Hi All, I was on IRC a while ago asking about the acceleration information available from FG through the FGInterface class. I particularly would like to know what all those various acceleration values mean. I am interested in an output as would be that of a 3-axis accelerometer placed on the aircraft. i.e. The acceleration of the aircraft is in addition to the acceleration due to gravity.
I did a little experiment to read the values obtained through the API's and at a point when the plane was in a dive and almost nose dive, the acceleration due to gravity should have shifted from z axis to the x axis, but this does not seem to be the case. Can anyone throw more light on the subject? These are the outputs when i was nose diving. get_V_dot_north() = 0.000000 get_V_dot_east() = 0.000000 get_V_dot_down() = 0.000000 get_U_dot_body() = -0.367781 get_V_dot_body() = 0.487957 get_W_dot_body() = 20.238091 get_A_X_cg() = 0.000000 get_A_Y_cg() = 0.000000 get_A_Z_cg() = 0.000000 get_A_X_pilot() = -0.393838 get_A_Y_pilot() = 0.497553 get_A_Z_pilot() = 20.254851 get_N_X_cg() = -0.011425 get_N_Y_cg() = 0.015158 get_N_Z_cg() = 0.628668 -- Cheers! kitts ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
