737 NG PFD channel display for autoland...?

Recommended Posts

When you engage the second AP for an autoland and have tuned the Nav 2 radio to the destination ILS as well as Nav 1, is the display on the PFD still supposed to read "Single CH" down to the 1500 AGL confidence self-check, or should it read "Dual CH"?Thanks!Jonathan Sacks

I think it still reads 'Single CH'

And then at 1500 AGL when the 2nd AP engages....?It still reads Single CH. Seems there is no way of knowing that DUAL CH is active on the way down other than looking at your nav radios. But perhaps that is normal (?)Jonathan

It flashes yellow and changes to CMD when both a/ps engage at 1500ft
