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.

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.

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!!!!!

The tailskid is fitted to.........737s, 734s 738s 739s 753s 763s 764s 773s Concorde. Any more i've forgotten. I can't remember if any MD-80s have it. Maybe the MD-82/83/90 have it fitted -- i can't remember

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

OK, WHY does that ATA plane say British Airways and Air Malta???
Johan!! Fake picture alert!!!!!
life wasn't worth the balance, or the crumpled paper it was written on

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.
