I recently flew HKT - SIN on Tiger Airways. The weather on approach into Singapore was fine, although there was some surface water on the runway from an earlier storm. At touchdown, I was sat on the right side of the aircraft, and could clearly see the centerline of the runway almost at the wingtip, meaning that we had landed way off to the left. People did look slightly alarmed, particularly on the left side, as we were so close to the edge of the runway. We didn't realign ourselves with the centerline at all, but stayed in the left-side position.
Is this a normal procedure, or just a bad landing? There were three pilots of the flightdeck for a flight of just an hour, so I assume that one of them was being trained? Is it normal to do this with passengers on board?!
Then, as soon as we turned off the runway, our right engine was switched off and we taxied in to the terminal on one. Is this simply a fuel saving measure from Tiger? Or could it be for something else?

A lot of carriers do single-engine taxi (on a twin) and twin-engine taxi (on a quad) as a fuel saving measure. You can easily burn 600-1100kg of fuel just in taxiing.

Quoting Shamrock321 (Reply 2): I recently flew on A320 and we did a single engine taxi, I noticed alot more nice from what I belive was the hydraulic pumps than noraml, quite alot actually almost annoying, is this normal?
With only one engine running you would have only one hydraulic system pressurized. To insure you have power to all required systems, there is a unit called the "power transfer unit". It does just what its name says, it transfers the power (not the fluid) from one hydraulic system to the other. The noise it makes sounds something like a grunting mechanical pig!
