![]() ![]() I should use this chart if my altimeter is calibrated to 25.0 IN.HG or more and my RPM is 2100 maximum. I don't know if I understand this well or not. Okay, that is what I use to calibrate the altimeter.Īnd finally the RPM. I see there are charts for Inches of Mercury IN.HG. My second doubt is about the title of the charts. in that case I guess I must use the RICH MIXTURE CHARTS. I am descending, I am close to the runway and my MIXTURE IS FULL RICH. In that case I think I should apply LEAN MIXTURE CHART? normally at that altitude I would have the red lever almost back, to a 23%, so it is clear my mixture is lean. My first doubt is about what criteria should I apply to decide if I use a LEAN MIXTURE CHART or a RICH MIXTURE CHART. I see LEAN MIXTURE CHARTS and RICH MIXTURE CHARTS. However, here I have several charts for cruise performances. so I find the range 10000 feet -8 Fº TO 10000 feet 28 Fº so accoring my exterior tempo, I find in that range the proper speed as indicated in the table. I know I would have to look first the altitudes in the table 10000 feet and then the temp. I also know how to match the altitude and the temperature in the charts, so if I fly to 10000 feet and I have 69 Fº for the outside temp. I know how to lean the mixture and how to get the EGT peak by monitoring the EGT instrument (Exhaust Gas Temperature). First, I'd like to say what I know how to do. LEAN - 25.0 IN.HG (OR FULL THROTTLE) 2500 RPM - CRUISE LEAN MIXTURE RICH - 25.0 IN.HG (OR FULL THROTTLE) 2500 RPM - CRUISE RICH MIXTURE ![]() LEAN - 23.0 IN.HG (OR FULL THROTTLE) 2300 RPM - CRUISE LEAN MIXTURE RICH - 21.0 IN.HG (OR FULL THROTTLE) 2100 RPM - CRUISE RICH MIXTURE LEAN - 21.0 IN.HG (OR FULL THROTTLE) 2100 RPM - CRUISE LEAN MIXTURE ![]() ![]() LEAN - 25.0 IN.HG (OR FULL THROTTLE) 2100 RPM - CRUISE LEAN MIXTURE RICH - 25.0 IN.HG (OR FULL THROTTLE) 2100 RPM - CRUISE RICH MIXTURE Hi, I have several cruise performances but I really don't know very well how to deal with them. ![]()
