The Civil Aviation
Authority of the Philippines (CAAP) has issued a notice-to-airmen
(NOTAM), saying the Manila radar would be out of service for maintenance
from October 21 to 26.
There would be a continuous outage of the radar service from 1 p.m. to 7 p.m. on October 24, the NOTAM said.
During
this period, all landing and takeoff procedures would be done through
“conventional” means, using the celestial navigation called STAR, and
Standard Instrument Departure.
To limit congestion, air traffic
controllers would limit the number of aircraft under its control to 11
arrivals and 11 departures per hour.
“International flight schedules will be the first priority for the arrival and departure sequence,” the Caap said.
To
give more airspace within the Ninoy Aquino International Airport
Aerodrome, the Caap said general-aviation flights will not be allowed.
“Departure
flights will be subject to Air Traffic Flow Management release, and
departure,” the Caap added. Flights will be advised of their estimated
departure clearance time while waiting for clearance on the ground.
To
meet the flight-separation requirement, air traffic controllers said
five to seven minutes of separation must be applied between flights
while in the holding patterns, since possible complications may arise
during bad weather condition, unexpected flight delays, or during
emergencies.
The Caap told the Airline Operators Council (AOC)
that it would be prudent to advise their head offices to assign
sufficient extra fuel for Manila-bound flights affected by the radar
outage schedule to avoid flight diversions.
The chairman of the
AOC, Herr Obusan, the local manager of Japan Airlines (JAL), said he had
recommended to Jal to add at least one hour extra hour of fuel when
leaving Narita, Osaka, for the Ninoy Aquino International Airport.
