The method of operating a helicopter consists in directing the air flow longitudinally along the tail boom (16) of a helicopter (10) towards some deflecting vanes (30,32) of the thruster mechanism of a helicopter (18) which deflect the air-flow laterally towards the opposed lateral sides of the helicopter (10) and towards some openings (50) in the lateral sides of the rear end portion of the tail boom(16) the height dimension of each opening (50) being adjusted such that the geometrical centre of each opening remains substantially static, regardless of the status of adjustmentThe thruster mechanism for a helicopter (18) consists of a longitudinal volume defined between a fore flange (22) and rear flange (34) and partially limited circumferentially between the lower wall portion (26) and the upper wall portion (28) defined by the dimensions of the openings (50) where there are some deflecting vanes (30,32), vanes deflecting the air flow from some lateral openings of the thruster mechanism for helicopter (18) and the height dimension adjustment of each opening is adjusted by some shutters (46, 48)
