PA46 Piper Malibu Before Starting Engine Checklist

The first in my series of posts about the checklists in hopes of filling in all the gaps that Carenado left off. First of all I don't really see what is the point of putting a checklist with items that are either inoperable or just not applicable to the simulation. I also noticed that some hotspot switches have a function different from what the panel label (in the VC) actually says.

So, for the list, those items with [X] I got covered, those with [?] I am unsure where to find them and those with [  ] are those that I believe do not apply to the simulated aircraft. Please correct me if I am mistaken please! I want to make a true checklist for this wonderful plane!

[  ] Pre Flight Check according AFM (what is AFM?)

[?] Door Pins (somebody said they should be green inside the door but I do not see them)

[  ] Seat Belts

[X] Parking Brake

[X] Gear Lever

[?] Emergency Gear Knob

[  ] Circuit Breakers

[X] ELT

[X] All Electrical Switches (I guess only those on the overhead)

[?] Radio Master Switch (tooltip says "Master Avionics")

[X] Alternate Static Source (I think underneath the main panel, Alt. Switch)

[  ] Cabin Altitude Selector (inoperable)

[X] Cabin Altitude Rate Control (dummy switch)

[?] Cabin Pressurization Control

[X] Cabin Dump Switch (overhead switches)

[?] Oxygen Pressure Gage

[  ] Oxygen masks

[?] Ground Clearance Switch

[X] ATIS (tune radio - IVAO/VATSIM)

[X] Startup Clearance (IVAO/VATSIM)
