Transport Aircraft

Avionics Systems

Air data test and calibration systems are used to test and calibrate the pitot tubes and static ports on the aircraft. These instruments measure the pressure and temperature of the air around the aircraft to provide accurate airspeed, altitude, and other related data. They are also used as Airspeed Indicators, to test and calibrate the airspeed indicators on the aircraft, they test and calibrate the altimeters on the aircraft. These instruments are also used as Vertical Speed Indicators to test and calibrate the vertical speed indicators on the aircraft, they measure the rate of change of altitude and provide a visual indication of the aircraft’s vertical speed, and are used to test and calibrate the angle of attack sensors on the aircraft.

• Static Ports: measure the static pressure of the surrounding air
• Pitot Tubes: measure the aircraft’s airspeed

Pressure and Temperature Systems

Temperature, torque, and force measurement instruments are used in Transport aircraft to monitor and evaluate various parameters during operation. They help detect and address any abnormal temperature levels, torque values, or force exertion that may indicate mechanical or operational issues. Accurate measurements from these instruments help maintain optimal performance and safety.
