Hmm, I've operated S/F with door open couple of times, but do not remember any INHIBIT to tackle. The above proc: yes, to re-introduce HYD power. Quite sure here that RUMBEAR did not mean to call the 0 HYD press an INHIBIT. Can we get an FCOM reference pls?
@hans: Different parts of the world, whole countries refuel with 1+F for the longer part of the year. Natural selection perhaps?
