Cessna 172 Checklist - Infinite Flight

Hello folks!

It’s me. I’ve been thoroughly enjoying the recently updated Cessna 172, especially with all the new features it brings. It is detailed, and IFLLC did such a great job bringing us an amazing aircraft.

I wanted to make this checklist for people who may have been having some trouble starting up this wonderful bird. If you have any questions or comments, please let me know. Thanks!

Hi there! Can you please elaborate more on the mixture settings (eg percentages) A lot of people (like me) don’t understand. Love this by the way.


Absolutely. It ends up varying depending on many factors, although I can try my best. I don’t entirely know the percentages for high-altitude takeoffs and landings, if anyone is good at those.


Make sure you close your windows. I forgot originally.

Going to bookmark this. Maybe copy and paste everything into a doc and print it. Thanks so much, I really needed this!
They also have these online as well and they are somewhat compatible

This is brilliant. Maybe at the beginning from personal experience we check flaps and lights are all working before doing much else. So full lights and flaps to verify and then continue on with the normal checklist …

It should be rich. Not best power. Always rich for takeoff. Then lean as in cruise

Set 1/4 inch

Should be set before start incase of engine fire or other necessary.

Pre start, prior taxi- check magnetos left and right, and check for dead cut

Nearly there matey. Just a few minor things. I’m a 172 student pilot so if any of y’all like a real life answer of video of the checklist, happily PM me :)

Also I have a 172 checklist if y’all need any touching up on any of the checklist parts. @me Also. Happy to help :)


Unless you are in a high elevation airport. Full rich in high elevation will flood the engine

You can’t do that in IF. It is equal to approx 800-1000 RPM, which is about 10%.

Read the checklist. The engine hasn’t been started yet.


@Will_A MaxSez; Try thus one… I posted it yesterday:

Do you idle once you pass the threshold?

Thanks for representing us 172 pilots

Isn’t this a general checklist though. I’ll look in my irl checklist in a minute

Mixture should be rich. As specified in the Checklist

I also have a G1000 checklist I can post when I get home


Oh nice. Would love to see. As much as we have IF sim pilots on here, it helps to have pilots who fly the 172 irl who can provide true, real life procedures and information

Indeed. Simflying can only get you so far you need first hand experience


I turn on my avionics before I start the engine just my preface
