Full Stall Landing

Pilots talk about doing a "full stall landing" and they are completely full of shit.

Just because you hear the stall warning horn in the flare, doesn't mean that
your wing has exceed Clmax. It comes in at 5-7 mph ABOVE the stall, so your
AOA is still less than Clmax. You are NOT STALLED. Get it?

If you ever make the dreadful mistake of getting the airspeed down low enough
and the nose high enough at a low enough height to actually fully stall an
aircraft before touchdown, the resulting high rate of descent is sure to pound
the shit out of you and the aircraft. This is a loggable "hard landing" which
legally requires a maintenance inspection and may or may not have damaged
the aircraft.

So. Anyone that tells you they fly "full stall landings" is a liar. Or they are
destroying every aircraft they land. You know. An idiot.

My life has been a surreal contrast. Because I work as an engineer with some
super-bright people, and I hang around with pilots, who think they are super-bright
people.

But I note that many pilots don't know sh1t about aviation. Yet they lecture on
subjects that they know even less about.

Free advice, worth what you paid me for it and sure to hurt your feelings:

When you think you are seeing things clearly, ask yourself if you're enjoying
the view from Mount Stupid:

Have some self-doubt. People without self-doubt scare the shit out of me.

Always be examining the axioms of your logic, and your logic that leads you
to your conclusions.

Don't believe anyone else's bullshit. They're all used car salesmen with conflicts
of interest. Don't believe my bullshit or anyone else's. I don't want followers. I
want leaders.

Do your own critical thinking, and reach your own conclusions. Never, ever
out-source your strategy even though you must sometimes contract out the
tactical implementations to the tradesmen (lawyers, doctors, mechanics, electricians).

Don't doubt those that fear, fear those that don't doubt. ;)

I wish the anti-vaxers would exercise some self doubt about their beliefs and actually look at all the available data, not just what their favourite web site tells them.

There is more than enough information out there to make an informed decision, but I have yet to hear from a anti-vaxer that is open to any information that challenges their world views

I have done one full stall landing in my flying career. It was in a Navajo that had about 3 inches of ice all over it as I found out to my considerable consternation, that the boots didn’t work. I drove it down final at 120 knots flaps up and then flared to a level attitude just above the runway and slowly reduced power. At about 100 knots it suddenly stopped flying and dropped the last foot to the runway like a brick. I am pretty sure that wing was totally stalled.

Hey Colonel.

When you get to fly a DC3 you will find it is a pussy cat to wheel land.

But you should do a three point with it, that is a bit more difficult and can be real interesting.

Let us know how it goes. :mrgreen:

Exactly.
When you get to fly a DC3
Sigh. I wish I could get the time off. I booked Friday last week off to change cam timing
belts, and it didn't look like it was going to happen, but it did. One day off is all I wanted.

I know there's something wrong with me, but I would give your left nut, Chuck, to fly this:



One hour in that is worth 10,000 hours in anything made after 2000. Note for the premature
ejaculators: skip to the landing at 5:30

Speaking of which.. just mucking with a 360 cam but here is a full stall tail wheel slightly first example.

Hi Peter. Nice video. I personally love the technique of tailwheel first landing,
as is recommended in the Pitts POH. When that occurs, the mains come down
immediately, the AOA is reduced, lift is reduced and flying is done - no hopping
and skipping down the runway.

Small nit - you did not exceed CLmax during that video, so I don't think we can
honestly call it a "full stall" landing - just a "textbook perfect" landing :^)

I do the same thing here - tailwheel-first touchdown.



But again, at no point in that video do I exceed CLmax. You can hear Eric's stall
warning horn honk, but again, that merely means he is close to the stall - not
actually stalled.

Very nice… thats hard stuff side by side. Yes not quite full stall. The Extra is even worse, you can drag the tail wheel on the runway with the mains 3 ft off the ground.. makes a hell of a thunk.
