Republic P-47 Pilot's Check List
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 MP: 52" (if 91 octane do not exceed 42") RPM: 2700
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.

Why wouldn't they be allowed to use all of the runway? Seems to me it'd save some wear and tear on the brakes.
-
So when did the pilots fly? Before or after getting blown to pieces because of reading the 2 hour checklist?
-
Whew, certainly glad Aces High is biased in favor of easier and more fun gameplay.

:rolleyes:

What's long about it? It's about what I have to do when I fly my little Cessna 210.:confused:
-
I think someone got outturned by a P-47 spitbolt. ;)
-
you mean, the P47 handbook has a speed for flaps, and if that speed is exceeded in game, they dont autoretract?
-
we need more complex engine management in the ct, it would never work in ma.

Luckily, I can press "E".

It takes longer to read that than to actually do most of that stuff.

That's a bogus list. There's NO mention of a beer holder..

I thought they used cartridge starters?
-
early jets used cartridge starters up through Vietnam... never seen a cartidge starter for a piston powered plane.

Cartridge starting was common. All F4Us prior to the 1-D used D type starting cartridges. The FM-2 used a C type cartridge. Early F2A fighters used an inertia starter, but beginning with the F2A-2, this was changed to an Eclipse type II cartridge starting system.
All USAAF fighters used inertia starting systems.

it's written here clearly that the P47 is over modeled and gamey.
I've used up the entire runway many times and the plane did not auto brake. All other planes auto brake at 2/3 of the runway which causes an unrecoverable ground loop and uncontrollable BBS whining.
The P47 was not able to use up the entire runway in real life. This gives the P47 an unfair advantage. HTC please fix.

Yep just press the mighty "E"
that all.

I'm not sure but perhaps they might be trying to say "aim for the numbers and don't land long".

This list will come in handy when I decide to steal a P47, sell it for several million dollars, and retire a rich man.

The only way you'll ever become a millionair owning a warbird is first starting off with 2 million.

I don't know about early jets, but what aircraft are you talking abou tin Vietnam that used a cartridge starter system? Also, the aircraft that did use the cartridge system , did not use it as the primary starting system. I understand that it was used as a backup only. I also know of no "Jets" in Vietnam that used a cartridge starting system.

The A4M, Skyhawk had its own starter. One tap (pop throttle to the left) of the igniters and she'd light off.
No cartridges.
-
RB-57's used cartridge starters...
(http://kalaniosullivan.com/KunsanAB/OtherUnits/Pics/3rdBWFlightlineJohnsonAFB1957.jpg)
The MXU 4 A/A cartridge drives turbo/mechanical starters to start engines for aircraft such as the F-111, B-52, KC-135 and others
The F-100 and F-105's also used them...

It's not *that* bad.
Take a look at the complete startup and takeoff checklist for a Cessna 172 sometime -- it's not that much shorter!

Tempest and Tiffy used cartiges to start the napier sabre.

Much as I'd like to see the "USAAF Uber Flaps" toned down, I have to ask:
What if they're talking full flaps or takeoff flaps? 1 Notch is a small amount. Perhaps the 198MPH is meant to prevent destruction from a higher angle of deployment?
If you can find more info please send it to HTC! I'd like to see P41 and P47 and P38 flaps efficiency reduced.

I believe that refers to lowering full flaps, not partial flaps. At higher speeds the torque tubes would bend. Additionally, P-38 flap use in combat is extremely well documented, as is use in the P-51. However, using flaps in a P-40 to enhance turning was unlikely as the flap system was extremely difficult to use.
All of the above verified by actual pilots.

i assume you memorize the checklist, only glance at it in passing.
eventually it becomes a routine.
indeed it's a bit longer than one you would find for trainer, but not overly long.

I flew with some Navy pilots who thought they had memorized the checklists... Usually they would miss something. So, I would insist that they READ the checklists outloud, or they would not be flying that day. I would simply pull the cannon plugs on the VHF and UHF radios in the rack next to my seat... No comms, no flying. I kept a pair of dykes in my flightsuit just to cut safetywire, like that on the cannon plugs.
Whether or not you have memorized the checklists, it is flat out dumb not to read them. One mistake or oversight can get the entire crew killed.
I have seen pilots begin a takoff roll having failed to turn on the boost pumps, while not setting the flaps to 1/3 either. That is a deadly combination. Lose a mechanical pump and you lose the engine. Lose an engine on takeoff and and it gets dicey enough, but with the flaps up you have raised your single-engine minimum speed enough to get you dead. I don't think those guys had ever had their butts chewed by a 2nd Class Petty Officer before.
Checklists are there for a reason. Relying on memory is simply an accident looking for a good place to happen.

Widewing

I also know of no "Jets" in Vietnam that used a cartridge starting system.
The F-4C was very similar to the F-4B, even retaining arresting gear and folding wings, but featured a number of changes:
J79-GE-15 engines, which were similar to the J79-GE-8 engines used on the F-4B, but were slightly uprated and used a cartridge starter system, instead of an external compressed-air starting system. This allowed the F-4C to "self-start" and operate from remote airstrips with minimal ground support gear.

Wasn't the first plane with a preflight checklist the YB-17? The first prototype crashed on takeoff because of a locked elevator (or something that made it easier to taxi)? After that they initiated a checklist and used it on every B17 flight.
