Roll the aircraft. Video. Photo. The allowable limit.



Roll the aircraft (from the French.carène- The keel, the underwater part of the ship or from the English.kren-gen- To put the ship on its side) - turn the object (ship, aircraft, foundation, etc.) about its longitudinal axis. The bank is one of the three corners Eylera.

device showing roll ...If we denote the longitudinal axis Y, then corresponds to the angle α ((or precession angle). Roll the plane by turning the steering wheel to the left or right (mostly), with only RUS, a deviation to the right or to the left, if the joystick is similar. The bank carried out aileron or any other parts that perform functions aileron. The calculations assumed a positive roll counter-clockwise. In practice, used the expression "right bank", "left bank".

An important characteristic is the flight angle of heel at which there is no slipping or loss (set) altitude. Calculated by the formula: alfa = arctan (V ^ 2 / g * R), where V - velocity of the aircraft (in m / s), g- acceleration due to gravity (9,81 m / s2), R- turning radius (m).

Turn the airplane upside down - make a turn around the longitudinal axis of the vessel on 180 degrees (capsizing).

Limitation - 67 degrees.

25 - Margin indicator in the flight.

30 - Allowed for when traversing pripyatstvy

In critical situations, pilots are allowed to exceed the maximum angle of heel, with the goal - to save the lives of passengers.
Restrictions exist for each aircraft and its calculated based on the structure, strength, aerodynamics and speed. According to the regulations of the ICAO.
For example, military and acrobatic aircraft the maximum angle of heel is not defined, so for Su-27 Roll can be 90, and in straight flight. Some planes can so quickly change the angle of heel that transhipment will exceed 9g, such cases have been seen, for example, MiG-21.

Therefore, the pilots who flew the MiG-21, there is an expression: "Iron can survive, but man ...
