Boeing 777 engine-out cruise question
Hey guys
Just a quick question. Looking at the engine inoperative cruise technic in my manual, I've noticed a big difference when VNAV is engaged, and when it's not.
With " VNAV not engaged " :
- Select CLB/CON on MCP
- Select a lower altitude on the MCP
- Select FLCH and disconnect the A/T
Why would you disconnect the A/T right away in FLCH and not in VNAV ?
Sorry if the question seems stupid, or maybe I just miss a key point here, but I can't figure why..
Thanks !
