Runaway Trim?

[328dude]

I'm just curious, but dosen't the "jungle weed" have some sort of elevator disconnect unit?. I can only speak for what I fly, but was wondering if your able to split the elevator by pushing or pulling in oppsite directions. I know you can on the dorkjet as well as the aileron's.

Is this also an option on the CRJ,ERJ,Avro,717, etc etc etc.....

I don't know about the Brasilia Jet, but on the Brasilia prop, we can mash the autopilot/trim disconnect switch. The 6 autopilot/trim servo breakers are also collared on the overhead for easy pulling. Don't know if this would have helped in the above mentioned situation, but figured I'd throw it out there.

The ERJ has an elevator disconnect, like every other transport-category aircraft, that can be activated either by pulling a handle or breaking the "clutch" between the two sides. That is only useful in case of a jam somewhere in the system, when the other side is unaffected. A stalled or runaway trim motor affects both sides, since the stabilator is moved too far up or down.
