/ZvrGHqNNYP4 (Video is not listed publicly) Acceleration when flaps are retracted around 02:08 Deceleration with flaps 1 around 02:37

Additional context No further modifications installed that might affect this behavior AFAIK

Was this working before/when did the issue start occurring? The issue started with the new update to MSFS2020 today

Is this a problem in the vanilla unmodded game? I do not know

I concur the same after today's update. Immediately prior to update - was fine. Using FBW Custom. Thx.
