Denk goed na voordat je je aan glijvluchten met een kite waagt: In de VS is een 50-jarige met, naar verluid, 2 jaar ervaring bij de afzet van de glijvlucht in een oncontroleerbare rotatie terecht gekomen en zo niet meer wist waar hij de kite heen moest sturen.


Based upon the limited information available it has been concluded that the man may have caught a ski edge as he left the surface putting himself into rotation. He may have panicked and pulled excessively hard on one side of the bar driving the kite downward, losing his lift and sending himself hard into the surface. Another possible explanation is that once the kiter leaves the surface, his skis will "weather vane" cross to the apparent wind. This can result in more rapid rotation but is thought to not have been the cause in this instance.

Once the kite leaves the vertical and upward momentum of the kiter dissipates they will fall at speed. It is important to maintain lift when gliding well off the ground usually with the kite overhead and largely undisturbed to aid stable flight. The kite was seen to be low and off to the side of the kiter prior to impact. Snowkiters on skis may rotate around the bar to correct for the backward pull of the kite when leaving the surface. This reverses the normal bar response, e.g. pulling right turns the kiter left vs. what may be the more accustomed direction. This bar rotation may have been a source of confusion and rapid loss of kite control.

Some expert kiters have concluded that his judgment was poor in electing to go to the top of the mountain at his ability level. The demands and inherent substantial risks of higher altitude gliding are not to be underestimated although it can be easy to not fully appreciate all the risks. Kiting can seem to be deceptively easy and harmless until something goes seriously wrong. Unconfirmed reported diabetes and indications of low blood sugar might have contributed to this poor judgement. If present, this might have also compromised his ability to effectively respond to the emergency after launch.

The man’s kite, bar, lines and quick releases were examined for proper function. They were found to be properly inflated, correct and working properly. He was wearing a substantial climbing harness in lieu of a weaker kiteboarding harness as is becoming more common among snowkiters.

Naar zeg.
Ik denk dat de expert kiters wel gelijk hebben. 2 jaar ervaring is niet veel om sprongen boven land te maken. Je orrientatie zit dan nog niet ingebakken.

Hangt er ook een beetje van af hoe frequent die ervaring was in 2j.
Ikzelf na 3j weet dat ik zoiets absoluut nog niet zou moeten doen, ik durf bij grote sprongen ook wel nog eens m'n evenwicht te verliezen.
