AFMS Section 2.8 Autopilot Coupling Limitations
This section of the AFMS contains two possible limitations:
[a] No limitations for autopilot coupling.
[b] Lateral GPS coupling (LNAV only). For 430W/530W units: The GS of an ILS (VLOC) may be
coupled to the autopilot without any limitations.
For all autopilots covered by the 400W/500W Series AML STC, limitation [a] applies and should be
checked on the AFMS.
