Hello people!

 

Today I made some flights with a B736 aircraft with honeywell MCP and analog standby-instruments installed.

I was not able to made an autoland. Is this normal with this configuration? I don't get the "LAND3" indication on the PFD as in other aircraft configurations (for example Collins MCP).

Instead of "LAND3", it stays on "CMD" an no futher. RWY alignment during autopilot approach was also horrible.

Please see the section of the FCOM on the fail-operational vs. fail passive autoland company option. "LAND3" is an annunciation of the fail-operational version, which does not exist in the Honeywell MCP (sim or in real life). The Collins unit combined with the ISFD contains an extra AP channel that gives it the fail-operational triple redundancy. What you saw is correct for the Honeywell MCP - it does not have a rudder channel or rollout guidance and it is not guaranteed to be able to continue the approach in the event of a channel failure like the fail-operational version is.

Check out Ralph's fantastic video too

this video of mine is shot without fail op option, ISFD or HGS. The MCP is the newer one, but the operation is same.
