I found this Checklist in the MSFS Forums. It's was made by David A. Seest and can by found here.

I simple change a few things to get the Checklist more in line with the aircraft we actually use in the sim, therefore I changed/added the following things.

  • Converted Temperature from Fahrenheit to Celsius
  • Converted Airspeed from Miles per Hour to Knots
  • Added "(INOP)" to parts which are at the moment (and to my knowledge) inoperable
  • Changed the Checklist Title from "Checklist - Beechcraft G18S" to "Checklist - Beechcraft D18"
  • Changed the climb RPM and Manifold Pressure from ' 2150 RPM / 32" ' to ' 2000 RPM / 30" ' (According to "I'll take the 18" and this video ,giving me in the sim, at a climbrate of 1000 fpm, around 120 Knots, which is, according to the original author the upper border of airspeed while climbing)
  • Change the cruise RPM from "2000 RPM" to "1850 RPM"

I want to make clear I am NOT the author of this Checklist. All the credit goes to the original author David A. Seest
