777 fuel press on off "press" means off in PPF
In Prelimanary preflight inspection .All the overhead lights button display off and on or blank meaning off expect for the fuel panel,if you check for on it says that check pressure light illuminated on all light except for centre pumps which has pressure lights extinguished,So for fuel panel is the off meaning of primary fuel pumps,like eng and centre main tanks PRESSURE acutally meaning thats its OFF actually.Since ive previously flown airbus im a bit unsure.thanks as it has dark cockpit philosophy,also
