Based on the performance charts you will know the fuel burn per hour as well as the calibrated air speed. It is however very easy to estimate fuel burn and range once you completed your pre-flight preparations. You may as well get a "mileage" of 12 or 25 miles per Gallon at exactly the same settings - depending on whether you have a strong headwind or tailwind. You won't get a mileage though with an airplane, as the range of an airplane depends much more on weather conditions than the range of a car. Fuel burn depends mainly on manifold pressure, propeller RPM and pressure altitude and is measured in Gallons/hour or Litres/hour. You will find the fuel burn table in the Performance manual.As described in the manual (and ideally standard knowledge for any rider of motorized vehicles!?!?) the W40 oil is rather for higher temperatures whereas the W20 oil is less "thick" and thus more adequate for lower temperatures You can find the exact recommended tempertures in the Katana manuals. There are no two different "oil brands", however two oils with different viscosity.Again, check the maintenance module for areas of concern. Or it could be the wrong fuel, or it might be related to the oil pressure and you have abused the engine by flying it at high power settings when cold - this will make it difficult to start. ASSUMING THERE ARE NO FAULTS YOU ARE FLYING IT WRONG.įor engine start, follow the procedure.You are missing something in the checklist - fuel pump, choke (depending on hot or cold start) slight throttle open (again, depending on hot or cold start), forgetting to warm the engine properly, not using the baffle in cold weather, or using it in hot, etc. The manual specifically states that oil pressure will advance in the yellow arc until the oil reaches normal operating temperature. So you need to be systematic:Ģ: Check oil type is correct for the prevailing weather conditionsģ: Check maintenance isn't giving you red or yellow flag on the engine or oilĤ: If you are flying in cold conditions, put the baffle inĥ: Ensure you warm the engine properly before flying All of these things are properly simulated in the Katana X. As in real life high oil pressure means either the wrong oil, wrong oil level, a partial blockage, or the oil is cold. ![]()
