Greenfield Airport in Pakyong, which has been stalled from operations since end of 2019, has been declared open for operations from January 23. SpiceJet, so far, is the only airline that has been onboard in Pakyong and for the future as well, it seems like it will the only airline catering to Delhi and Kolkata as declared earlier by the airline.
There is a specific technical reason for the same. With its high-altitude, table-top runway, Pakyong has for long struggled with visibility concern, resulting in air operations being stalled after a year-long operation since October 4, 2018. Now, to ease the visibility concern, Airport Authority of India has reached a consensus with Directorate General of Civil Aviation to introduce Required Navigation Performance System, specific to Pakyong Airport only in the country.
Required navigation performance (RNP) is a type of performance-based navigation (PBN) that allows an aircraft to fly a specific path between two 3D-defined points in space. A navigation specification that includes a requirement for on-board navigation performance monitoring and alerting is referred to as an RNP specification. Therefore, if ATC radar monitoring is not provided, safe navigation in respect to terrain shall be self-monitored by the pilot and RNP shall be used. RNP also refers to the level of performance required for a specific procedure or a specific block of airspace. An RNP of 10 means that a navigation system must be able to calculate its position to within a circle with a radius of 10 nautical miles.
