Autolanding is so boring so I shouldn't respond to this but as it is stadet in the manual you must have both nav-radios set on the ILS-frequency and make sure that they are in manual mode. After that you can engage both channels on the autopilot and hope for the best.
Why don't you land manually instead it's more fun and not very difficult ?

0 RVR :) Although one can still land in 0 vis, its sorta against the rules hehe

Hi there, this is copied from one of my earlier posts and updated for AUTOLAND.
This is standard CAT 3 ILS procedure, I will not refer to flaps, gear speeds etc. as these are on the chart that has been already posted.
ALL LANDINGS BELOW 1800 RVR WILL BE AUTOLAND (in real life)
Set ILS freq for CORRECT runway 'Under the BAR', this means in the right hand window of NAV1 and NAV2
Set ILS front course in the course selector on the MCP.
Set NAV1 and NAV2 to MAN (as opposed to AUTO)
Fly at a 30 degree intercept (NO STEEPER!) towards the localiser usually in hdg sel. mode, with one AP engaged. Ideally aiming to intercept at 10-12nm out. (or as ATC req.)
Select LOC on the MCP, then arm second autopilot
YOU MUST BE BELOW THE GLIDE SLOPE WHEN YOU INTERCEPT THE LOCALISER!!
DO NOT TOUCH THE YOKE! Allow the autopilot to intercept the localiser on its own. once established on the localiser press APP
this will arm the glideslope capture. Again, Do not touch the yoke! Allow the AP to capture the G/S
You can monitor all this on the FMA above the ADI.
At 1250 ft RA (Radio Altimeter) Flare is seen on the FMA in white
This means FLARE ARMED. This is the indication that the second autopilot is armed. If this does not appear GO AROUND.
The 737-400 is CAT 3 ONLY and requires the captain to make good visual contact with the runway at DH in order to legaly land.
The 737 autopilot has NO capability to track that runway centreline and the captaim MUST resume control on touchdown to guide the aircraft along the runway.
The Captain can abandon autoland and make a visual landing if he get sufficient visual contact with the runway before 1000ft RA. after that he MUST continue and AUTOLAND.
As in real life, Monitor the Autopilot AT ALL TIMES. If the autopilot looses or is going to loose the G/S or LOC then disengage and GO AROUND.
You must ensure that you are at the CORRECT speed and configuration for each phase of the approach. If you are too fast or slow you will have trouble and find it hard! and so will the automatics.
I have tried to make this fairly simple it is a tad more complex on the real thing. but if you follow this procedure correctly you will find the AUTOLAND ILS easy. If you want to know more email me and i will recommend some real life reading for you.

Sounds like you are flying for Finnair?
