Opening of North-South expressway

From 7:00 a.m. on August 18, the "high-speed, parallel, one-way North-South flight system" was officially put into operation under the supervision of the Civil Aviation Authority of Vietnam.

Vietnam Air Traffic Management Corporation (VATM) said that this unit officially put into operation the "High-speed, parallel, one-way North-South route system", based on advanced navigation features (RNAV5) starting from August 18.

According to the Vietnam Air Traffic Management Corporation, the current flight path on the North-South axis is a two-way flight path with limitations due to the high volume of aircraft operating, large intersections, and aircraft operating on the two-way flight path frequently changing altitude to avoid each other.

Therefore, in recent times, the Civil Aviation Authority, VATM and relevant military agencies have been researching and building a system of high-speed, parallel, one-way North-South routes based on advanced navigation features (RNAV5) according to the standards of the International Civil Aviation Organization (ICAO).

The "high-speed air route" diagram parallel to the North-South flight axis has been in operation since August 18.

This one-way parallel flight system is being applied by advanced countries in the world to prioritize long-distance flights at optimal altitudes; the modern, popular type of aircraft today is in the form of an air highway between major airports (this flight system is called sky highway in the world).

Previously, North-South planes traveling in both directions shared the same route, avoiding each other based on altitude. However, with the one-way parallel flight path, it is divided into two parallel horizontal routes, one in each direction, and is straighter than the previous flight path.

If this one-way parallel flight path is considered a highway, then planes taking off and landing at airports along the route such as Da Nang and Cam Ranh will enter and exit the highway via the service road. When planes enter the highway, traffic will be faster, the throughput capacity on this flight path will be higher, and air traffic control and pilots will be able to handle situations more easily.

According to VATM, Vietnam's flight information region is located in the center of the corridor connecting key economic regions of West and Southwest Asia with East and Northeast Asia, with the highest flight density and growth rate in the world; annual growth rate of over 17%.

With over 2,000 flights per day in Vietnam’s skies, Vietnam’s flight operations output in 2016 will reach over 730,000 flights. Vietnam’s North-South route is currently ranked as one of the busiest routes in the world, with nearly 700 flights per day, accounting for about 35% of Vietnam’s entire flight network.
