The relaxation came following en masse IndiGo flight cancellations and delays, leading to a collapse and chaos in the aviation sector. Highlighting that the relaxation has “increased accident risk, pilot fatigue exposure”, the petitioners have also objected to Indigo and other airlines marketing themselves as “low cost airline”. It is only that at the moment, there must be some rationale available with DGCA (for putting the norms in abeyance),” CJ Upadhyaya added orally. The new FDTL rules were implemented in two phases to better manage pilot fatigue, a key risk to aviation safety. The exemptions also allow IndiGo pilots flying during these hours to perform up to six landings, whereas the new norms capped night landings at just two.
