Flight Report for flight:201 #109

Open claireleblay opened 3 months ago

claireleblay commented 3 months ago

According to the report : avgAirSpeed: 273.38 m/s flightDistance: 246.63 m flightDuration: 00:12:36 so 756 s windSpeed: 24.05 m/s

According the wiki (Question : mach speed and wind_speed #30) "Air speed is the speed reported by the instrument on board ( as measured by an anemometer ) ground speed is the speed you compute from the gps coordinate wind speed is just the difference"

So the ground_speed = air_speed - wind_speed = 273.38 - 24.05 = 248.33 m/s So the distance shoud be 248.33 m/s * 756s = 187737.48 m which is different from 246.63 m

Am I missing something ?

Samsies, Flight Distance doesn't match the supposed result... Which method is being used for the calculation of the flight distance in the flight report ? Haversine ? Does it take the curvature of the earth into account?

Flight distance ai d ground speed should be computed from the integration of longitude and latitude coordinate. Air speed is the speed of air relative to the wing, this is only useful to compute lift or drag or other similar things. "wind speed" is the difference in norm to approximate the actual speed of the wind. It hints t the weather conditions during the flight
