THE ABILITY TO LOFT OR LIFT VERTICALLY HAS NOT BEEN DESIGNED OUT OF MODERN KITESModern kites have the ability to adjust their AOA something which older C kite did only minimally, but AOA adjustment range is limited even on modern kites and when you reach it (and you pull on the bar to gain control or stabilise yourself, OOOOF up you go).
There are people who have very little experience with windsports and kites, who think their modern kite has an infinite safe wind range and that "depowering" the kite more and more will make the kite useable in winds that are basically too much for that size kite.
The biggest error this industry is continuing to make is calling the trim system, the "Power and Depower" system. This is the main cause of the common error in beginners thinking that their kites have an almost infinite wind range (certainly way more than in reality).
Each kite design, and some have more and some have less, has a finite AOA adjustment range. You can experience this and prove it to yourself too, by shortening your front line to the max with your lines tied off to a tree or something. If you can shorten your front lines to the point where the rear lines are so loose that when the bar is angled to simulate a turn or steering input, that the rear lines remain loose, then thats what will happen when the kite is flown -
YOU WILL HAVE NO ABILITY TO STEER THE KITE.This inability to steer the kite when it is so "depowered" is the No 1 cause of rapid kite dragging, lifting and impacts with solid objects. When a kite has been "depowered" to the point where it cannot be steered, the fact remain that it is still the same size kite, and that its AOA has been adjusted so much that it now flies at its fastest possible speed, and this in turn cause the now unsteerable kite to develop that absolute maximum power that it can develop. So the reality is that "depower" adjustment makes the kite fly faster across the window and this in turn increases the power and lift delivered by the now out of control kite.
BUT, kiters are responsible to read the manufacturers recommended wind range and to not exceed it without understanding that are now putting themselves and others at the risk of serious injury or death.
The "power/depower" system does not change the size of a kite. The "power/depower" system on many kite can be adjusted so much that the kite cannot be steered when max "depower" is applied" this includes many top well known brands!
The "power/depower" is incorrectly and dangerously named, it is a
trim or trimming systemYachts and windsurfers adjust the angle of attack of their sails, and and so do planes and gliders for their wings, etc, none of them use the term "power/depower", they all use the term
