Jetstar is equipping its fleet of A320 and A321 aircraft with Required Navigation Performance (RNP) to improve safety and on-time performance.

The satellite-linked navigation system will enable aircraft to safely navigate around cloud-shrouded mountains, through valleys and over high terrain when low visibility will increase the chance of flight disruptions, the airline said.

The airline conducted year-long trials of the system at Coolangatta, Brisbane and at New Zealand's worst weather-affected airport, Queenstown.

Results from the tests showed that aircraft equipped with RNP maintained a high degree of accuracy during instrument assisted landings, the airline added.

The airline is investing Australian dollars (A$) 6 million ($6.4 million) in the technology and is expecting Jetstar's Australian and New Zealand fleet of A320s to be fitted with RNP by the end of 2012.
