Just a comment on the Intersema sensors ; they are quite good and very
useable, but not great for an IMU based system, the sample rate (35ms) is a
little on the long side. 50Hz is really the slowest you want to sample
airdata when integrating into a Kalman filter based IMU/INS. However, on a
basic system in Paparazzi it will work quite well, especially if using an
inherently stable airframe.

Hi all, 
I just wanted to let you know that one can also use digital barometric
sensors such as intersema ones.
The code is already done for the paparazzi you just have to solder a few
wires to the part and turn the code on in the airplane file.
But...as it was already mentionned on a fixed wing the problem is to avoid
dynamical pressures...
Good luck !
Cédric
