B737 single-engine landing minima?
Hi guys,
Having a total brain infarct here (not flown the Boeing for a few years now).
Can someone clarify what the landing minima is when you're single-engine in the Boeing.
I seem to recall it was CAT 1, but I've been told it was CAT3a with a a/p disconnect at 50 ft followed by manual landing, any truth to this?
I looked in the manuals, but all the Vol 1. says in limitations is MUH (minimum use height) for single channel a/p approach is 135 Ft.
Our part B states you must disconnect A/p at 135 ft.
Could someone tell me what the answer is and where I can find it?

Would be interesting to know if in those 737s that are equipped with a HUGS (head up guidance system) a one engine out CAT II/IIIa approach is still possible since you can fly it manually anyway.
In normal planes it is not though.

As far as I'm aware, only the newest 737NG's (end of 2004-present) have the ability for single engine autolands. Anything before that (definitely all classics without HUGS) will be the standard one-engine, one a/p approaches with MUH 135ft.
The brand new NG's have a totally revamped a/p (think it's a RC as opposed to Sperry?) which is DUAL-DUAL. My Company has several of them but we don't actually use the CATIIIB ability due to training costs / software fit, I believe.

Well, you could certify the classics to be CAT IIIa able without the need of an autoland if you had a HUGS installed. So the autoland was not a necessity for CAT II/III.
And yup, our new NGs have CAT IIIb capability as well.
