Singapore Appraoch & Departures Airspace

Singapore being something like 10nm in diameter, who controls the airspace around Changi, given that Singapore is surrounded by sovereign territory on all sides. Does Changi have control of other nations airspace.

Am I right to guess that Singapore control might be a multi national joint venture. Say if you are on approach to Batam Island (Indonesia), are you talking to an Indo controller that's in the Singapore Facility.

Just curious how it works.

Nomorecatering,
What I can tell you is that whatever the detailed arrangements with Indonesia, they work extraordinarily well.
With Malaysia, mostly (but not always) the same.
Tootle pip!!

Yes it runs smoothly with Indo. Even if you’re heading into SIN from the east and are outside VHF and using HF.

Singapore controls the airspace above a certain altitude over parts of southern Malaysia and the nearby Indonesian islands.

No, you’d be talking to a Singaporean controller initially and would then be handed over to Tanjung Pinang approach (Indonesian) closer to Batam.

I used to be a flight instructor based in Batam so I know this area quite well. Batam tower controls the terminal area within a 10 mile radius of Batam airport below 3000 ft. Above 3000 ft, the airspace is controlled by Singapore Radar. South of Batam below 3000 ft, you're controlled by Tanjung Pinang approach (Indonesian FIR). Above 3000 ft, you're in Singapore controlled airspace.

Tanjung Pinang approach radar is quite ancient having visited their radar facilities a few years ago and they sometimes don't pick up targets below 3000 ft, where as Singapore's radar does. On cross country flights to the west of Batam, Singapore radar would see us on their screens but after getting transferred to Tanjung Pinang, we often get 'not identified' on their radar.

There is talk that Indonesia wants to control all of the area south of Batam above 3000 ft (and charge the users for transiting their airspace) in the next few years.

Indonesian Law 1/2009

Interesting reading for those involved in this discussion. Take a look at Article 458 and think of the consequences for "Area A and Area B" and the efficient or even any operation at an airport with effectively north south runways pointing at those blocks of airspace if the ATM for approaches to that airport were not managed by the state operating the airport.

just saying...

MJG
Worked in DGCA Indonesia for 3 years when the topic of resuming both areas was often very energetically discussed.

The english translation of Article 458 of Indonesian Law No. 1/2009 reads:

The airspace of the Republic of Indonesia, whose navigation services are delegated to other countries under an agreement shall be evaluated and serviced by the service provider of the air navigation service no later than 15 (fifteen) years after the Act becomes effective.
In other words, Indonesian law calls for all Indonesian airspace to be serviced by Indonesia by 2024.

ICAO has a plan for this kind of situation and there is a good explanation of what is called "seamless" airspace here <https://www.canso.org/sites/default/files/CANSO%20Guide%20to%20Seamless%20Airspace.pdf>.

The Singapore area is not the only problem, Europe is probably the worst, but on the other hand is the area trying to do something about what are called "functional airspace blocks"
