Hi Spanner
With Doors open, Engines OFF, APU ON Spoilers 1,2,3&4 Deploy on the ground. Just trying to figure out when will the following statement be true.
"Note1: For maintenance purposes, the speedbrake lever will extend the N°1 surfaces when the aircraft is stopped on ground, regardless of the slat/flap configuration."
My understanding is, only spoiler on each wing should deploy.
