I've been looking into various POHs available online regarding the fuel pump. In the manuals for pre G1000 versions with the PT6A-114A engine, the shutdown procedure matches what's in our manual (I'll use "our" to refer to the manual for this addon ):
Parking Brake SET.
Avionics Switches OFF.
Standby Power Switch (if installed) OFF.
Fuel Boost Switch OFF.
Bleed Air Heat, Ventilation Fans and Air Conditioner (if installed) OFF.
Inverter Switch (if installed) OFF.
Power Lever IDLE.
ITT STABILIZED at minimum temperature for one minute.
Propeller Control Lever FEATHER.
Fuel Condition Lever CUTOFF
My confusion arises because, starting with the G1000 version, even though it has the same engine, the shutdown process changes. I'm not sure if this is due to safety recommendations or some adjustments made for the G1000 installation:
POWER Lever IDLE
ITT STABILIZED (at minimum temperature for one minute)
PROP RPM Lever FEATHER
FUEL CONDITION Lever CUTOFF
LIGHTS OFF
FUEL BOOST Switch OFF
AVIONICS No 1 and No 2 Switches OFF
So, for "our" Caravan, it makes sense to stick with what our manual says. I'll keep researching to find out the reason for this change.
Regarding my question about the Ignition switch being in the ON position, all the different POHs I've seen specify that:
The IGNITION Switch should be turned ON to provide continuous ignition under the following conditions:
1. Emergency engine starts without starter assist (refer to Section 3,AIRSTART).
2. Operation on wet or contaminated runways.
3. Flight in heavy precipitation.
4. Flight in moderate or greater turbulence.
5. During inadvertent icing encounters prior to the INERTIAL SEPARATOR being selected to BYPASS.
6. When near fuel exhaustion as indicated by Red RSVR FUEL LOW CAS MSG.
So, don’t forget to include this note in your checklists and flows to enhance realism and immersion!
I still have uncertainty about the fan vents. My doubt comes from a fantastic video I recently watched about how to do a correct walkaround. I might be misremembering, so I'll review it.
Once again, I want to express my gratitude for the time you take to answer my questions and requests. I can imagine you have plenty of work preparing for the release and all your upcoming planes, so I feel a bit awkward bombarding you with these details. I'm passionate about understanding the Caravan, and I know my enthusiasm can sometimes be a bit much
