P47 Thunderbolt familiarization
This video from the US War Department explains how to fly the real P47 Thunderbolts from startup to shutdown. You can also learn from P47 FSX specific A2A videos (P47 Razorback addon).

Technical information on the p47.
Limitations and procedures come from A2A user guide, and from P-47 Thunderbolt Pilot’s Flight Operating Manual.

Check lists (standard procedures)
Preliminaries
Check controls for location. Check that gear handle is DOWN. Check flaps handle is in UP position. Flap equalizer, on models having it, must be DOWN (closed). Generator switch ON. Intercooler shutters NEUTRAL. Oil cooler shutters NEUTRAL. Propeller switch ON and selector in AUTOMATIC. Fuel boost pump to START and ALTITUDE (full counterclockwise). Check fuel pressure. Gun switch OFF. Adjust rudder pedals.
Starting Procedure
Turn propeller several revolutions by hand with ignition OFF. P-47B: Ignition switch to BATT. P-47C, D, and G: Master battery switch ON. Supercharger lever OFF (full rear). Fuel selector valve MAIN. Crack throttle 1/4" to 1/2" OPEN. Mixture control IDLE CUT-OFF. Propeller switch AUTOMATIC. Circuit Breaker ON. Propeller control maximum, 2700 RPM. Fuel boost pump control to START and ALTITUDE. Prime 2 to 4 strokes if warm, 4 to 6 if cold.
As much as 1/4 throttle opening and heavy priming may be necessary when extremely cold.
Ignition switch to BOTH. Energize and engage starter, push mixture forward to AUTO RICH as soon as engine catches.
If engine stops due to being loaded, open throttle wide, and return mixture to IDLE CUT-OFF until engine starts again, then retard throttle and return mixture to AUTO RICH. Throttle to 900 RPM.
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.
Check magnetos. With flap selector handle UP, equalize flaps. Unlock tail wheel and taxi.
Takeoff
Set trim tabs: elevator NEUTRAL, aileron NEUTRAL, rudder TAKEOFF. Mixture AUTO RICH. Fuel selector valve on MAIN TANK. Flaps UP. Cowl flaps OPEN TRAIL. LOCK tail wheel. Open throttle; do not to exceed 42" (with 91 octane fuel). Watch for overheating, AVOID at all costs!
Power Settings
Takeoff ManPress: 52" (if 91 octane do not exceed 42") RPM: 2700 Climb ManPress: 35" RPM: 2500. Cruise ManPress: 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 the runway.
Checklists (emergency procedures)
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.
