AEROSONIC® manufactures aviation instrumentation and avionics equipment including air data systems, standby displays, digital and mechanical standby instruments, sensors and probes. The company has an extensive portfolio of pitot probes (including pitot, pitot static and pitot/angle-of-attack probes) static pressure ports and stall warning transmitters (SWT) meeting the requirements of virtually any type of aerospace application. A brief presentation of their features and applications is included below.
Pitot / Pitot-Static Probes
AEROSONIC® has an extensive portfolio of pitot-static probes, which supply both pitot and static pressures in a single device. AEROSONIC®'s Pitot-Static Probes are designed with rugged heating elements to prevent ice accretion and water ingression for reliable operation in the most adverse environmental conditions and meet or exceed all applicable standards, including SAE AS393, DOD MIL-T-5421B/20B, AA TSO-C16, TSO C-16B (pitot-static probes), AN5813 and BS2G.135. Probes may be configured as stand alone with pneumatic outputs to the Air Data Computer, or they may integrate the computing function and eliminate the pneumatic connection.

AEROSONIC® FAA approved commercial pitot probes and pitot-static probes are installed on virtually every major commercial platform, including the Boeing 737, 757, 767 &777. Available for most major commercial platforms, they meet or exceed existing icing standards. Several enhancements made to improve corrosion/erosion resistance & extend service life.
Angle-of-Attack Probes
The Angle of Attack (AoA) Probe provides AoA or Sideslip (SS) by sensing the direction of local airflow. It 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 air stream flow (Local AoA or SS). The angular position of the sensing probe is converted to an electrical output by an angular sensor. AEROSONIC AoA Probe features include:
Angular Range +/-50˚
Resolution 0.04˚ or less
Calibrated Accuracy +/-0.25˚
Speed Range up to 1000kts
Mechanical Threshold 80-120kts 0.2˚;>120kts 0.1˚
DO160 Environment
MIL704 Power
BS3G100 Environment
BS3G100 Power
Outputs: Single, multiple and mixed, Potentiometers, RVDT’s, ARINC 429, Max weight: 3.0 lbs
Static Pressure Ports
AEROSONIC® fuselage mounted Static Pressure Ports are engineered to meet or exceed industry specifications to supply ambient static pressure measurements to air data computers, altimeters, airspeed indicators and vertical speed indicators in numerous types of aerospace applications. The Static Pressure Ports’ electrical heating elements prevent ice accretion and water ingestion ensuring the performance of primary flight instruments is not degraded even under the most severe atmospheric conditions.

Stall Warning Transmitter (SWT)
The Stall Warning Transmitter (SWT) is an Angle of Attack (AoA) Probe fitted with a built in Stall Warning Computer. The SWT provides Local and Normalized AoA signals for indicators, multifunctional displays, and flight control systems. It also provides outputs for audio warnings, stick shakers, and stick pushers at the appropriate time of the flight envelope. It accepts signals from flaps, spoilers, speed brakes, and other control surfaces and uses them to modify the stall warning characteristic curves. AEROSONIC SWT features include:
Angular Range +/-45˚
Resolution 0.04˚ or less
Calibrated Accuracy +/-0.25˚
Speed Range up to 1000kts
Mechanical Threshold 80-120kts 0.2˚;>120kts 0.1˚
