767-300 Single engine autoland?

[stilton]

I’ve flown the 752/3, 762 and 764

None of these subtypes were certified at my operator for a single engine autoland


Anyone out there who has flown for an operator who was / is approved for that procedure?

As far as I know the only two Boeing types approved for that are the 777 and 787

[rudestuff]

Yeah. 75 and 76 can both do it.

[deltahotel]

Some of our 75s and all of our 76s.

Fail Operational 737 NG can do it too to CAT 3A minima

[oceancrosser]

Same thing here as Deltahotel says, about half the 752/753 fleet and all the 767s. It might be a generational thing with the 757s, the older ones can’t but the later builds can.

[Commander Taco]

All 767s at my carrier were certified as well for s/e autolands.

Interesting


We were not authorized at my carrier, one of the first actions on the engine failure checklist was to turn off the autothrottles


Understand the Autopilot can autoland on one engine but will the AT remain engaged ?


What about rudder control ?

[deltahotel]

Man thrust, idle at 25RA. Rudder by AP once Land 2 or Land 3 annunciations. F25, F20 for GA. Absolute minima 50RA

On the 767 (and 757) the autothrottle won't function or engage with an engine out. So manual thrust would be necessary.

[Matey]

On the 737 the autothrottle is reengaged once FLARE ARMED is annunciated and rudder control is active, Ie upon engagement of the second autopilot at around 1500ft. It remains engaged until reversion to manual rudder control in the event of a go around and change of mode

Check Airman, you need to remember the 757/767 autothrottle basic design is over 40 years old - in was in fact the first digital autothrottle Boeing did (the 747 A/T - Full Flight Regime Auto Throttle (aka "FFRATs") was analog - now that was 'uncivilized').
I suppose they could have added 'engine out' capability when they did the new engine upgrade to the 767 in the late 1980's (the 747-400 A/T has engine out capability) but it would have affected commonality with not only the older 767s but with the common type rating 757 - and that was considered a big no-no (we were looking at implementing autostart on the 767 around 1990 - but the study was shutdown because of the potential impact on the 757 common type rating).

Ha! Just yanking your chain tdracer. I love my Airbus, but deep down, I’m a Boeing fan

Thanks for the very informative replies

I can't recall whether the single engine autoland feature is a question of operator specifications, a particular option package purchased, or actual aircraft serial number. I know some 767's are approved for single engine autolanding, and I know from experience that the simulator does a really nice job (with manual throttle for all the aforementioned reasons). As for yaw control, once the ALIGN mode is engaged, the autopilots do a great job right up until 400 feet AGL on the go-around...at which point you'd better have a foot on the correct pedal, or you're going for Mr. Toad's Wild Ride...
