Thanks again everyone! Ohhhh I didnt know that the Fokker70/100 had a stabilator *doh* - as one of you said that *does* explain the large housing sitting on top of the tail. I guess I was getting in a flap because I though only the elevators should move!At first I thought it was normal but then I looked at photos of F-100s and saw nowhere near the extreme deflection as the PF 100 so I new something was up!n4gix - Thanx :) I shall do the same and punch in those numbers!

Does anyone know what it's for though?

<<< Does anyone know what it's for though? >>>I think you are asking about the housing on top of the Fokker 100 tail?My guess it that it houses a similar mechanism to that found on the MD-83, mainly a jackscrew that tilts the stabilator up & down. But Im not well-versed on these things so its just a guess :)Heres the internal structure of the MD-83 T-tail though:http://www.cnn.com/interactive/us/0002/ala...grx.screw.3.jpg

Hi there -I think I meant to ask what was the whole thing for.I mean that other planes don't have such big movements in their elevators and I would think that if it went out of whack when you were flying you'd be in, lets say, a bit of a pickle.A lot of a pickle.

Ahh ok! Go to the link belowScroll down the page a little and theres a nice explanation of a stabilator vs. normal elevator - including a simple interactive flash animation.http://www.professionalpilot.ca/aerodynami...trols/pitch.htmHope it helps :)

>At first I thought it was normal but then I looked at photos>of F-100s and saw nowhere near the extreme deflection as the>PF 100 so I new something was up!As you've no doubt found (from the link you provided), this is actually a trimable version...The one thing that is truly odd though is that the "housing" shouldn't be moving at all, I should think. The typical installation has the axis of rotation at the aerodynamic center, pivoting on a fixed axle.However, since I don't spend a great deal of time watching the a/c's tail, that's really a trivial issue for me... :)I'm just delighted and pleased as punch to even HAVE this cool little bird back in the virtual sky!

Very interesting site and explains just why the Fokker(and many others,I guess) use the stabilator. It's more efficient. This is another great post!

<<< However, since I don't spend a great deal of time watching the a/c's tail, that's really a trivial issue for me... >>>Yea, sometimes its nice to look at the jet from an external view & gloat at how good it looks (specially if you have a capable computer)And I got this screenshot forum I go to for FS2004 and I wanna post pretty pics of my Fokker 100...but sometimes it looks like the tailplane is being broken off cuz of the wierd stabilator angle!....and to rub it in further everyone elses Fokker 100 stabilators look just fine in their screenshots!http://instagiber.net/smiliesdotcom/kao/otn/pcrying.gif

change the aircraft.cfg line - (in all the PF aircraft)from:"elevator_trim_limit=24.324"to read:"elevator_trim_limit=12.5"All the best,Dave.'Three greens and soft landings'

>>change the aircraft.cfg line - (in all the PF aircraft)>from:>"elevator_trim_limit=24.324">to read:>"elevator_trim_limit=12.5"Hmmm... on December 17, 2004 I wrote the following:============================== In response to Reply # 2Fri Dec-17-04 11:36 AMby n4gixThat is the result of having the pitch FULLY UP... The aircraft.cfg shows the upper elevator_trim_limit=24.324 degrees, which seems rather excessive for any aircraft...I've changed all three aircraft.cfg files to elevator_trim_limit=15.00 and that seems much better to me...===============================Thank you for making the same suggestion... ;)

The F100 shares the same stabilizer configuration as the BAC-111 (or was it the Trident?) in which part of the tail moves with the stabilizer.It is NOT a stabilator but rather a trimmable stabilizer. The elevators SHOULD work as normal just like the 737 or DC-9 or any other airliner.I have no idea as to why it is acting that way.
