Back to ba­sics for land­ings at air­port as nav­i­ga­tion aid off for next 3 weeks

Sys­tem Will Be Shut To En­able Up­grade: ATC

The Times of India (Mumbai edition) - - TIMES CITY -

Mum­bai: The nav­i­ga­tion aid used by pi­lots to land at the city air­port is be­ing up­graded and will not be avail­able for the next three weeks.

Dur­ing this time, pi­lots op­er­at­ing into the air­port will have only ba­sic nav­i­ga­tion aids to bank on.

The In­stru­ment Land­ing Sys­tem (ILS) of main run­way 27 be­came un­avail­able from 11 am on Thurs­day, May 17, to 11 am on June 5, said a no­tice is­sued by the air traf­fic con­trol (ATC) at the air­port.

“New equip­ment is be­ing in­stalled, after which it will be cal­i­brated be­fore the ILS sig­nals can be switched on,” said a source. its de­scent be­low 1,070 feet.

The air­port main run­way 09/27 lies in the east-west di­rec­tion, per­pen­dic­u­lar to the coast­line. Air­craft that come in to land at the main run­way of the air­port ei­ther fly in from the east or west depend­ing on the di­rec­tion of the run­way in use.

In De­cem­ber last year, a Sin­ga­pore Air­lines pi­lot com­ing to land on run­way 09 at a time when the ILS sig­nals were switched off flew in from the west over the Ara­bian Sea. When pi­lots come in from the west, they spot the Juhu aero­drome run­way first. The pi­lot ini­tially mis­took the Juhu run­way for the air­port run­way.

Yet, that is un­likely to hap­pen in case of ap­proach to run­way 27. The rea­son is that an air­craft per­form­ing an ap­proach to land on run­way 27 comes in from the east and so would en­counter the air­port run­way first.
