Flight Test Procedure for N600LW
DISCLAIMER: I am NOT a test pilot, nor am I an aeronautical engineer. While I believe that everything on this page is reasonable for a flight test, I don't know what I am talking about, and therefore, if you are about to test fly a brand new airplane, please do not assume that this is the best way, or even a correct way, to conduct a flight test. You MUST consult a qualified, experienced test pilot before test flying your airplane.
GOALS: The purpose of this web page is not to tell you how to do all of the initial flight testing of a newly completed amateur built experimental airplane. The first stage of flight testing a homebuilt airplane is to make sure it is controllable throughout its performance envelope. When I purchased N600LW, it already had 197 hours of flight time, including the hour of flight time I had with the previous owner in the pre-purchase flight. Rather, in this page, I am attempting to conduct flight tests to determine the performance characteristics of N600LW:
- At what speed does N600LW stall?
- Based upon the stall speed, what is a reasonable approach speed?
- What power settings are necessary to obtain this approach speed at a reasonable rate of descent?
- What is Vy for this airplane?
- What speeds can I expect to see in cruise flight at various altitudes and power settings?
- What are the corrections to convert indicated airspeed (IAS) to calibrated air speed (CAS)?
- How much fuel will I burn climbing to cruise altitude?
- How much fuel will I burn in cruise flight?
- What are the appropriate speeds for emergency procedures (Va, airspeed for best glide, airspeed for minimum sink, etc.)?

Performance Results for N600LW Note: This is NOT an acceptable substitute for determining the performance characteristics of your own airplane, EVEN IF it is also a Falcon XP, like N600LW.
