Two days after Chief Minister Yogi Adityanath declared that the Uttar Pradesh government would purchase Dornier civil aircraft, the HAL on Thursday received the modification document from Director General of Civil Aviation for its Dornier-228 civil aircraft.
The document was handed over to state-owned Hindustan Aeronautics Ltd by DGCA Joint Director General G  Rajshekhar during the ongoing DefExpo-2020 in Lucknow.
Two civil Do-228 aircraft were produced by the aeronautical agency for launch under regional connectivity scheme UDAN. But to meet the prospective operator’s requirement of a transport aircraft flyable under commercial pilot licence, their maximum takeoff weight (MTOW) had to be reduced from 6,200kg.
The HAL said in a statement on Thursday that its engineers undertook efforts to reduce the weight below 5,700 kg.
“Besides, HAL Do-228-201 (Upgraded) civil aircraft would also be equipped with a digital cockpit to ensure accurate readings, precise information and ergonomic data displays with feedback loops and capability for self-check to alert pilot in emergencies,” the HAL statement further stated.
The glass cockpit architecture-enabled aircraft will be the most sought-after ‘new age aviation technology’, it added.
Also, the incorporation of civil-certified turboprop minus 10 engine ensures more reliable torque sensing system, higher component life, lighter weight and higher time between overhaul as compared to previous minus 5 engine.
“The integration of five blade propeller to the aircraft would significantly reduce noise levels, aid faster engine start, less lubrication and better damping characteristics,” said the statement issued by the HAL.
