Engine Warm-up
and
Pre-Takeoff Check oil pressure; if 25 lbs is not reached in 30 seconds, SHUT DOWN engine.
Do not increase power above 1000 RPM if oil pressure is 150-200 lbs. Wait until it is normal, under 90 lbs.

Climb MP: 35" RPM: 2500.
Cruise MP: 27" RPM: 2350 (after 10 hours; first 10 hours: 25" and 2250 RPM.)
Landing Do not lower landing gear above 200 MPH.
Do not lower flaps above 195 MPH.
For partial flaps, return flap handle to NEUTRAL.
Never exceed 250 MPH with landing gear down.
Do not use up all of the runway, land as near as possible to the beginning of therunway.
Emergency Flaps
Procedure In case of failure of the engine-driven hydraulic pump, flaps may be manually lowered by use of the emergency hand pump located on the left of the pilot's seat.
Emergency Gear
Procedure In case of failure of engine-driven hydraulic pump, to retract landing gear, move control handle to UP position as usual, then operate the hand pump until the panel warning light indicates the gear is up and locked.
To extend landing gear, move control lever to the DOWN position as usual to releases the gear, which should drop into position and lock due to its own weight. If gear is still not locked down, yaw the plane from side-to-side.
WARNING -- Always complete the landing-gear cycle, if possible. If handle is moved to UP, allow gear to go completely up before moving handle again. If handle is moved to DOWN, allow gear to go completely down before moving handle again.
Gee... our AH P-47 can have full flaps down around 200 and one notch at 400 MPH... hmmmm, I wonder where that data came from.
