To be fair a similar system on the Dash 8 Q400 has a pretty nasty habit of folding up on landing.


sort by: page size:

Commercial airliners have autoland systems. Much less common in smaller planes.

Any airplane with a nose wheel lands that way.

I mean… it’s an airplane. It’s not like you can just pull over onto the shoulder in case of catastrophic mechanical failure.

Why is this? Can they do a better (in terms of passenger comfort) job landing manually?

The belly flop is also how passenger variants will be landing so you do actually need a reliable program....

Planes are designed to land without or with partial landing gear. That's the redundancy.

Lying flat would be a really bad time on landing, particularly with thrust reversers!

For landing I wonder if you could fold the wheels in first and just fall back into driving stance.

The plane usually lands down.

Nosewheel should never be anywhere near to being the first thing to hit the runway. In a Piper, for example, this would be an easy mistake to make but if you're landing a Gulfstream with the nose that low-down, you're in serious trouble.

Yes. But sometimes, the plane randomly decides it should tenderly hug the ground.

See Boeing 737 Max and it’s infamous autopilot


There have been several cases of the landing gear up/down lever getting wired backwards during maintenance. Not to worry, the gear has a 'squat switch' sensor that prevents the gear from being raised when the plane is on the ground. Unless you taxi over a bump and the switch decides it's now airborne. Crunch.

I'll have to try that, my back plane always takes off at the worst time.

That's not an automated landing system failure, that's a landing gear failure.

This is absolutely the case. Both in cases where the gear is semi-functional, and when it is not functional at all. For reference, here is what a belly landing looks like on a 767:

And using the ground proximity to guide a landing instead of altitude has lead to some crashes I have read.

> One interesting thing about the Beluga: the pilots very often fail to land them and have to do multiple attempts!

They're likely just doing a fly by for a visual inspection of the runway since it's not a major public airport with full time air traffic control.

Most people are smart enough not to park something in the middle of a runway but might not have an intuitive grasp of how large a wingspan these things have.


The Airbus A320 can't either. It's not required as long as the landing system is designed to handle the fully-loaded weight.
