Повнимательнее! Человек не центровку (фокус) спрашивает, а центр тяжести.
Его считать трудно. Чаще просто измеряют балансировкой.
Фокус же считать усреднением, так как описано выше можно, если верхнее и нижнее крылья одинаковые по форме и площади.
Да, именно центровку мне и нужно…
А если полутороплан (Чайка)?
То как считать?
Ну потерпи ты до вечеру 😃 Не помню я так сразу ссылки 😦
