I went to T3 today. The skyroof is fantastic. But T3 has some flaws though. As it is mentioned before, the arrival hall and B1's celling is a little too low.
Secondly, the viewing mall disapoints me greatly. I was expecting a fantastic view of runway 02L. But several faults spoils the great location of the touchdown zone of Runway 02L.
Let me name a few faults: The distance between the tarmac/apron and your standing position is too far. It's kinda like T2's style. I can live with this fault though.
But what i cannot accept is the obstruction on the glass. Sunshades placed outside are blocking the view of the runway. To have a clear view of the runway, you would have to bend down to see them clearly. With this obstruction, nobody would have a clearview of planes. But instead, we would see a blurred image of planes which totaly defeats the purpose of having a viewing mall!
I doubt the airport management would do anything to improve the design. I have been wondering why not build an open air viewing mall. It's the best option. I would say, T3's viewing mall is the worst of the 3 terminals. Anybody agrees?
Here's a pic to explain the obstructions (I am already standing as close as possible to the edge) So this is the distance you would be expecting.
Overall, T3 is a fantastic place, save for its viewing mall faults.
