The Transport Aircraft Division of Hindustan Aeronautics Limited (HAL), based in Kanpur (India) recently developed a civil version of the HAL-DO-228, upgraded with a new 5-bladed propeller. Anotec was contracted by HAL to perform the noise certification of this new aircraft version under ICAO Annex 16, Chapter 10 rules and under Indian DGCA supervision. The flight test campaign was conducted at Kanpur Airport with the Anotec mobile lab in collaboration with the HAL-TAD flight test department. Data analysis was performed on-site and the approval of the final report was obtained from DGCA soon after.
