After having it tested last weekend, the Manila International Airport Authority expects the new instrument landing system (ILS) of the Ninoy Aquino International Airport to be fully operational this weekend. MIAA General Manager Jose Angel Honrado hinted in a radio interview Wednesday the calibrated ILS may be operational in "one to two days." “Yung ILS natin ay tapos na ang flight check, so certification ang kailangan natin. Siguro one to two more days operational na ito, magkakaroon ng advice sa airlines na operational ang instrument landing system," Honrado said in an interview on dzRH radio. (Flight checks for our ILS have been completed, so all we need is a certification. In one to two more days, it will be operational and we will advise airlines accordingly). On the other hand, he said it is now up to the Civil Aviation Authority of the Philippines (CAAP) to inspect other navigational instruments at the NAIA. Last July, the NAIA was forced to divert several flights after haze covered the area around the airport. The poor visibility last July 3, and the lack of some electronic instruments, forced the NAIA to divert at least 22 flights – four international and 18 domestic – to the Diosdado Macapagal International Airport in Clark Field Pampanga, Mactan International Airport in Cebu and to Iloilo.
