- checking conditions for the emergency landing of said vehicle;
detecting a maximum speed or an impact speed (VMax) of said vehicle; and
opening said opening valve after detection of an activation speed (VAtt) of the vehicle to deflate said at least one airbag;
whereinsaid vehicle comprises at least one airbags, andsaid opening step further comprises the following sub-steps;

Abstract
A method for emergency landing of a vehicle, such as a helicopter or like, is described. The vehicle has at least one airbag provided with a respective opening valve for allowing the outflow of the gas therein contained. The airbag is suitable to cushion the impact of the vehicle with ground, and is inflated for an emergency landing. The method checks the conditions for the emergency landing of the vehicle, detects the maximum or impact speed of the vehicle, and opens the opening valve after the detection of an activation speed of the vehicle, so as to deflate the airbag. A system for controlling airbags of a vehicle, such as a helicopter or like, is also described.
