Denied jumpseat by SkyWest with open seats!
#41
The JSer is a CG problem, common to need 500-800 lbs ballast in the rear bin to balance out the CG. When you're full boat that ballast has to come out of either pax or fuel. I'm not taking off with less than MINTO (or anywhere near MINTO in most cases), and I'm not lying about fuel on an airplane that transmits actual fuel load to SGU as soon as you go wheels up.

Look at a picture of a 200. The CG is near the aft wing root. The JS is a quite a ways farther from the CG than the cargo bin. Why is the CG that far back? Because this isn't a 73 or a bus... the motors are on the tail.

I've found it interesting that if you move the jumpseater from row one to the actual which is maybe 72" you go from being in C.G. to needing 400-800#'s of ballast in the cargo area. The jumpseater is only 190#, the distance from the cargo area to the C.G is about the same 72"?
Must be the arm from the C.G to the actual jumpseat position is longer than to the cargo pit?
On the 700 & 900 you sometimes need to move people forward!

You probably want to delete this. Then again you have proven that you have no idea what you are talking about.
I’m glad you don’t work at skyw, and I hope you’re an anomaly at Compass.

As far as the ballast issue, I am not sure but I have heard several theories, one being that our galley is different and causes the plane to be nose heavy. Also, that some 200 operators have a heavy metal plate installed at the rear of the plane, which we don't have. And something about hydraulic 3. But its just stuff that I have heard on the line and I don't have any proof or data to back that up.
I remember being in CVG and telling the ramper we needed to add ballast and he got super upset saying that we are consistently the only company that asks for ballast.

I've also heard that AWAC has a permanent ballast kit in their 200's and doesn't impact their operation as badly because most of their operation at lower altitude cities. I've been to some of our stations and they would report that they are out of sand ballast and that may effect how many pax we could take. I bend over backwards to get a JS on and I have never seen one of our Caps to intentionally deny.
If a JS was denied, the reasons may have been valid CG issues. Keep in mind the station gets a load report before the flight and it could list to the station unable cockpit JS.

I have burned off fuel to get a jumpseater on in the past.

I understand there's an option for a PERMANENTLY installed ballast that solves a lot of CG problems. But that is an option for the COMPANY, it is not an option for the PILOTS... they fly what the planes as provided by the company. I'm sure ALPA would have the ballast installed in no time. Actually SKW probably didn't install the ballast because they fly in the west and need flexibility to deal with density altitude in the Rockies in August.

Look at the airplane (including the engines). The JS moment arm is about four times longer than the bin's arm. Also IIRC the cargo door is at the back of the bin, so the CG of the actual cargo is even closer to the wing than the cargo door.

Was always fun having a V1 of Mach 10 at flaps 8 bouncing down 25 in DEN. Sooo we gonna rotate today or what?
