I am talking about development flights. Not user flights. All developments flights would be carried out in controlled environment along with introductory flights. Only during user trial it would go through flights trials under uncontrolled environment. Demands would come from user and trials of that would happen accordingly.No, it will depends on the demand. If it is required to be operational under certain extent of bad weathers, such as rain, snow, wind, then you have to carry some tests under such kind of weather conditions. That is why generally, any new missile can only be declared a success after 10-15 tests. But for the beginning, the whole system must pass the test in ideal condition first.
