The RNP AR system enables aircraft to follow predetermined flight paths with high accuracy, effectively reducing risks associated with the mountainous landscape
IndiGo announces the introduction of the Required Navigation Performance Authorization Required (RNP AR) flight procedure for its operations into Kathmandu. IndiGo successfully operated the validation flight on September 4, following the clearance received, in line with the provisional approval by DGCA. This implementation of technological advancement represents a major step forward in aviation safety and efficiency, enabling the pilots to navigate the complex terrain surrounding Kathmandu Valley with precision.
RNP AR technology is specifically engineered for airports situated in geographically challenging and high- altitude regions, such as Kathmandu’s Tribhuvan International Airport (KTM). With the airport surrounded by the Himalayas, landing in Kathmandu has traditionally been a challenge for pilots, particularly during adverse weather conditions. The implementation of the RNP AR system enables aircraft to adhere to predetermined flight paths with remarkable accuracy, effectively mitigating the risks posed by the mountainous landscape.
IndiGo’s adoption of the RNP AR procedure for all flights into Kathmandu will significantly enhance passenger safety. This advanced navigation capability supports continuous descent approaches, thereby optimizing airspace usage, reducing fuel consumption, and minimizing emissions.
Capt. Ashim Mittra, Senior Vice President Flight Operations, IndiGo, said, “With the implementation of the RNP AR flight procedure, IndiGo reinforces its dedication to leading the industry in aviation safety and operational efficiency, ensuring safer and more reliable skies for all travelers.”
