Malaysia shuts down plans for ILS approach at Singapore’s Seletar Airport

Update Jan 8: Latest in the ongoing debacle at WSSL/Seletar: Malaysia have now agreed to cancel the restricted airspace they imposed to the north of the airport, and in return Singapore will suspend the ILS procedures it had planned to implement. These measures will be in place for one month, starting Jan 8, to give both countries time to try to find a more permanent solution to the dispute.

The new ILS approach on RWY 21 at WSSL/Seletar airport was due to take effect on 3rd Jan 2019, but Malaysia have effectively killed it. They claim that the ILS approach –most of which lies within Malaysia’s airspace to the north of the airport– would impose height restrictions around the Pasir Gudang industrial area, and would stunt growth in the area.

Malaysia decided to create a no-fly-zone across an entire chunk of airspace just across the border from Singapore, up to 6000ft. This ultimately would have made RWY 21 ILS approaches at WSSL/Seletar impossible.

Malaysia WMFC/Kuala Lumpur restricted airspace as per Notam A4018/18

Singapore and Malaysia’s foreign ministers met on Jan 8 to discuss this mess; Malaysia agreed to cancel the restricted airspace they imposed, and in return Singapore agreed to suspend the ILS procedures.

The two countries have been locked in a wider ongoing dispute over airspace sovereignty, with Malaysia saying it wants to take back airspace delegated to Singapore under an agreement in 1974. But with the recent turn of events at Seletar, there is now a tangible impact to flight operations.

Discussions between the two countries will continue throughout January, but don’t plan on making use of the ILS approach any time soon.

In other news: The night curfew at Seletar is going ahead as planned. Authorities have now published AIP SUP 86/2018 which confirms that with effect from 1st Jan 2019, the airport will be closed to all flights (except medevac and emergency diverts) nightly from 22-07 local time.

PBCS is coming to Singapore

It’s not only the North Atlantic that will be seeing PBCS being implemented on March 29th – on that same date, the weird acronym is coming to Singapore too!

However, the requirements for Singapore airspace are slightly different to that for crossing the NAT.

The short of it – compliant aircraft will be allowed a reduced separation of 50NM (or 10 minutes in trail) on certain airways: L642, M635, M767, M771, M774 and N884. For everyone else, it’ll be 80NM (or 20 minutes in trail). For Singapore, ‘compliant aircraft’ basically means anything with RNP10, CPDLC and ADS-C capable of the RCP240 / RSP180 performance requirement.

You’ll still need to obtain some kind of operator approval from your State of Registry. As we mentioned in our article on PBCS on the NAT – the best way to do that will probably be to submit an AFM Statement of Compliance for PBCS, showing exactly what data link communication systems you aircraft has, along with the selected performance.

For Singapore, if you want to operate on those airways at the reduced separation, here’s what you’ll need to remember to include in your ATC FPL:

In 10a:

In 10b:

In Item 18:
Make sure you include SUR/RSP180 to show you’re capable of the RSP180 performance requirement.
