1. A system for determining angle of attack and angle of sideslip of an air vehicle, said system comprising:
- a plurality of mass air flow sensors, at least a portion of which are mounted to result in a differential in air flow across respective said mass air flow sensors; and
a controller configured to receive signals from said flow sensors and determine at least one of the angle of attack and the angle of sideslip for the air vehicle.

Abstract
A system for determining angle of attack and angle of sideslip of an air vehicle is described. The system includes a plurality of mass flow sensors, at least a portion of which are mounted to result in a differential in air flow across the respective mass air flow sensors. The system also includes a controller configured to receive signals from the flow sensors and determine at least one of the angle of attack and the angle of sideslip for the air vehicle.

8. A method for determining one or more of angle of attack and angle of sideslip for an air vehicle, said method comprising:
-
receiving air flow data from a plurality of mass air flow sensors, at least a portion of which are positioned to result in a differential in air flow across the portion of the sensors; determining, using a controller, at least one of the angle of attack and the angle of sideslip for the air vehicle from the received air flow data; and providing the at least one of the angle of attack and the angle of sideslip to at least one of an external system and an external user interface. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An air flow mass sensor system comprising:
-
a probe comprising a plurality of flow ports formed therein, a first plurality of said flow ports positioned to create a differential airflow therethrough based on an angle of attack of an air vehicle, a second plurality of said flow ports positioned to create a differential airflow therethrough based on an angle of sideslip of the air vehicle; a plurality of mass air flow sensors, a first of said mass air flow sensors positioned within a path created between said first plurality of said flow ports, a second of said mass air flow sensors positioned within a path created between said second plurality of said flow ports; and a controller configured to receive signals from said flow sensors and determine at least one of the angle of attack and the angle of sideslip for the air vehicle based on the differential air mass flows through said flow ports. - View Dependent Claims (16, 17, 18, 19, 20)
