|LANDING AIDS IN 14 AIRPORTS CALIBRATED|
Air navigation network across fourteen airports in Nigeria got a boost lately following the positive status of majority of the landing aids hitherto said to be obsolete or unserviceable.
With the latest development, pilots flying into or out of these airports, have been experiencing less stress.
The positive status of navigational aids was unraveled following the report of the Dakar based French agency, ASECNA which carried out the calibration of the landing aids on behalf of the Nigerian Airspace Management Agency (NAMA) in July, 2008.
For example, the report indicated that the four transmitters of the Instrument Landing Systems (ILS) CAT 2 on runways 18R (LLZ) and 18L (GS) at the busy Murtala Mohammed International Airport passed the calibration tests.
Specifically, it said the ILS 18R had its two localizer transmitters operating correctly. The monitor operates correctly while it is also usable without any restriction.
As regards the Nnamdi Azikiwe International Airport, Abuja, the calibration carried out on 19, July, 2008 indicated that the ILS Cat-2 on runway 04 (LLZ) scaled the test with its two localizer transmitters operating correctly. The monitors operate correctly while the ILS/DME usable without any restriction. The Glide, it noted needed to be ground check for ILS on runway 04 (GS).
The ILS Cat 2 on runway 06 (LLZ) at the Aminu Kano International Airport also scaled the calibration tests and is said to be usable without restriction, while the ILS Cat 2 on runway 06 (GS) had its two Glide/DME Transmitters operates correctly after sector adjustments. The two ILS/DME also operates correctly within ICAO tolerances.
The Precision Approach Indicators (PAPI) 06 and 24 at the Airport; the report however noted needed a complete ground adjustment before the next flight check in another six months.
Other airports that scaled the ILS/DME calibration include Ibadan, Osubi,Enugu, Yola, Kaduna, Calabar, Owerri, Minna, Sokoto, Ilorin and Jos.
