Hi Guys,
Just going through some paperwork and came across a questions that had me stumped.
During takeoff the normal outflow valves begin to meter when the:
A. PSEU is in the flight mode.
B. Powerlevers are set 15 degrees above flight idle.
C. Bleed switches are turned on.
D. Power levers are set to climb.
I know this is a very ambiguous question but no where can I find reference in the ODM or flight manual to the actual way they come on. With power levers on take off in AUTO mode and past 15 degrees, the pressurisation system commands the aircraft's pressurisation system to pump up to 140 feet below. But there is another reference to having one or more bleed switches on before this will occur. In MAN mode this will not occur. So either answer B or C in theory would be correct but in the spirit of multiple choice, which would be "more correct"
Cheers,
SO :ok:
