Did some of you ever made some speed records on your DA40?
I did it with a friend on his UL VL3 because he wanted to optimize the settings of his fixed prop pitch and I want to do the same in order to have the real performance of my own DA40.
What do you recommend ?
My idea (based on what we did with my friend and his UL) is to record values at different altitude, on 3 legs (heading +120 degrees each) and make an average of the values recorded on each of the 3 legs at a given altitude.
Values to record:
-Indicated airspeed (approx because I have a steam gauge)
-Ground speed (on my GPS)
-QNH of the location
-Heading (0 / 120 / 240)
-Outside air température of each altitude
-Altitude (2000 ft / FL075 / FL115)
-RPM/MP/FF (eventually I will make the record with different configuration on RPM/MP/FF)
-Weight of the aircraft (I don’t know how it influences the speed performance, any idea?)
What do you think? Choice of the values to record? Choice of the altitude / FL...
Any advises before making this test are welcome.
