- a fuselage (2);
a first and a second lateral side (11a and 11b) opposite to each other;
a first emergency exit (9a) defined by said first side (11a);
a second emergency exit (9b) defined by said second side (11b); and
at least one said display device (8a, 8b) for displaying the attitude of said aircraft (1) with respect to a fixed direction (V) in space;
characterized in that it comprises;
a first element (15), which can be fastened to said aircraft (1); and
a second element (16), which is free to move with respect to the first element (15), following a change in position of said first element (15) with respect to said fixed direction (V);
said second element (16) in turn comprising;
a mass (14), which is designed to return said second element (16) to the same stable position with respect to said fixed direction (V), when said first element (15) changes, in use, its position with respect to said fixed direction (V); and
a visual indication (18), which is representative of the position of said fixed direction (V), as the position of said first element changes (15);
in the event of said aircraft (1) ditching with said first side (11a) positioned below or resting on the waterline (13), said second emergency exit (9b) being usable and positioned at a higher level than said first emergency exit (9a), which is unusable;
