INS Hansa – 1st Defence Airfield with RNP approach based on GAGAN Indian Satellite System

INS Hansa has become the very first Joint-User International Aerodrome in South-Asia Pacific region to be augmented with Required Navigation Performance RNP approach. The RNP approach will reduce dependency for navigation on ground-based equipment such as Very-High Frequency Omni Directional Radio VOR and Instrument Landing System ILS. This RNP approach will provide near Category-I ILS accuracies, thereby aiding unhindered flying operations even when the aforementioned equipment are unserviceable/ under maintenance. The capability was achieved through dedicated and concerted efforts of Indian Navy and AAI. A team of AAl officials visited Air Station between 07 - 08 April 2022 towards formulation of Letters of Agreement (LOA) between INS Hansa and Mopa International Airport. During discussions, AAl offered to revise all Instrument Approach Procedures IAPs of INS Hansa and also design RNP approaches for both runways. The station deputed one Instrument Procedure Design Course IPDC qualified officer to AAl and all lAPs were revised with help of Aeronautical Charts prepared by Survey Department of AAI. The AAl also designed Indian satellite GAGAN based RNP approach for runway 26 at INS Hansa Dabolim Airport for which satisfactory flight trials were conducted using station's air assets.
