Malaysiakini - Transport Ministry explains challenge to S'pore over Seletar Airport (extracts):
North is Johor, Malaysia
The Transport Ministry has produced a video explaining why it is opposing the new aircraft landing protocols at Singapore's Seletar Airport.
The issue stems from Seletar Airport's bid to implement an Instrument Landing System (ILS), which will enable planes to land safely even in poor visibility.
However, the flight path Singapore wants to use for the ILS is over Pasir Gudang, Johor.
As the airport is just 2km across the Johor Straits from Pasir Gudang, the ministry explained that this would negatively impact development in Pasir Gudang.
This is because the ILS requires a height buffer, which at 6km away from Seletar would be 145 metres.
This, in turn, means that development in Pasir Gudang, as well as activities at the local port, would be significantly hampered.
Singapore plans to implement the ILS at Seletar Airport on Jan 3 next year.
Transport Minister Anthony Loke said this move went against the principles of national sovereignty, as provided for by the Convention of International Civil Aviation.
Anthony Loke is correct, that to ensure safety altitude (height) allowance for aircraft on the ILS system flying over Johor into Seletar's Runway 21, the Johor area over which the aircraft using the ILS system flies, must be clear of high buildings and other altitude 'obstacles' like high radio masts or even tall cranes (including those on ships sailing near the area).
Actually Loke is being nice to the Sings because Malaysia could ignore the safety requirements of the Seletar Runway 21 ILS and erect whatever we want on our land.
Of course it's unconscionable for Malaysia to do so without advising Sing. But the ball lies in Sings' hands as to whether they want to have an ILS without safety requirements.
If they are going to remain hard-headed, Malaysia should just inform ICAO and advertise clearly in international aviation gazettes and publications that Malaysia is not bound to ensure the safety protection of a foreign ILS approach over Malaysian soil.
The Transport Ministry has also promoted a video to highlight the dangers of the ILS approach if Malaysia were to build high buildings or other erections - see below:
