What are FDTL, part of chaos due to hundreds of IndiGo flights' cancellations?
IndiGo's cancellation of hundreds of domestic flights this week is partly because the airline failed to adhere to the government's updated flight duty time limitations (FDTL) regulations. FDTL set boundaries for pilots' working days, the rest they must be given between duties, and limit late-night and early-morning operations. They're put in place to avoid pilot fatigue, ensuring flight safety.
