Lucknow: Hindustan Aeronautics Limited (HAL) received the modification document of HAL Do-228 (upgraded) civil aircraft for 5,700 All Up Weight (AUW) from the Directorate General of Civil Aviation (DGCA) during the ongoing DefExpo-2020 on Thursday.
The document was handed over by DGCA's JDG G Rajsekhar to HAL's General Manager (Transport Aircraft Division, Kanpur) Apurba Roy in the presence of HAL's CMD R Madhavan and senior executives from HAL and DGCA.
Two Civil Do-228 produced by HAL for launch under UDAN scheme having state-of-the-art configuration certifications from DGCA for MTOW at 6,200 kgs. But in order to meet the prospective operators requirement of a transport aircraft flyable under the commercial pilot license (CPL) category, HAL undertook efforts to reduce the aircraft weight below 5,700 Kgs.
Apart from weight criterion, HAL Do-228-201 (Upgraded) civil aircraft will also be equipped with the 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 a 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 result in a significant reduction in noise levels, faster engine start, less lubrication and better damping characteristics.
