The Technology Development Fund of the Defence Research and Development Organisation (DRDO) is actively seeking collaboration with Indian private sector companies to develop a Wireless Aircraft Flight Data Recorder (FDR) system. This system is designed to wirelessly transmit and receive data from the aircraft’s data recorder to a ground station, eliminating the need for manual data transfer.

The Flight Data Recorder is a critical component that stores crucial parameters captured by various sensors during a flight. These parameters include data on vibrations, engine performance, and control surface status, among others. The aircraft recording and monitoring system encompasses the storage and processing of data collected from these embedded systems and sensors. In modern fighter aircraft, three flight data recorders are typically installed at different locations within the aircraft.

Traditionally, data from the flight data recorders are manually transferred through storage devices to a ground terminal for analysis of sensor health and performance. However, this method can be time-consuming, prone to errors, and cumbersome, particularly when managing large fleets. The introduction of wireless data transfer would streamline the process and significantly reduce turnaround time for aircraft missions.

By developing a wireless FDR system, DRDO aims to enhance operational efficiency and ensure timely access to critical flight data. The wireless transmission of data from the aircraft to the ground station will enable real-time monitoring, quicker analysis, and faster decision-making. This technological advancement is particularly beneficial for managing large fleets and expediting maintenance and operational processes.
