To enable intervention personnel to directly enter from the outside the flight deck or cockpit of an aircraft, e.g. in the case of an accident, it is proposed that a window (14) opening from the inside of the cockpit be transformed into an emergency exit accessible from the outside of the aircraft. For this purpose, addition takes place to the existing mechnisms of a handle (50) placed in a recess (52) opening to the outside, as well as manipulating mechanisms. These mechanisms consist of a first linkage acting on the bolts of the window (14) and a second linkage (72) acting by a roller (106) on a cam surface (108) formed on a lever (32) of the window displacement control mechanism.

Emergency exit accessible from the outside for an aircraft cockpit

The leading edge (12) of an aircraft wing is equipped with a kruger nose which includes a rigid flap (18) and a mechanism (26,28,30,40) ensuring the deployment of the flap in an intermediate landing position (P3) and in a take-off position (P2). The disposition of this mechanism is such that, in the landing position (P3), a slot exists between the flap (18) and the leading edge, whereas this slot disappears in the take-off position (P2). The mechanism preferably includes two connection rods (28,30) connecting a control reversing lever (26) and an intermediate reversing lever (40).
