Hindustan Aeronautics (HAL) is set to deliver four Dhruv NG helicopters to Pawan Hans as it expands its civil aviation business. Pawan Hans ordered 10 of the multi-role helicopters in January, while the remaining six are expected to be delivered during the current financial year. The delivery plan forms part of HAL’s effort to increase the share of non-military business in its turnover from 5 per cent currently to 25 per cent over the next decade.
