boeing dream,
in level flight, A/T provides speed protection & speed control. reversion mode is not available because, if required, that would mean a departure in level change from the mcp selected altitude or vnav altitude restriction, something mr.boeing doesn' t want to happen. e.g. how many times( in initial training & later) did we try to select V/S to no avail because we forgot to FIRST select a new altitude on the mcp?
many thanks & always welcome,
kind regards,
bm
