LNAV track interception and trackign

[anthonygalushka]

Version

v0.5.1

Describe the bug

Tracking NAT track and the A/C is oscillating between the track deviating left and right of the aircraft. Track does not remain centred, instead flys with this oscilation with a period of ~10s. This was present on a regular waypoint to waypoint tracking as well. Track interception exerpeinced this as well.

Expected behaviour

Track the NAT with little deviation. Not this much oscillation, considering winds are stable with no turbulence.

Steps to reproduce

Bank Limiter Auto, nothing special from what I understand on the systems side. LNAV active with a regular cruise speed of M.83.

Additional information

Attached is the streamable clip of it above.

I also noticed this behaviour.
LNAV lost its track (somehow, might have been PEBKAC) and when i noticed it was on HDG mode, and moved to intercept the track, it was unable to do so properly due to steering into the track too sharply and then banking too slowly to actually get on track.

I got a little sick but it seems that it does it more at cruise than at lower speeds. I assume the calculation for the intercept isn't taking into account the higher speeds.
