Airports Authority of India (AAI) on April 28 successfully conducted at Kishangarh Airport, Rajasthan flight trial using GAGAN (GPS Aided GEO Augmented Navigation) based LPV Approach Procedures.
- India is the first country in Asia Pacific Region to achieve such a landmark.
Salient features
- Indigo Airlines using its ATR aircraft has flown an Instrument Approach Procedure (IAP) with LPV minima of 250ft, using GAGAN Service.
- The tests at Kishangarh Airport were performed as part of initial GAGAN LPV flight trials along with DGCA team on- board.
About LPV (Localizer Performance with Vertical Guidance)
- LPV is a Satellite Based Procedure which has been used by the aircraft for landing purpose at Kishangarh Airport (Rajasthan).
- LPV (Localizer Performance with Vertical Guidance) permits aircraft guided approaches that are operationally nearly equivalent to Cat-IILS, without the need for ground-based navigational infrastructure.
- The service relies on the availability of GPS and GAGAN Geo Stationary Satellites (GSAT-8, GSAT-10 and GSAT-15), launched by ISRO.
- LPV approaches will make it possible to land at airports not equipped with expensive Instrument Landing Systems, which includes many small regional and local airports
About GAGAN
- GAGAN is an Indian Satellite Based Augmentation System (SBAS) jointly developed by AAI and ISRO. It is the first such system developed for India and neighboring countries in the equatorial region.
- GAGAN System was certified by DGCA in 2015 for Approach with Vertical Guidance (APV 1) and en-route (RNP 0.1) operations.
- There are only four Space-Based augmentation systems available in the world namely India (GAGAN), US (WAAS) Europe (EGNOS) and Japan (MSAS).
- GAGAN is the first such system developed for India and neighboring countries in the equatorial region.
