MANILA -- Remember when almost 100 flights were cancelled in June 2010 because of an old navigational aid that conked out in the middle of a busy day?
Hopefully such incidents will be a thing of the past after the Civil Aviation Authority of the Philippines (CAAP) said the Doppler VHF Omni-Directional Radio Range and Distance Measuring Equipment (DVOR/DME) will finally be replaced with the awarding of the contract to the joint venture of Indra Australia Pty. Ltd. and Philcox Philippines, Inc.
The DVOR is the navigational guidance system that helps pilots locate and land on the runway during bad weather and low visibility. It is very critical, especially at night.
The installation of the new navigational aid will be completed no later than August 2014. The old one was installed back in 1996.
The amount of the supply, delivery and commissioning with flight check is P39,800,205.
The CAAP said the project also includes: the removal of existing DVOR/DME system, underground power and data cables; the installation of new underground power and fiber optic cables; the miscellaneous grounding, electrical and mechanical as detailed on the drawings; and the rehabilitation of existing Doppler counterpoise and shelter system, among others.
The key navigational aid conked out in June 2010, forcing several flights to return to their original destinations or were diverted to other airports.
Initially, the Air Navigation Service of the CAAP saw the problem on the power supply of the antenna tuning unit of the Doppler radar.
