PFM...
Some of the spoiler panels moved to a null position (7 degrees) when the flaphandle was moved past the 30 degree position.
Forward pressure on the pole resulted in spoiler extension (to a max of 14 degrees), whereas aft pressure on said pole resulted in spoilers retracting.
Worked OK, for the very finest in automatic approach/landings.
Required a definate technique for manual flying.
As some found out, the Boeing 'push' did not work.
