Take-Off Conditions

Using the same linearized lift curve, find the take-off incidence, {aeq)t_o in deg corresponding to CLm = 1.9.

Show that at take-off, the tail has positive lift (Hint: calculate the tail setting angle (tt )t-o at take-off). Extra Credit

Sketch the forces and forces locations at take-off with respect to the aerodynamic centers of the main wing (xacm/lref = 0.27), of the tail (xact /lref = 0.83), of the complete configuration (xac/lref) and with respect to the center of gravity, given that there is an 8 % static margin.
