HAL gets DGCA approval for indigenously developed ‘black boxes’
The Bengaluru-headquartered Hindustan Aeronautics Ltd (HAL) has received the Indian Technical Standard Order (ITSO) authorisation from Directorate General of Civil Aviation (DGCA) for its indigenously developed Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR).
ITSO is a minimum performance standard for specified materials, parts, processes, and appliances used on civil aircraft.
CVR and FDR are popularly known as ‘black boxes’.
They record critical flight parameters and audio environment in a crash proof memory, which are later used for investigation of aircraft incident or accident..
However, these black boxes are painted in orange colour to help in their recovery following an aircraft accident.
