MANILA, Philippines – The Civil Aviation Authority of the Philippines (CAAP) assured the public that the replacement of navigational equipment at the Ninoy Aquino International Airport (NAIA) will cause no disruption to operations and daily flight schedules.

CAAP Bids and Awards chairman Rodante Joya said the project is expected to be completed in 270 days, with an expected downtime of the existing system for only 35 days.

The target date of completion is August this year.

Joya said the procedure will take a long time to complete due to necessary infrastructure work.

There should be no impact to operations though since NAIA operates on redundant navigational equipment.

According to CAAP Deputy Director General Capt. John Andrews, while the DVOR or Doppler VHF Omnidirectional Range is down, 2 other systems, including the RNAV which uses GPS technology, will kick in to take care of the navigational requirements for landings and take offs.

Andrews added that the replacement of the DVOR should have been done a long time ago.

The existing DVOR system was installed in 1996. Its life term was only 10 years but NAIA has been using it for 18 years.

In 2010, the system failed and flights were diverted to Clark in Pampanga.

The system is supposed to help pilots navigate in bad weather when there is poor visibility.

With the replacement of the system, NAIA's navigational equipment will be more accurate, thus increasing safety of NAIA users.
