Hello Anders,

You asked: A few questions.
Do all three A/P�s lit (engage) when you "catch" the GS and Localizer?
In my case only the left one (L) lits as it does during the flight.

Do I have to dial the CRS (343 in this case) in the HDG of the MCP?

It's been a while since I actually flew the 767, but if I remember correctly you must have the APP switch armed prior to arming additional autopilots required for autoland. The APP switch, when armed, also arms the previously engaged single autopilot for capture of the localizer and glide slope.

The left FCC is powered by the left AC & DC busses; the right FCC is powered by the right AC & DC busses; and the center FCC is normally powered by the center AC & DC busses. However, when the third autopilot is armed, the center AC bus transfers to the static inverter, and the center DC bus transfers to the hot battery bus. This feature provides three separate power sources for the three autopilots.

At 1,500 feet radio altitude, with LOC & G/S captured, the other autopilots engage hydraulically. and the ASA's indicate autoland capability. FLARE & ROLLOUT armed appear in the ADI's. Rudder authority is available to the autopilots for yaw control if an engine failure were to occur.

If you selected the proper ILS in the computer then the course will appear. The heading cursor will slew to the inbound course at LOC capture.
