Aces high is a dogfight sim, not really a flight sim. I'm not interested in knowing how to warm the magnetos in a p51.
I just used my checklist. Just like ever other pilot in the world does today.
DCS Startup Checklist I used from flightace37 on the Eagle forums...
----
=== Pre-Start ===
Flight Controls: CHECK Parking Brake: SET Stick Lock: NEUTRAL uselage Fuel Gauge (Shoulder): CHECK Left Fuel Gauge (Floor): CHECK Right Fuel gauge (Floor): CHECK Flaps: UP
Carburetor Ram Air Control: FORWARD unless filter required Carburetor Hot Air Control: FORWARD unless hot air required
Rudder Trim: 6* RIGHT/As Desired Elevator Trim: 2* NOSE HEAVY (4* with tanks) Aileron Trim: 0*/As Desired
Landing Gear Handle: DOWN **Do not raise gear on ground**
Mixture: IDLE CUT-OFF Propeller Control: FORWARD Throttle: 1 Inch OPEN Gunsight Gyro Power: ON Gunsight Mode: As Desired Gunsight Brightness: As Desired Weapon Selector Switch: SAFE Bomb Arm Switches: OFF Gun/Camera Switch: OFF
Altimeter: SET Directional Gyro: UNCAGE Flight Indicator: UNCAGE Supercharger: AUTOMATIC Fuel Booster: ON Ignition: BOTH Fuel Shutoff Valve: ON Fuel Tank Selector: LEFT WING Battery: ON Generator: ON Position Lights: ON/CHECK Cockpit Lights: CHECK/As Desired Signal Lights: As Desired Landing Gear Lamp: TEST Supercharger Lamp: TEST Oxygen Gauge: 400 PSI Radiator Cooler: TEST/AUTOMATIC Oil Cooler: TEST/AUTOMATIC
== Start-Up ==
Prime Engine: 3-4s if cold, 1s if hot
Starter Switch: START (Hold)
Mixture: RUN (When engine catches)
Oil Pressure: 50 PSI within 30 seconds, Warm-Up Idle: 1200-1300 RPM to 40*C oil temp, steady pressure, Suction Gauge: CHECK 3.75"-4.25", Engine Instruments: CHECK, Idle: ~1000 RPM
If engine cuts out, set mixture to IDLE CUT-OFF. Re-prime 1s for restart. Starter is good for 4 attempts before 5 minute cool-down.

That takes around 1 minute when you've done it enough. And when I get tired of the realism setting, I switch to easy mode and press E to start my engines. Like I'm sure 90% of us DCS pilots do.

I mean, if you want uber stupid crasy realism, sure, turn up the realism on. Knock yourself out. But time is precious, and I would rather spend my minutes flying and in the air that trying to figure out why my engine isn't starting... I hit the start 4 or 5 times and end up wasting time before trying again because I left my fuel booster off. :
