Abstract
Abstract THE RATIO BETWEEN A CHANGE IN LOCAL AIRSTREAM DIRECTION AND THE CORRESPONDING CHANGE IN A RESULTANT OUTPUT REPRESENTING "NORMALIZED ANGLE OF ATTACK" IS VARIED AS A FUNCTION OF FLAP POSITION AND THE RESULTANT OUTPUT IS BIASED AS A FUNCTION OF FLAP POSITION SO THAT THE RESULTANT OUTPUT REPRESENTS ZERO "NORMALIZED ANGLE OF ATTACK" WHENEVER THE COMBINATION OF FLAP POSITION AND LOCAL AIRSTREAM DIRECTION IS SUCH THAT THE AERODYNAMIC LIFT IS ZERO AND SO THAT THE RESULTANT OUTPUT REPRESENTS 100 PERCENT "NORMALIZED ANGLE OF ATTACK" WHENEVER THE COMBINATION OF FLAP POSITION AND LOCAL AIRSTREAM DIRECTION IS SUCH THAT A FURTHER INCREASE IN ANGLE OF ATTACK WOULD RESULT IN STALLING OF AIRCRAFT. THE RESULTANT OUTPUT REPRESENTING "NORMALIZED ANGLE OF ATTACK" IS UTILIZED FOR INDICATION OR CONTROL PURPOSES.
