thanks, @PapaTony ....my Dad was an airline captain, so I do know that a bit!!.......you and I need to hang out over a beer some day!!......
the runways at SIN are 2L/20R, 2C/20C, and 2R/20L.......the picture above (best I could find for this purpose) is from a 2015 article in The Straits Times and, based on a recent Google Earth picture, the new runway (2R/20L) is finished, but the taxiway connections are still being built.....and Terminal 4 is done.......Terminal 5 not started....
still wondering what the normal/usual approach is at 8AM!....
