Doppler speed test?
Hi guys
Can one of you guys with the doppler program see if you can get a reading off this audio please? Plane is a Hangar 9 Jackal Jett 56LX turning an APC 9-8 prop....wind out of the north 5mph (headwind) [link=http://www.cvrcclubvideos.us/SDVids/SpeedTest.wmv]Video[/link] |
RE: Doppler speed test?
There is actually a speedometer app for the Iphone that uses the doppler effect to calculate the speed of your plane I downloaded it yesterday but have not yet had the chance to test it.Unfortunatly it didnt work for the video so i hope it will work in real life.

RE: Doppler speed test?
Managed to get two readings(a big source of error is the air-temperature, I set it at 90F.)
At 0:22 I got 111,4MPH and 84MPH at 1:03. Don't know how reliable it is. Would have guessed that a jackal with that setup would be faster. |
