I've been asked quite often about the engine start procedure for the A2A+Accusim B-17 Flying Fortress, so I'm going to post it here, from memory. Correct me if I'm wrong, but I believe it goes like this:
Battery 1, 2, and 3 - on (3 switches, up)
Inverter - on (bar connecting two switches, up)
Ignition - on (large metal bar, up)
Magnetos (all engines) - on (all 4 small levers rotated full forward)
Fuel (all engines) - on (raise red/white bar, 4 switches forward, lower red/white bar)
Fuel boost pumps (all engines) - on (4 switches, up)
Carburetor Filters - on (switch with 4 lights above it)
Throttle (all engines) - cracked 1 - 1.5"
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Fire Extinguisher Select - Engine 1
Primer Select - Engine 1
Prime Engine - 3 to 12 times based on temperature (warmer=less, colder=more)
Engine 1 Starter - on
Wait 12 Seconds, expect co-pilot to shout "Clear Prop!" early
Engine 1 Mesh - on
Engine 1 Starts, Starter and Mesh switches return to neutral state.
Oil pressure and RPM up
Engine 1 Fuel Boost Pump switch - off
Engine 1 Inverter - on
- - - - - Repeat for Engines 2 through 4 - - - - -
After all engines are running, Hydraulic Pump to "Manual" until Hydraulic Pressure reaches 800+, then "Auto"
I do recommend that you give control of your engines' Cowl Flaps, RPM, and Turbo Cooler to your co-pilot to lighten your workload. (Shift+3 panel, I believe)
