Air Data Unit
The Air Data Unit measures pitot airspeed and barometric altitude in fixed-wing aircraft.
The Air Data Unit is used to measure pitot airspeed and barometric altitude in fixed-wing aircraft. It features high accuracy temperature calibrated pitot and static air data sensors and outputs data over RS232. It can be used standalone or connected to one of Advanced Navigation’s INS products for outstanding navigation accuracy in fixed-wing aircraft when GNSS is not available.
Features
Temperature Calibrated Pressure Sensors
The Air Data Unit features very high accuracy absolute and differential pressure sensors. These are factory calibrated over a wide temperature range to further increase measurement accuracy and provide the best air data possible through varying conditions.
Power Up Self-Calibration
On top of factory temperature calibration, every time the air data unit powers up, it performs a self excitation calibration to adjust for small deviations of bias and scaling error. This allows the system to compensate for calibration aging and means that it never needs to be returned to the factory for recalibration.
Reliability
The Air Data Unit is built on top of a safety oriented real time operating system and all software is designed and tested to safety standards with fault tolerance. Its communication interface is optically isolated and the hardware is designed and tested to MIL spec.
