Leaders of the Civil Aviation Authority of Singapore (CAAS) have said that they were "determined to entrench Singapore as an aviation powerhouse regionally and globally”.

CAAS’s surplus for the year ended March 31, 2013 rose 15 percent year-on-year to 131.15 million SGD, boosted by higher income from air navigation service charges, aviation levy and ground rent.

According to the CAAS, air navigation service charges - payable by the airport licensees of Changi Airport and Seletar Airport for services provided to air traffic - rose from101.85 million SGD in the previous year to 118.75 million SGD last financial year.

Meanwhile, aviation levy surged from 98.35 million SGD to 109.15 million SGD, and ground rent from 72.55 million SGD to 75.35 million SGD.

In 2012, Changi Airport catered to a record 51.2 million passengers, up from 46.5 million a year earlier. However, cargo carried slipped from 1.87 million tonnes previously to 1.83 million tonnes last year.

In August, the CAAS announced that Changi's Terminal 5, due to open in the mid-2020s, will be built on a 1,080 ha plot of land, a site which is separate from the other terminals. Observers believe that the new terminal will most likely be the airport’s biggest one that will be capable of handling between 30 and 50 million passengers a year.

Construction of Terminal 4, with a planned capacity of 16 million passenger movements a year, will begin this year and is slated to be completed in 2017.-VNA
