Yesterday, despite rather bad weather with high winds and cloud cover...errr "industrial haze :D"... I got to jump from a Russian made AN-28. Takes 20 skydivers to 14 000 in about 10 minutes, total turnaround time 20 minutes. Has a tailgate:

Bit of a bad spot left us spread out over several kilometres, but managed to land between two hangars (and scaring myself because of all the turbulence, no fun)
Anyway, the plane has a twin tail thing. Obviously it's a great jump plane, because the tail is placed high up and away. But now I'm curious; from an engineers point of view, what are the benefits of this design? It's not something that's very common for some reason.
Any of you smart aeronautical dudes have any answers? Will need them soon; have to have some wisdom to brag about in the bar tonight
:D .

There you go.

Yep fixed it, my bad. Too much to drink yesterday.
-
I was confused for a second, because it was broken when I looked at it, then worked by the time I had posted, making my post useless.

She's 26, blonde, former elite soccer player (with the fitness that comes with that), a medical doctor. Blonde. Has the same nose as me (i.e a tad too big, but that's charming). Way smarter than me, and she's been supporting my skydiving habit for a year now (will soon earn money working, so that'll at least stop).
I have some pics somewhere, but won't post them til a prospective buyer has provided me with an initial 100 jumps. Good faith thing, you know.
She can be yours for 200...scratch that, 400 jump tickets. :D
There are quite a few skychicas out there. True, it's a male dominated sport, but we have a saying:

Very cool. :cool:
:aok

Im so impressed by that. Gonna have to think about jumping myself.
:D
-
I think you should post pics o fher asap.
Always wanted to skydive but never found the time or balls to do it :D

With santa's Heavy magnetic arse alone his sink rate would be triple of the standard parachutist :D

:aok Sounds hot enough for me... I need pics for proof though..
Umm, I don't jump out of perfectly good airplanes, take me up in that russian one, then I'll jump. :D

To piggyback on what Gscholz said, sometimes they do it because it means they can have two shorter vertical tails instead of one large one and get the same effect. Definitely a consideration for Navy planes (F-14, F-18) where space is a factor. The F-15 has twin tails too, because a single tail would have been huge, thus making it a big target to shoot at. Probably not a big concern for your jump plane, but those are a couple reasons why designers go for the twin tail design.
-
I would thingk: more tail area .
also, for multi engined planes, the tails will be in the slipstream and thus can be canted to minimize the p factor.
-
You couldnt get me to jump out of a plane for all the money and women in the world.
:D

Ah ok.
I was wondering whether it has something to do with centre of gravity issues?
In the Skyvan and similar planes, only ten skydivers are allowed at the ramp at any one time - the reason being that if there are any more, even full forward deflection by the pilot cannot keep the plane level - it'll start a climb and then stall.
And what's the p factor?
Geesh, this is scary - I'm getting an interesting in non combat planes...
Hawklore, lol, Russian iron rules. Was soo sweet to just get on, feel the acceleration, the very short takeoff length, the 8 minute to alt and then a *beautiful* open tailgate. Just stepping out into freefall is a surreal feeling. Had a big sh|t eating grin on my face the whole time. The cessna takes 25 minutes to alt, so I was about to do my "snooze a little" routine when sis pointed to altimeter and a broken English voice said "two minhiits til droph".
And I absolutely LOVE the red light -> yellow light -> green light GOGOGO thing. Makes me feel like some kinda SEAL :D
