Hi there, I agree with Bigedmustafa, it depends on the quality of the wind. If you have wind that is constantly blowing in one direction, flying would be considerably easy (of course, it has to be an average wind), but if you have winds that are blowing in all directions, flying could be a headacke. I am not an expert but I have been flying for several months in harsh conditions and I have been able to detect the good and the bad winds. Here in Colombia we have hundreds of clubs, and mine is at an altitude of 4800 feet above sea level. It is pretty high, considering that all planes and engines are tested at sea level. My club has pretty nice mountains surrounding it, that are, of course, several miles away and it won´t be dangerous to crash into them. But there is one factor that could be difficult to manage: The wind. That is because of the mountains and the change of temperatures in the air. As I said before, I am not an expert, so I want to know how can I measure the wind speed, the turbulence, in order to see when I can fly. I´ve always trusted in my eye, but I want to have an instrument that tells me exactly when can I fly and when I can´t fly. I´ll appreciate any help. Thanks.
