Nigeria Scales Through Satellite Air Navigation Test
Nigeria has passed a pilot test for migration from terrestrial air navigation to a satellite-based navigation, the Nigerian Airspace Management Authority (NAMA) said on Monday.
The Managing Director of NAMA, Mr Nnamdi Udoh, told journalists on Monday, in Ikeja, that the feat was a great one in view of the country’s quest for advancement.
He explained that the satellite-based navigation, Global Navigation Satellite System (GNSS) , was also known as Performance-Based Navigation (PBN).
“Nigeria’s bold attempt to migrate from terrestrial air navigation to a satellite-based navigation system received a boost at the weekend when two foreign airlines tested the new procedure with pilots landing successfully at the Lagos and Kano airports respectively.
“The Emirates airline was the first to carry out the approach test on Global Navigation Satellite System (GNSS) in Lagos while the KLM recorded same in Kano.
“With the success recorded in our quest for moving from terrestrial to a satellite-based air navigation system, Nigeria has joined the league of big countries that are already operating the ICAO-endorsed air navigation programme,’’ he said.
ICAO is the International Civil Aviation Organisation.
Udoh said that the Nnamdi Azikiwe International Airport, Abuja and the Port Harcourt International Airport were among the four airports in the country listed for the pilot test.
“To operate on GNSS, aircraft are expected to be equipped with the prescribed gadgets on board for easy link with the satellite for seamless navigation and communication to designated airports.
“The pilots of the two foreign airlines, while making approach to landing at these airports, had little or no contact with the air traffic controllers except that they were under close watch and monitoring on the radar.
The NAMA boss said that the PBN was cost effective, explaining that it required less fuel during aircraft takeoff and landing.
He added that the system reduced carbon dioxide emission and air traffic controllers’ workload.
Udoh said that NAMA begun the transformation with the completion of the N360 million World Geodetic Survey (WGS-84) of Nigeria’s 22 airports and the procedural design of the country’s four major airports in 2010.
He said that 60 workers in the aviation industry were undergoing training on the satellite-based air navigation system.
The NAMA boss said that the trainees included air traffic controllers, pilots and the personnel of the Nigerian Civil Aviation Authority, Nigerian Air Force, Nigerian College of Aviation Technology and the crew of the presidential fleet.
“They are being trained by a PBN expert, Mr Ed Hajek, from the International Air Transport Association, Montreal, Canada,’’ he said.
He said that NAMA would train about 250 air traffic controllers on the PBN system.
