Ohh!! So you did a pre-flight checklist. I think the question is if we can pilot the airplane. Not just start it. Lol.
Yes, but each company varies slightly. And actually... I've heard of crew members being discharged because they didn't do what their company wanted them to. Boeing might recommend using both ignitors on the engine, but Alaska Airlines on the other hand, prefers that you only use one of the ignitors, alternating every start. Why? Because it preserves the ignitors on each engine. I have access.. And there is kind of a need, unless you feel like going unemployed. I doubt anyone will want to hire a person who deviated from their company's SOP in the past, that spells "untrustworthy" in many shapes and forms.
Okay. but just saying, if you were to try, have fun sitting on the ramp filling out paperwork.
