Our plane can not fly fast therefore our speed variation is low.
Thank you for the sensor recommendation.

Konu: Re: [Paparazzi-devel] airspeed_ets calibration
can you fly with a special flight plane at different speed over ground with wind and again the wind and the calculate the TAS with the true speed over ground from the GPS?
Martin was calculating the wind speed by flying circles with constant throttle and pitch.
I found a temperature dependence for the accelerometer of the MPU60x0 and the bmp085 to.
The MPU60x0 has a temperature sensor on the chip as the bmp085. The BMP085 is heating up for 3-5°C over the air temperature.
I found that the temperature from the autopilot pcb was vary strong (about 20°C).
There are other pressure difference sensors working inside by difference temperature flow. This sensors have no temperature drift but are expensive about 80 Euros.
The interface is i2c.
