Let me see 18 Wheeler?

CT7 Turboprop.

Check voltage Batteries(24)/GPU(29.5)
Batteries on
Check Bus-tie
MainBuses off
Emergency lights off
Autocoarsen off
Bleed valves auto
Power Levers Ground idle
Condition Levers Fuel off
External lights set
Ignitions off
Starter engage
ITT below 175 degrees/NG 17%
Condition Lever start
Ignition auto
Watch ITT rise, anything above 965 degrees and it's all over (cost of an average house in surburban Sydney!)
Ensure smooth continuous NG rise otherwise prepare for abort
Watch for starter cut-out at 55% NG
Note ITT peak
Associated generator reset then on. Ensure bus-tie.

The above does not include the procedure for hot/hung starts, or the career ramifications if you get it wrong

Check Generator/GPU voltage for second start.
Repeat for second engine

After engines start.
GPU disconnect
Generators on voltage check
Emergency lights armed
Recirc fans on
Ignitions guarded
Autocoursen on
Main buses on

Go to after start checklist

Condition levers to max. Check correct bottom governor operation.
Activate Ice protecion systems through the AC Generator

Probaby not as simple as it seems!
