Aircraft rely heavily on air data computers (ADC) to provide airspeed and altitude parameters that are essential to safe and efficient operation. Rotorcraft experience some unique phenomena because of rotor downwash which can affect the accuracy of pressure measurements and fleets often consist of different aircraft that can create additional logistics overheads.
High accuracy, low drift sensors can be used to provide pilots and autopilots with the information they need to travel at high altitudes safer. The effects of rotor downwash can be alleviated with digital filtering that dreduces the pneumatic noise in air pressure without adding weight like mechanical solutions Multiple aircraft can be fitted with identical ADCs as long as each ADC is capable of holding multiple sets of configuration data to match the target platform.
Curtiss-Wright has developed technologies within its ADC product line to address these needs. High accuracy sensors and decades of experince provide stable data while digital filtering technology mitigate rotor downwash effects. The needs of diverse fleets are simplified with a single unit being usable on up to 15 different platforms through a simple pin-out selection.
