Same seeing old TAP classic Tristars doing the same here at Faro

We had a pilot like this in our company. Every landing was performed like this. 737. He was the only one who knew how to land a 737, or so he claimed. Ex fighter pilot. That is how it was/is done on the F-16.
It worked until he aerobraked the tail into the runway.
It took him 20 years or so, but he got there in the end.

Well said. So it doesn't follow the FCTM guidance. Pick on the guy for that. Is there anything inherently dangerous though? The crew's landing on a long runway, and the plane's probably as light as it'll ever be. From the windsock, the wind was VRB01G02, so no issues directional control issues. It might even have been a retirement flight.

Safety was never compromised. He/she likely had fun. What's the big deal?

I now see this is on spectators balcony so maybe there is a different focus. But I was interested that nobody picked up on my earlier post that under certain circumstances the aircraft has a natural tendency to pitch up after landing. I had a quick look for examples and was reminded of a tail strike with a Chinese 777 in Amsterdam as well as numerous incidents with other Boeing twin jets. In this case all went well and for the spotters it looked good. But there are reasons this technique is not encouraged. Interestingly I also found a thread on Pprune about ten years ago describing this effect.

Spoilers deploy, weight on wheels obviously doing it's job (ground air switch if you want the correct term!)

All braking wheels working just fine, thrust reverse working just fine. Directional control still available from the rudder. No loss of braking action on the longest runway in the south east. Probably been cleared to take a very late exit as the traffic is low at Heathrow at the moment so had the full 3882m available. Fly the nose down, admittedly takes a fair bit of back stick at lower speeds. Continue. Some of these big jets are landing very, very light. Sometimes the 'normal' amount of back pressure holds the nose up a bit longer.

No one will be 'up in front of management' for what was a perfectly fine landing.

Depending on how the Company sets up their data monitoring system there would probably be a soft or a hard flag depending the length of time from main touchdown to nose touchdown. If they were inclined they could use that to calculate the distance the aircraft travelled, but to be honest you wouldn't be doing this if runway length was an issue.

Commercial aircraft record mountains of data, mostly it is automatically processed to flag events that meet certain criteria or used when investigating reported incidents.

You may well be right, though IMHO since even I could "grease" the nosewheel onto the runway on a 777 using the FCTM technique so I'm still of the " what's the point" opinion..

Trying to stick to Boeing advice kept me out of the office at BA and off youtube for over 30 years.

Absolutely right. Kept me out of trouble for many years! You are only as good as your last landing! I left trying stupid things in stupidly fast things behind many years ago.

I do seem to remember that N/W touchdown isn't a hard coded switch. It shows up as a spike on the landing data g-loading printout IIRC.

Way back in the mists of time Davis, in his book, "Handling the Big Jets" said that the only aircraft to benefit from aerodynamic breaking was a delta wing and I think gave the Vulcan as an example.

It is plainly obvious to anyone who has flown the 777 or similar that elevator authority is lost at the end of this guy's amazing wheely. You can see this from the rate of de-rotation. Some have seen (and felt) this from the cockpit and so can judge it even if you cannot. Not sure why you would say he never lost elevator authority when he obviously did. As for your other comment, I guess it's a good thing that attitude has been erased from the big airlines of the world.

By the way, re the touchdown, the 777 is ridiculously easy to land smoothly. You just wait for "30" then pull back a tad. Truck tilt does the rest.

As a TRI/TRE on the 777 with more than a few years experience on type (all Models except the -900) this is definitely how 'NOT ' to do it. If anyone was silly enough to do this during a check it would be an instant 'Fail'. When the aircraft runs out of elevator authority it will subject the NLG to a 'G' loading more than it is designed for, The FCTM may not be 'FAA Approved' however it is 'Boeing for Dummies' and you would need a very good reason not to follow its recommendations.

mmmmm, ok, your opinion.
I don't think he's lost elevator authority or that he planted the n/w. Not agreeing it should be done routinely!

Am more of the opinion that this was unintentional. I did the very same (only once) on a similar type (747-8) landing no autobrake, lightweight, idle reverse onto a very long runway when we had to vacate at the end. I was a new FO at the time and remember thinking the nose just stayed in the landing attitude until about 80kts then I rather luckily put the nose down smoothly, was certainly not intentional!

very unlikely.. The triple tends to want to lower the n/w so its a conscious effort to keep it up. Many pilots get caught out by this and allow the n/w to lower too quickly

......and that is why this forum has lost credibility.

Social media allows any enthusiast to make comment on technical issues that they’re not qualified to comment on. In some cases, not necessarily this one, that same comment can encourage, validate, or endorse others to emulate similar actions or behaviour. In all walks of life and regardless of your profession, people will be influenced by others.

In aviation, we train people to influence others in a good way. They’re called instructors and they’re a controlled influence.

Tom from Croydon isn’t an instructor or a subject matter expert. Perhaps he’s never flown before but he pulls a mean wheelie on his motorbike. Yet half the thread is full of unqualified gibberish from the likes of Tom (and sadly some ‘qualified’ people that should know better).

A cut and paste from the FCTM says it all.

If you’re not qualified to make comment good or bad, then don’t. By all means ask a question and if you’re qualified to answer it, do so.

If we can’t respect the first P in PPrune then the forum may as well be renamed Parka Pilots Rumour Network. That’s not a slight on the forum itself, but the contributors.

Pointless rant over...

The lack of/dilution of P pilots on this forum has rendered it almost pointless tbh. Pretty much every post is swamped with people that don’t have a clue what they’re talking about. Maybe there should be a sub forum for actually qualified proven professional pilots. I would certainly pay more attention to that...

I thought I'd flown them all but I've never heard of the "-900" !

You can see the elevator is at full deflection (or very close to it) up until the nose gear impacts the runway, then it's released. Hard to think this is unintentional.

Some people seem to think the wheelie is an indication of great skill and airmanship so maybe it should be part of the check to line. But it's no more difficult than holding any other attitude and I'd be alarmed if he couldn't do it! Nice touchdown, though.

Ahm , I`m no expert, but could it be, there was no green light for nose gear and because of this, the pilot lowered
nose as late as possible to touchdown with minimum speed ?

TRE

I am always wary of anyone who quotes their management or training qualifications as 20 years of RHS in legacy carriers meant that with two exceptions (one who went onto Concorde and an ex luftwaffe starfighter jockey) they were always hard work to fly with as they required extra monitoring and never lived up to their own egos.
Listening to their sermons my mind went blank.
