[BUG] - LSAS Pitch Attitude Hold Activation Issue #1577

Open GR1MMly opened 1 month ago

GR1MMly commented 1 month ago

Describe the bug

It appears LSAS is active in a pitch attitude mode while hand-flying a gradual increasing-rate climb. When the simulated 2lb force is reached it snaps the elevator a degree or so.

Steps to reproduce

Handfly aircraft, begin gradual climb while slowly increasing back-pressure on yoke (Debug pitch up will allow monitoring of elevator incidence). At some point the elevator will snap 1+ degrees.

Expected behaviour

LSAS Pitch Attitude Hold or Automatic Pitch Trim should only be active if there is no force on the yoke. A gradually increasing backpressure should not incur LSAS, therefore there should be no LSAS manual override once a 2lb force is reached.

Auto Pitch Trim can also be identified as active following "Stabilizer Motion" trim warnings while hand-flying (and maintaining positive pressures on the yoke) and no manual trim inputs.
