To point 7 about the boost pump.
Totally realize how my explanation would be a bit tough to understand.
So the way the system works is that there is a 10PSI switch on the fuel line and the switch should activate at 10PSI +/-2 PSI. When that switch comes on, it will throw the annunciator message for the FUEL PRESS, and if the switch turns back off, then your FUEL PRESS annunciator will turn off. This is purely a switch in the engine compartment, not talking about a physical switch in the cockpit
When the aux boost switch is in auto, that 10PSI fuel pressure switch will also activate the aux boost pump to come on, but when the fuel pressure switch turns off, meaning the boost pump has done its job, the boost pump will not turn off like the annunciator light does. Instead the boost pump will remain on until its cycled. Now, this doesn't mean the switch has to be turned to the off position, though that will also reset the auto function, it only has to be brought back to the ON position for a second or so, then when you switch that back up to the AUTO position, the boost pump will not be on, the pressure will drop back down onto what the engine mechanical pump is providing. This is assuming its in flight and the mechanical is working. As far as the shutdown goes, which is where most people will see it, if the engine isn't spinning, the mechanical isn't pumping, the fuel pressure will always be too low so whether the switch is in auto or on, the boost pump will be on until you switch it off.
Your understanding is correct, it latches until "reset" by turning the switch to on or off then back to auto.
Its very much appreciated that you took the time to read this and are willing to address these.
Like I said, I'll take the time to run it through a full maintenance list like I would in the real thing to point out any other things, but as far as a normal flight goes, the original post were the things that stood out to me. The only other thing I'd mention off the top of my head is if the prop blade tip supersonic snapping audio could be reduced/eliminated above like 40-60 knots indicated. I think from what I read its an audio pack from someone else, but that snapping sound goes away once there is good airflow over the prop heading down the runway. Or have some headset on type ANR to dampen it. Its a bit much to listen to for a full flight.
Example here maybe if I know how to upload a video to youtube and share it right? Mind you this is a 700, but its the same 4 blade hartzell prop spinning at the same speed.
