Hi, I have some problem about autoland.I have set nav1,2 to ILS frequency ,both course and CMD A,B but when LOC and GS capture it still show SINGLE CH in PFD . I think I do it same tutorial and I do it many times but it didn't. First I think it was a bug.What should I do? Thanks.

Which Autopilot are your using? If you're using the Collins, do you have Fail-Operational selected? If not, then what you see is correct. I suspect you're expecting to see LAND 3 or LAND 2. You only get that with Fail-Operational selected and that feature is only available with the Collins system although optional.

With fail-passive you will have CMD mode when FLARE arms, but not yellow SINGLE CH.

True but re-reading the original post, he says he still has SINGLE CH at LOC and GS capture to which I'll add, you either get CMD (Fail-Passive) or LAND3 or LAND2 (Fail-Operational) passing ~1500AGL and fully established.

OK,I just find the reason,I selected fail pass in setup and then I changed ti fail op and it work,Land3 is active so, If I use fail pass it won't show LAND3 but it will show CMD right?(LAND3 have Roll out and Flare arm but CMD have only Flare arm)

If I use fail pass it won't show LAND3 but it will show CMD right?

 

Yes.

 

(LAND3 have Roll out and Flare arm but CMD have only Flare arm)

 

Yes.

In FCTM5.26-5.29 you can find all the differences.

Thankyou everyone.
