NickG Posted July 28 Report Share Posted July 28 Another great day with my Ovation (310 STC)! Flew from KHND to KAPV for a very expensive breakfast with a buddy - I started playing around a bit with the cruise settings to see the best combo of speed and efficiency. My preferred setting at 8-10k is around 21.7 MP/2500 RPM/15.7GPH yields a cruise speed around 175kTAS or so. Today I tried some different combos to see some more economical alternatives. I obviously have the POH engine charts (for both the Ovation and Ovation 3) - real world is relatively close. What do you my fellow MS’ers use? 1 Quote Link to comment Share on other sites More sharing options...
PMcClure Posted July 29 Report Share Posted July 29 For cruise, it is almost always full throttle and RPM 2500 and LOP 20 degrees. This usually gives me 175-180 knots depending on weight and the day and usually 14-15 gph. I can run it hotter/richer and get 182knots and 15-16gph. The Ovations really like LOP. I can give up a few knots at 50 degrees LOP and get down to around 12 gph. This may give me 168-172knots. Have fun getting to know your plane! 2 Quote Link to comment Share on other sites More sharing options...
EarthboundMisfit Posted July 30 Report Share Posted July 30 Would love to see some engine page pics/data for your IO550. WOT and LOP for us in cruise. Typically 175TAS at 12.5GPH. Our settings in the pics. Have also posted a reel/video of our leaning procedure on FaceBook - https://www.facebook.com/reel/1433105633994967 1 Quote Link to comment Share on other sites More sharing options...

Same here - usually fly WOT, 10-12K, 10-20 LOP, yielding around 176-180 kts, 13.5-14.5 gph dep on conditions. Flaming dragon mode is 16-17 gph = 180-185kts (usually reserve this for lower or stiff headwinds when I need the time). Mine loves LOP - with GAMIs I can even run it much leaner than this without issues. 2 Quote Link to comment Share on other sites More sharing options...

NickG Posted August 4 Author Report Share Posted August 4 I can't believe the versatility of these planes. Cruised around today at a leisurely 160 KTAS or so at 65% power burning 12 GPH. Can always go to my usual cruise of around 73-75% and go 174-178 KTAS on around 15 GPH . Then there's "03 Mode" and get around 182 KTAS at 17 or so GPH. 1 Quote Link to comment Share on other sites More sharing options...

BlueSky247 Posted September 11 Report Share Posted September 11 @FJC Those 275's are really growing on me. How long have you had them? Quote Link to comment Share on other sites More sharing options...
FJC Posted September 12 Report Share Posted September 12 I'm going on about 2 years post installation. It was daunting to get them setup and dialed in but now, I really really like them. I have vertical tracking capability with autopilot flying ILS and RNAV approaches which to me is the bomb. I'm still working on optimization of a few items (redundancy of mag for both 275's as an example which will give me heading if I have an electrical loss). 1 Quote Link to comment Share on other sites More sharing options...

I dont have engine parameters other than fuel flow (no temps but no issues at cruise). Yes, I do have air conditioning but almost never need it above 8,000.

Compared to the G5 I am used to, that display is just so much nicer. Quote Link to comment Share on other sites More sharing options...

Paired with a 750/650 and a gfc-500 these are amazing in the soup. 1 Quote Link to comment Share on other sites More sharing options...
