What is that protruding from the fusalage toward the back of the a/c. It almost looks like the rear stairs except that they're to small. Any theories?

It's a hook to allow that plane to land on aircraft carriers. Looks like he is on a short final for the USS Carl Vinson.

Yeah, it looks like the stairs, but I've had a good look at it and I really don't know either..  Confused

I'm sure that somewhere, someone is on Photoshop putting together that exact scenario.

Here's another shot....

I don't know what it is technically called, but it's there to prevent overroation on takeoff. If you pitch the aircraft oo high on rotation that little thingy prevents you from scraping your rear fuselage on the runway.

Hope this helps

Could it be one of those tail bumpers, like the Concorde has?  Confused

It's kinda like that, yes. Though it's not really a bumper, it's just there to keep you from over-rotating on takeoff.

yeah thats exacty what it is.
So the aircraft wont over rotate.. its just a prevention as to the saftey of the aircraft. I dont know why these 727`s have them I dont think others do?
and I think that the airlines might of just used thouse aircraft for the time being since that company was going to sell its 727`s
I think dudes..

The tailskid explanation makes sense. The fact that I've only seen these on ATA 727's begs the question: did ATA 727 pilots have a particularly tough time with over rotaion on these planes? I'm kidding here - I have heard (from a TWA driver) that over rotation was a problem with the type.

Its called, appropriately enough the tailskid, and it is, as
aloha stated to protect the rear fuselage during an overrotation on takeoff or landing.

Electrically powered on the -100 series, hydraulically on the-200 it operates in conjunction with the landing gear.
If an overrotation does occur it will be noticed during a walkaround inspection by the presence of scrape marks, or in a more severe impact there is a crushable 'cartridge' attached that will be, well, crushed.

That would require a more thorough inspection by maintenance.The tailskid itself does not PREVENT an overrotation, the physics of a 160,000lb aircraft acting
against a 'puny' tailskid are obvious.

However all modern jet aircraft have to prove in certification called VMU tests that they can be rotated
to such a high pitch attitude on take-off that the tail actually scrapes along the ground until the aircraft lifts
off. You may have seen pictures of this, where the test
aircraft has sparks and flames visible from the tail
the manufacturer will usually mount a wooden skid to minimize any damage.

Aircraft therefore are geometrically limited from reaching
a pitch attitude where they cannot liftoff, or accelerate
as happened on several early Comet accidents where the aircraft was overrotated to such an attitude and indeed, crashed due to its inability to climb or accelerate.



The best contribution to safety is a competent Pilot.

I know for sure that the 753 has it too. And I'm not 100% positive on this but I think that also the 763 and 764 use it, and of course the Concorde.

The famous tailskid! It's on all the 727s I've worked on as well as many other types. The 767-200s don't have it but the -300 and -400 do! You should see some of the things pilots try to cover up.........but the scratches on the tailskid don't lie....BUSTED!!!!!

Aloha 737-200 it is a genuine picture as both British Airways and Air Malta did actually use American Trans Air B727-100s to cover fleet shortages during the early 1990s.

Having flown on the Boeing 727-200 as a flight attendant the protrusion is indeed a protection device against tailscrapes.

what the hell. its getting really old to not like people because of their age. if you didnt notice... i was proving how the aircraft IS real... and that it would be hard to fake that pic. but i mentioned that YES if SOMEONE wanted to they could take an ATA 727 and put BA lettering on it. I never said you did. and if im such a stupid little kid then why the hell do you care? dont you have better things than to b*tch at people online who are most likely half way around the world from you... and whats even funnier is i was saying the pic was real, but IF it was fake (which someone else mentioned ALOHA 737-200) then the person did a good job. ... haha

I logged N284AT at MAN on 3rd May 1988 and put a little note stating it was operating for British Airways (British Caledonian), which makes me believe that one of the routes it was doing was LGW-MAN.

For "Aloha", who went hyper: N287AT the picture in the title tread was actually leased by AirMalta for the summer of 1987. I know, I flew on it. Although I cannot confirm the BA titles, I assume it was a similar lease. I remember seeing the BA 727 soon after our lease expired and always had the impression that it was N287AT wearing the BA titles. Now it seemes that it was a different plane.
About the tail protrusion, that is called the Cooper Vane. It is only extended in slow flight. In high speed it is automatically retracted by ram air (I stand corrected here). This is to prevent the airstair from being opened in flight. It took its name from the famous hijacking of a B727 over the Amazon jungle where the infamous DB Cooper hijacked the plane, ordered the pilot to descend to FL100, depressurise and then opened the airstair and jumped with millions of dollars he had just stolen.

Well and it was my mistake. I did not know that Air Malta and British Airways borrowed ATA 727s for a time, I apologize.

I was basically going on what Rapo posted with the second picture, no offense was intended.
