[Paparazzi-devel] Bug in rotorcraft thrust coefficient estimation

Hi,

   In the function "get_vertical_thrust_coef"  defined in "rotorcraft/guidance/guidance_v.c " . 30 deg has been compared with the last entry of rotation matrix att->m[8]. But last entry[i.e 9th entry] in the rotation matrix is Cos(X), where X is the angle between the gravity vector and thrust vector. 
   Is last entry of rotation matrix is intended to compare wth cos(30deg) instead of 30deg ? 

Thanks, 
srinath
