November 27, 200421 yr Is there any place where I can find a chart that shows power settings for the Cessna 172 (or the other aircraft in FS2004) whereby I can determine what power setting (RPM) to use for a specific operating speed, climbs, descents, etc? Thank you.
November 30, 200421 yr Use 1000 RPM for taxi.Use full power for climb.Refer to performance chart in POH for power settings at various altitudes.Use 2100 rpm to descend from enroute phase to approach phase. Reduce power as necessary to reduce airspeed to at or below turbulence penetration speed and maintain desired rate of descent when air is not smooth.VFR: In the pattern use 1900 rpm for 90 KIASIFR: Use 1900 rpm for 90 KIAS for the initial/intermediate segment.VFR pattern: (base leg)Use 1750 rpm for 500 fpm descent @ 80 KIAS. Adjust as necessary to maintain airspeed and descent rate.Reduce power to maintain 500 fpm descent and slow to 70 KIAS on final, reduce power to cross threshold at 65 KIAS on short final.In the real world IFR approaches are flown at 90 KIAS throughout the initial/intermediate and final approach phases for the C-172. Speed is reduced when the airport environment is in sight and the decision to land has been made. Circling approaches are done at 90 KIAS.For IFR final approach segment:For precision approaches use ~1800 rpm to maintain 90 KIAS and glideslope.For non-precision approaches use ~1600 rpm to maintain 90 KIAS and 750 fpm descent.Engine settings here are approximate because in the real world these setting vary somewhat with each individual aircraft: how it is rigged, errors in instrumentation, loading, cg position, etc.In the flight simulator the flight models vary somewhat between different software packages, so the numbers I report here may differ from those you actually end up using, or what other may tell you. The numbers here I report should be used as an approximate setting, used as a guide so that you can refine these setting for your own use as you fly these phases.
