Proposal of an automatic Flight Time measurement method for small aircraft using a built-in smartphone 3-axis accelerometer

This paper proposes a method for obtaining the Flight Time of Small Aircraft from acceleration using a 3-axis acceleration sensor with a built-in Smartphone. In recent years, the use of GNSS(Global Navigation Satelite System) has been successful, and it was listed as a candidate this time, but there are some errors and there is a history of giving up. The conventional method had many individual errors because it is recollected by the Captain. The proposed method can be easily and inexpensively upgraded. In the experiment, an actual Small Aircraft was used and acceleration data was acquired assuming actual flight. We were able to fly 5 times because we could not fly freely due to control. Excel and total software R were used for data analysis. The number of flight was 5, but the number of samples was more than 30,000 in one flight. Since the phenomena in the natural world follow a normal distribution, we calculated the threshold with a 99% confidence interval. R was used for curve analysis of the normal distribution. As a result, it was found that false detection occurred at a rate of 0.5% in the proposed method. © 2021 The Institute of Electrical Engineers of Japan.
