Hi guys.
We flied quite a lot of sorties with 4 VTOL vehicles last month and experienced quite scary situation.
There were two cases of over-speeding in two different aircrafts when both of them was set to fly at 20m/s during mission flights.
Is there a reason why the airspeed keeps reseting and what causes the surge of airspeed at certain point? It seeemed airspeed went up when flying in a tail wind. Ground speed was also recorded high and we coudn’t confirm the speed in the monitor was correct or not.
It was quite windy, 8~10m/s, up at the altitude where both aircrafts were flying.
Any advice is much welcomed.
These are GPS speed
aircraft1 speed
aircraft2 speed
Here are Logs of each flights.
