F300
Above this, start may be possible, but not assured.
In flight start?
Move fuel control switch to run.
If X-Bleed shows, need to move start switch to Start, and with Autostart available, move Fuel control switch to run immediately.
Moving reverse thrust to reverse idle does 2 things.
1) disconnects Autothrottle
2) Engages auto speed brake, even if it was not armed.

L C1 C2 demand auto
(Counter Clockwise circle from
R demand)
Shutdown:
Clockwise from C2 demand (ending where you began with Demand R)
If Center hydraulics have an entire leak, does anything remain operative?
Standpipe should allow pressure for C1 Elec pump to work, giving:
- Alt/Res brakes
- nose gear and steering
If have a hydraulic pressure issue, what to do?
Follow checklist.
But basically, Demand should act as auto back up.
Turn demand pump to On, in case auto didn’t work.
If that doesn’t work, turn primary and demand off.
