1. A weighing system for detecting total weight, including optional external loads, and monitoring of center of gravity of a helicopter, comprising:
- a fuselage of the helicopter,a landing gear, mounted to the fuselage by flanges,weighing cells integrated into said flanges,a control unit for calculations of the center of gravity and total weight of the helicopter, andconnection means from said weighing cells to the control unit for transfer of weights detected by said weighing cells;
wherein each of said flanges has two fork type projections separated from and facing each other; and
wherein attachment means for an external lifting gear are provided at the landing gear for any external loads.

Abstract
A weighing system for detecting total weight, including optional external loads, and monitoring of center of gravity of a helicopter (2), comprising a fuselage (1), a landing gear (4), mounted to the fuselage (1) by flanges (10-13) and weighing cells (41-44). The weighing cells (41-44) are integral with the flanges (10-13) between the fuselage (1) and the landing gear (4). Attachment means are provided at the landing gear (4) for external loads (39, 40).

16. A weighing system for detecting total weight, including optional external loads, and monitoring of center of gravity of a helicopter, comprising:
-
a series of flanges for mounting a landing gear to a fuselage of the helicopter, wherein each flange is connected to the fuselage using a pair of fork like projections spaced apart and facing one another, each flange having; an annular damping element surrounding a strut of the landing gear, a annular casing surrounding the damping element and having a pair of flattened areas defining a pair of borings, and an integral weighing cell, wherein the flattened areas of the casing mate with an inside surface of the pair of fork like projections and a pair of bolts extend through the boring in the casing and a groove in the fork like projection such that the landing gear is mounted to the fuselage; external lifting gear for external loads, the external lifting gear connected to the struts of the landing gear adjacent to the series of flanges; and a control unit in communication with the weighing cells and configured to calculate a center of gravity and a total weight during flight of the helicopter based on a signal from the weighing cells, the total weight during flight being the sum of a weight detected before take off and a weight detected after take off and when clear of ground.
