The Directorate General of Civil Aviation (DGCA) on Friday eased certain pilot duty regulations with immediate effect after low-cost carrier IndiGo experienced a major staffing shortfall, leading to the cancellation of hundreds of flights nationwide, reported the IANS.

In a bid to contain the escalating crisis, the aviation regulator issued a fresh notification granting partial relief on flight crew duty norms, specifically relaxing a rule that prevented airlines from combining leave with weekly rest periods.
