For example, in smooth water and medium air, if the main is trimmed such that its lift-to-drag ratio decreases, that loss could be more than offset by a higher angle of attack from the rudder, or ...

For high angles of attack, the aerodynamic center moves aft for all configurations, an expected consequence of separation. Changes in CN, normal force coefficient, are similar to changes in lift. CS, ...

After an extensive evaluation process, FlightSafety has chosen Safe Flight Instrument Corp. to equip more than 30 airplanes in its Piper training fleet in Vero Beach, Florida, with head-up angle ...
