This gives Helikites various advantages over traditional aerostats. Traditional aerostats need to utilize relatively low-lift helium gas to combat high winds, which means they need to have a lot of gas to cope and so are very large, unwieldy and expensive. Helikites exploit wind lift so they only need to be a fraction of the size of traditional aerostats in order to operate in high winds. Helikites fly many times higher altitude than traditional aerostats of the same size. Being smaller, with fewer construction seams, means Helikites have minimal problems with gas leakage compared to traditional aerostats, so Helikites use far less helium.
