AIDA Recorder

SWIFT-AIDA-Recorder

The AIDA system is a modern Data Acquisition System, originally developed for the military Lynx helicopter. The system covers the monitoring and time-referenced signal recording and analysis of more than 10 signals such as the rotary speed of the main rotor, speed of high- and low pressure turbines, drive torque, the angle of bank, the airspeed, the load on the sponsons, exceedance of minimum height for radar measurement, exact determination of the rotor start / stop cycles and the estimation of the life time of the turbines.

Also acoustic and optical warning signals for the pilot can be activated when the maximum rotation speed of the main turbine is reached, or in case the radar height measurement falls below a minimum level and for excessive stress loads on the landing gear. It has been proven that the AIDA recorder provides higher flight safety, extends the inspection intervals for all mechanical parts of the air craft and considerably reduces the aircraft service costs. Typical applications include the determination of start and landing weights, measurement of actual flight hours, load at landing, determination and analysis of manoeuvres and incidents.
