What is the triangle on the a320?

If there is a problem on-board and the crew is unsure about the condition of the aircraft, the triangle indicates what window should be used to inspect flaps, slats or engines or look out for icing. This saves important time in case of an emergency, as the crew doesn't has to search the right window to look out.

Pilots move the yoke so much when landing because they are constantly making small adjustments to ensure a safe and smooth touchdown. The pilot is monitoring the aircraft's speed, altitude, attitude, and other factors in order to make sure that all of these variables remain within acceptable limits.

It's called the PTU, or Power Transfer Unit. It's basically an extra hydraulic pump that assists the system as necessary, and also does a self-test during engine start. But, it's very loud and people don't like strange, loud noises on airplanes, so I understand how it can be disconcerting!

In the case of flight 1549, the pilots of the Airbus A320 made a decision to land in the Hudson River after apparently losing power in both engines. In aviation terminology, that type of landing is referred to as ditching, and as far as jetliners go it remains a fairly rare event.
