The basic difference between a Static Source and a Pitot is ninety degrees. I just go from there.
I had a chance last week to clamber around an A300. Noticed first of all four Pitot tubes (two on each side, F/O & Alt.; Capt.&Alt). I'm pretty sure that AF447 (A330) has three?). These tubes were unusually (?) long, not sure the significance of that. Each probe appeared to be ~12 inches long.
