LNAV and VNav
Autopilot remains engaged. Autothrottle disengages. FMA's will be _______ LNAV with an amber bar across it, and VNAV also with an amber bar across with a careted >autopilot EICAS message meaning the autopilot is in a degraded mode. Autopilot goes into HDG hold and VS but the FMA's do not change. But it's been 2 years since I've last flown the B744
