| However, by telling the FMC what you want it to do (before the flight), you can engage VNAV and LNAV (auto pilot modes) and in theory let it do it's own thing - In reality you rarely follow the FMC plan exactly so there will be some airborne adjustments to be made - OK, I am using the 733/5 as a benchmark here but assume the 75/6 doesnt require a whole lot of MCP (authopilot mode control panel) input either.
