PMDG und LNAV

[HJOrtmann]

die Meldung sagt eigendlich alles (dein aktueller Kurs führte nicht zum aktiven Waypoint), aber einmal googeln bringts nochmal ausführlich:

Lateral Navigation (LNAV)
Pushing the LNAV button arms or engages the AFDS in LNAV mode. This mode permits
the FMC to control the roll channel and so follow the active route. If the aircraft is more
than 2.5nm from the active route, LNAV appears white (armed) on each ADI. Previously
engaged roll modes remain active. If the aircraft is not on a heading which will intercept
the active leg of the FMC route, the FMC light illuminates, and the FMC MSG lights
illuminate and "NOT ON INTERCEPT HEADING" appears in the scratch pad of both CDUs.

If the aircraft is at or within 2.5nm or turning radius from the active route, LNAV appears
green (engaged) on each ADI. The AFDS then follows the active route.

LNAV mode is disengaged by selecting HDG HOLD or HDG SEL mode, or when localiser
caputure occurs.
