27 Description
28  Look-up based profile data - drag and lift coefficients are lineraly
29  interpolated based on the supplied angle of attack
30 
31  Input in list format:
32 
33  data
34  (
35  (AOA1 Cd1 Cl2)
36  (AOA2 Cd2 Cl2)
37  ...
38  (AOAN CdN CdN)
39  );
40 
41  where:
42  AOA = angle of attack [deg] converted to [rad] internally
43  Cd = drag coefficient
44  Cl = lift coefficient
