Beech Premier 1A, Lift Dump on Demand
Just curious ... sounds basically like a switch to manually trigger ground lift dumper deployment instead of using squat switches?
What else is in the system? Any safeguards to prevent accidental deployment in flight? Any feature that would auto retract them in the event of a rejected landing, or is that manually done?

loud warning if you power up with lift dump deployed. Lift dump must be armed with a switch, it's on the landing checklist I believe. I don't believe there is protection from deploying in flight. The system is designed to NOT rely on accurate squat switch function.

Can deploy in flight. 3 boards per side. System is locked except for takeoff, (for an abort), and unlocked prior to landing. System is separate from speedbrakes, and power will not cause a retract. On back of pedistal, it is a t handle that is illuminated white when armed. A unlock switch,an emergency manual lock release, and Warning placard about not deploying in flight are beside it. Alarm sounds if handle moves without deployment. Early Premiers had to have weight on wheels, but this was later changed after a rash of runway overruns after failed deployment. There was an SB issued to convert the older systems.
