ADDED I did more digging this morning and it looks like what he have to do in accordance with our maintenance Tech Orders (1A-10C-2-71JG-2), which I listed below originally, is different than what is in the pilots checklist (1A-10C-1CL-1). Per the latest dash 1:
MOTOR is used for air-purging of excessive fuel, cooling the engine, or manual starting. When the switch is moved to MOTOR, the following actions are accomplished, provided electrical power and an air source are available:
- Air Turbine Starter (ATS) valve opens, causing the ENG START CYCLE light to come on
- ECS shutoff valve closes
- Both engine bleed air shutoff valves open.
The engine operate switches are powered by the DC essential bus.

FYI, Motor switches work in the current DCS A-10C but not completely accurate, they work mirroring the procedures we have to follow in the maintenance TO procedures:
Comments in the video about Fuel Boost Pumps and Engine Generator switches. I can’t recall if I reported those years ago (along with a handful of other topics he mentions). Setting those switches is not actually part of our launch Work Cards but a I always set these switches (plus pulling up certain knobs on the intercom panel) prior to the pilot stepping.
During Pre-Flight Basic post Flight or Combined Basic Post Flight/Pre-Flight inspections it’s actually a carded item to make sure all switches are “off, safe, or normal” except main air and bleed air switches. If they’re not in Supply or Bleed and someone forgets to pin the external battery pin it will drain the battery.
Couple of the items mentioned in the video were reported back when I was a tester and mentioned again when I created the below thread. I hope between Habu validating them, and this being a direct result of a USAF contract they get addressed for A-10C 2, current A-10C, and where applicable A-10A.
