Indian state-owned aerospace and defence company, Hindustan Aeronautics Ltd (HAL) has received Indian Technical Standard Order Authorisation (ITSOA) certificate for its avionic equipment ‘Air Data Computer’ (ADC) with Outside Air Temperature (OAT) Probe’ from the Directorate General of Civil Aviation (DGCA) for the civil platform.

As per the official communique by HAL, the state-run aerospace behemoth has received a certificate for both hardware and software.

For the first time, this feat has been achieved

For the first time in India, the ADC/OAT avionic equipment has qualified for ITSOA certification. The move has paved the way for the fitment on future civil platforms Advanced Light Helicopter (ALH), Dornier, Light Utility Helicopter (LUH), SARAS etc. This major development is an achievement towards ‘Aatmanirbhar Bharat’.

​​The ADC is used to calculate the air data parameters like pressure altitude, calibrated airspeed, Mach number, total air temperature, vertical speed based on static pressure, total pressure, and outside air temperature inputs.

Why is avionic equipment imperative?

Avionic is an amalgamation of “aviation” and “electronics,” the avionics equipment is installed in an aircraft or spacecraft, which comprises engine controls, flight recorders, flight control systems, navigation, communications, lighting systems, threat detection, fuel systems, electro-optic (EO/IR) systems, weather radar, performance monitors, and systems that carry out hundreds of other mission and flight management tasks.

The avionic equipment is used by every modern aircraft, spacecraft, and artificial satellite.

Generally, the more complex the craft or mission is, the more complicated the electronic systems are that they employ.

Commercial airliners, helicopters, military fighter jets, unmanned aerial vehicles (UAV), business jets, and spacecraft all use avionics – to provide services, carry out missions, make new discoveries, track and report performance measures, and operate within established safety parameters.

Further, the most advanced avionics systems also integrate multiple functions to improve performance, simplify maintenance, and contain costs.

About the development of the first ‘Air Data Computer’

Located in Hyderabad, HAL’s Strategic Electronics Research and Development Centre (SLRDC) has indigenously designed and developed the first ‘Air Data Computer ADC 3600A CVL1’ which has environmentally qualified as per DO-160G standard along with in-house developed application software certified as per DO-178C, Level A, required for civil platforms of aircraft and helicopters.
