IndiGo, India’s largest airline, is adding upgrades of required navigation performance with required authorization (RNP AR) to some of its A320neo aircraft.

NavBlue, an airbus and air traffic control IT company, is upgrading the RNP AR for IndiGo A320 to give Indian carrier pilots the ability to “navigate mountainous areas or other complex airspace with accuracy and predictability,” according to Feb 15 ad on the update. RNP AR is an advanced performance-based navigation (PBN) approach that requires operators to obtain prior authorization from civil aviation authorities. Advanced navigation technology allows the aircraft to fly a predetermined path between waypoints by placing the approach to the airport on a curved precise trajectory, where the descent and positioning are constantly complemented by satellite navigation signals.

Ronojoi Dutta, CEO of IndiGo, said the upgrade will allow IndiGo pilots to “safely pass through difficult terrain such as curved or hilly areas during takeoff or landing. We believe this will improve the operational safety of the aircraft as well as increase efficiency in the long run.” “

Kathmandu is one of the airports where IndiGo sees that updating the RNP AR provides some immediate benefits, as the mountains and terrain surrounding the airport can make the approach and landing process more difficult. The performance-based navigation update (PBN), which is added to the A320neos, allows you to get navigation accuracy up to 0.3 NM and below, as well as turns after the end point of the approach, according to NavBlue.

NavBlue describes it RNP AR update as a “glass” solution that includes support for aircraft upgrades, development of procedures and verification of the navigation database, and support for flight crew training.

IndiGo is also acquiring a standalone receiver integrity monitor (RAIM) prediction service from NavBlue that allows pilots to use the latest available GPS satellite constellation information to calculate mask angle, fault detection, sample availability and bearded aspects of using RNP AR-based updates.

“For complex airports where RNP AR approaches or departures are used, predictions along the route use a real angle mask to account for terrain,” NavBlue reports.

The RNP AR update for IndiGo comes after their release on February 4 in the third quarter of fiscal year 2022 salary results, with the airline reporting its first quarterly profit – 1.3 billion rupees – in two years. IndiGo also expects to replace most of its A320ceo fleet, which is in operation, with the A320neos by the end of 2022.
