<h1>Regulator proposes tariff-linked performance standards for major airports using 32 objective and 18 subjective metrics</h1> The aviation regulator has published a draft framework proposing uniform, tariff-linked performance standards for major airports, combining 32 objective and 18 subjective parameters to measure quality, continuity and reliability of services; the framework would embed incentives for exceeding benchmarks and rebates for non-compliance into tariff regulation. Targeted at airports handling over 1.5 million passengers, the proposal emphasizes technological monitoring, user-centric metrics and enforceability to address regulatory asymmetry where competition is limited. Stakeholder comments are invited until the specified deadline as the regulator aims to harmonize oversight across major airports.
