A stronger stabilator
down spring in the E model improves longitudinal stability, but control pressure in the flare suffers as a result.
This occurs because the stabilator
sits up out of the propwash, and so is less effective at low airspeeds.
To briefly restate what the article should have said concerning the AGPU and aircraft: Electrical power from the AGPU can move systems like the stabilator
and other electrically-driven systems.
The F-105 "Slab Lock Mod" was a switch-activated emergency system that would lock the stabilator
in neutral position to prevent the plane from pitching down when both flight control hydraulic systems were lost.
At 50 knots, airspeed dissipated due to increased nose attitude, decreased power and increased parasitic drag caused by stabilator
programming to the near-full-down position.
The new method helps to ensure the availability of the flight-critical stabilator
amplifier used on Black Hawk helicopters, one of the workhorse aircraft of Operation Iraqi Freedom.
systems can be mounted on rails or rubber tyres.

The airplane landed hard, separating the nose and right main landing gear, and damaging the aft fuselage and right side of the stabilator
The same stabilator
that had so much authority when the airspeed was too high tends to run out of ability when the plane gets too slow--especially at forward CGs.
