Flaps 1 versus flaps 5 Taokeoff 737
Guys,
whats the main difference after the lift up. do I have a better climb performance with flaps 1 or flaps 5? And whats the purpose of improved climb?
Why do many airlines use Improved climb as std? What are the pros and cons?

F5 gets you airborne quicker, but with a worse climb angle. If you look at the Take-Off Performance tables for runways, very often the runway is Obstacle Clearance limited, and it is this that limits take-off weight. So the F5 take-off is more limited. With F1, the take-off run is slightly longer, but once airborne, the climb is steeper, so the take-off weight is usually much higher. It can make quite a difference. The improved climb table gives you higher weight, and I think more reduced power take-off saving engine wear.
