DESCRIPTION:

The Integrated Multi-Function Probe (IMFP®) provides Angle of Attack (AoA), Indicated Total Pressure (Pt), and Indicated Static Pressure (Ps). It provides AoA by sensing the direction of the local airflow and has ports for impact and static pressure on the rotating sensor probe to calculate Pitot / Static, Airspeed, Mach number, and Altitude.

OPERATION:

The IMFP® is mounted on the fuselage with the sensing probe extending through the aircraft fuselage. The sensing probe is continually driven to null pressure differential between the upper and lower slots in its forward surface. These features sense the direction of airstream flow (Local AoA). The angular position of the sensing probe is
converted to an electrical output by an angular sensor.

 (See Outputs) The pressure at the center slot of the sensing probe is ported to a highly accurate and stable pressure transducer (Pt). The pressure at the slots is correctable static and is ported to the highly accurate and stable pressure transducer (Ps).
