Lucknow (NVI): State-owned Hindustan Aeronautics Limited today received the modification document from Director General of Civil Aviation for upgrading Dornier-228 civil aircraft by reducing its gross weight below 5,700 kg.
The development took place on the second day of DefExpo-2020 in Lucknow today as the Joint DG of DGCA, G Rajshekhar, handed over the document to HAL.
Under the regional connectivity scheme UDAN, two civil Do-228 were produced by HAL, having state-of-the-art configuration certifications from DGCA for maximum takeoff weight (MTOW) at 6200 kgs. But, in order to meet the prospective operator’s requirement of a transport aircraft flyable under Commercial Pilot License (CPL) category, HAL undertook efforts to reduce the aircraft weight below 5700 Kgs.
Apart from weight criterion, HAL Do-228-201(Upgraded) civil aircraft will also be equipped with digital cockpit which will ensure more accurate readings, precise information and ergonomic data displays with feedback loops and capability for self-check to alert pilot in emergencies. The Glass Cockpit architecture enabled aircraft will be most sought after new age aviation technology.
Also, the incorporation of civil certified turbo-prop minus 10 Engine ensures more reliable torque sensing system, higher component life, lighter in weight and higher time between overhaul (TBO) as compared to previous minus 5 engine.
It is also assured that the integration of the five-blade propeller to HAL Do-228-201(Upgraded) aircraft will augment in a significant reduction in noise levels, faster engine start, less lubrication and better damping characteristics.
