A very quick video on how to start the engines on the DC6. The video starts after the AFE has finished the Before Start Checklist

 

I'm curious about where did this procedure come from. It really works, but it's not what we have on POH as you can see on page 201.

2.2. starting engines

1. Start engines in following order — 3-4-2-1.
2. Engine selector switch — position to engine being started.
3. Safety switch — “ON” frst; then start switches “ON.”
4. Turn engine over with starter. Watch propeller motion. If any sign of hesitation or stoppage occurs, disengage starter and investigate. After engine has turned freely 11 to 14 blades, turn ignition switch “ON.”
5. Fuel booster pump for engine being started—“LOW.”
6. Primer switch — “ON” as required.
7. Mixture control — “AUTO RICH” after engine fires.
8. Trottle — adjust to 800 to 1000 engine rpm, watching for engine and cabin supercharger oil pressure rise. If pressure does not show within 30 seconds after starting, stop engine and investigate.
9. Fuel booster pump — “OFF.”
10. Hydraulic system pressure — check (2600 to 3050 psi).
11. If external power source was used to start engines, turn battery selector switch to “PLANE BATTERY” and disconnect external power supply after all engines are started.

More convenience and saving time moving up and down all the time in the cockpit. In the real aircraft you have 3 persons in the cockpit, in the sim you are alone.
