Какие реальные показатели прочности Суперджета?
737 максимальный взлетный вес 44 тонны, макс посадочный 40 тонн. В крупных моделях (150+ пассажиров) разница побольше, около 10-15 тонн. Однако из руководства "Overweight landings up to maximum takeoff weight may be safely accomplished by using normal landing procedures and techniques." То есть тяжело, но в пределах расчетных параметров прочности и самолет не развалится.
Embraer E190-2 максимальная взлетная 56 тонн, посадочная 50 тонн.
SSJ указан взлетный макс 45 тонн с макс 15 тонн топлива. В салоне было 78 пассажиров, что меньше чем максимальная вместимость человек на 20, минус около 2 тонн. Топлива вряд ли было под завязку, Мурманск не так далеко, примерно 1200 миль против 1850 заявленной дальности машины. Так что топлива было, видимо, около 10 тонн. Стало быть, посадочная масса с 78 пассажирами и 10 тоннами топлива вполне должна быть в пределах расчетных параметров.
Комментарий пилота Боингов
Actually, most, if not all, modern commercial aircraft can land with full tanks and at full max takeoff weight.
All that is required is an "overweight landing check" where wheels, brakes and landing gear are checked for any damage and the flight data recorder is checked for the g-force generated at touchdown. It is this data combined with the aircraft weight that determines the extensiveness of the check. In general if touchdown is at less than 300 ft/min (which most would consider a pretty firm landing), it is just a cursory check.
An immediate overweight landing would be desired if, for example, there was a fire on board.
Еще комментарий пилота 767, посадившего 767 с одним двигателем и полными баками и полным салоном пассажиров.
"You can. I did it in a 767 with full fuel and full passengers, on an evening flight. Shortly after rotation off runway 2*L we experienced a right engine failure. Once airborne, and very slowly climbing away from the runway, we declared an emergency, then executed the emergency engine failure checklist and then complied with all the procedures set forth in our training. Once at a safe single engine altitude we thoroughly discussed the pros and cons of an over weight landing for runway 2*R. Once we were completely satisfied an over weight landing could be accomplished safely, we began to prepare to accomplish a single engine, over weight landing. Within 10 minutes of take off, we safely landed with out further incident or damage to the aircraft.

Most of todays modern aircraft are not capable of dumping fuel but are certified by the FAA and aircraft manufacturer to accomplish these over weight landings."
