Exam-focused facts from the 3 July 2026 current affairs briefing.

Key facts

  • The Directorate General of Civil Aviation (DGCA) conducted the first satellite-based landing system (SLS) approach on a jet engine aircraft in India.
  • The exercise was carried out using an IndiGo Airbus A320 at Udaipur airport.
  • The operation utilised the GPS-aided geo augmented navigation (GAGAN) system, jointly developed by the Indian Space Research Organisation (ISRO) and the Airports Authority of India (AAI).
  • The aircraft successfully executed a Localiser Performance with Vertical Guidance (LPV) approach, which was previously limited to turboprop aircraft in India.
  • GAGAN is a Satellite-Based Augmentation System (SBAS) that reduces dependence on ground-based Instrument Landing Systems (ILS), especially at airports without precision landing infrastructure.
