A recent discussion over the past 6 mos was closed on March 25 as the issue was reported as fixed:
Most of my flying has been in GA aircraft over the past 3 years in VR. I’ve only been flying the 387-10 for a few weeks. In some flight plans generated from the world map the heading select mode won’t disengage and go back to Lnav. On other routes Lnav is fine. Am I missing something? I’d appreciate any feedback to help solve the issue. Thanks.
