Jim Hall Posted March 14, 2023 Share Posted March 14, 2023 Sorry to be a bother but my Cessna 172 idle rpm is 680. What should it be and how to get it?

Jim Hall Posted March 15, 2023 Author Share Posted March 15, 2023 Okay, thanks. Just seems odd that when idling my plane keeps taxiing. i7-7700k @ 4.2 Ghz, 16 GB DDR4/3000,2280 SSD M.2,Genome II Case,Nvidia GTX 1080 rear exhaust, Samsung 40" HDTV & Two 24" HP side monitors.

tiger1962 Posted March 15, 2023 Share Posted March 15, 2023 That can happen if you have a tailwind and/or a downward slope on the apron, taxiway or runway.

Jim Hall Posted March 16, 2023 Author Share Posted March 16, 2023 Mine won't roll to a stop after landing. You gotta use the brakes which is fine, I guess. I forgot if that is so in the real Cessna 172. On the one occasion I flew the real plane, while taxiing back to the ramp, I was wiggling back and forth and my CFI asked me what's up. Oops, I had got used to steering with my toe brakes on the sim. Also in the sim I look mostly at the instruments and not the horizon. I guess when transitioning from sim to the real plane you have to unlearn some bad habits. 1 i7-7700k @ 4.2 Ghz, 16 GB DDR4/3000,2280 SSD M.2,Genome II Case,Nvidia GTX 1080 rear exhaust, Samsung 40" HDTV & Two 24" HP side monitors.

Just for comparison, the FSX default 172 idles at 600 rpm and it take 1100-1200 to start rolling. These are pretty close to an actual 172 that idles between 600 and 800 rpm and taxi rpm of 800-1000.

PhrogPhlyer Posted March 16, 2023 Share Posted March 16, 2023 I've attached a quick reference checklist for the Cessna 172 that may be useful. Happy simming.

jlaurie Posted March 18, 2023 Share Posted March 18, 2023 Quick fix to stop rolling at idle is to apply the park brake. ASUS Intel core i7-8700 NVIDIA GeForce GTX1070 8Gb DDR4 16G HDD 1TB SSD 256GB (M 2) MSFS2020 Advanced system Link to comment Share on other sites More sharing options...
