About the speed value in the flight data showing high speed of upward 70  to 80 miles per hour. Some people suggested that it is a bug. It is  kind of...

Today I went flying with the P4P, P4P PLUS and the MAVIC PRO. I watched  the speed on the screen while I was flying and I reached around 47.8  miles/hr.

My flight data from the APP showed 75.5 miles per hour... BUT IT IS  actually 75.5 KILOMETERS per hour when you convert 47.8 mile to  kilomerters.

Please do some flying, keep an eye on the speed on the APP while flying,  then go to the flight data records and then convert the speed to miles  per hour and let me know what you find out

This has been a known issue for a long time. At least 2 months. Lots of threads have covered this.

I know... but now we know why instead of kilometers they use miles even though you set the speed to read in imperials/
