Увидел рекламу курса пилота квадрокоптеров от Skillbox. Если прочитать внимательно, то становится понятно, что этот курс чисто онлайновый, а, значит, дают там теорию и пилотирование в симуляторе.
Я уже давно довольно хорошо летаю в симуляторе, а вот в реальности плохо. По крайней мере, если бы я вышел с таким умением после платного курса, я бы считал этот курс неудачным. Первый раз, когда я вышел "в поле" после симулятора, я едва смог приземлиться, не сломав дрон. Никакой симулятор не даёт 100% похожести на реальный мир, и в симуляторе гораздо проще рисковать.
Пожалуй, со стороны школы нормально было бы запустить платные уроки с инструктором, который физически выезжает с тобой на точки. В идеале, чтобы сама школа построила тренировочную полосу с воротами и рамками, и даже выдавала какое-то оборудование. Но онлайн-курс это полная туфта. Если программированию учат таким же образом, то я примерно понимаю претензии к этим школам.
