A method is provided for assisting in rejoining a vertical descent trajectory that an aircraft is assumed to have to follow, using a flight management system FMS embedded onboard the aircraft, and includes the following steps: calculation of a vertical deviation VDEV, in the vertical plane, between the aircraft and the vertical descent trajectory, and comparison between the vertical deviation VDEV and a predetermined deviation threshold SVDEV; when the vertical deviation VDEV reaches the deviation threshold SVDEV, a step during which the activation of an optimized mode for catching up on the vertical descent trajectory is authorized; if the optimized mode for catching up on the vertical descent trajectory is activated, piloting of the aircraft by the flight management system FMS in optimized catch-up mode, that is to say at minimum thrust with a target rejoining speed in level VCRP and a target rejoining speed in downward trajectory, the target rejoining speed in level VCRP being equal to the maximum L/D ratio speed of the aircraft uprated by a first value V1 of between 5 and 15 knots, and the target rejoining speed in downward trajectory VCRD being equal to the maximum operating speed VMO with which the aircraft is allowed to fly downrated by a second value V2 of between 3 and 10 knots, a knot being equal to 0.514 ms−1.

An aircraft piloting assistance method and system including determining at least one flyable slope with which the aircraft is assumed to be able to fly, based on a value of at least one flight parameter including the weight of the aircraft. The step for determining said slope or slopes with which the aircraft is able to fly, called flyable slopes is performed by a computer, and presenting the flyable slope to a decision-maker.

The method of generating a secure flight plan portion in the event of depressurization corresponding to a time-conditioned descent profile that may include a succession of levels, comprises: a step of defining a first point of the flight plan, called non-return point, denoted NRP, and a second point of the flight plan, called EOZ, the two points delimiting a portion of the flight plan plotted above an area identified as “with risks”; a step of defining two radials in the horizontal plane respectively passing through the first and the second points; a step of determining a first flight plan portion comprising the definition of a lateral offset angle from the original flight plan; a step of determining a vertical descent profile; a step of displaying time markers indicating the exhaustion of the oxygen reserve.

The flight management computer discloses and carried onboard an aircraft can be programmed with a newly apparent speed constraint while it ensures the guidance of the aircraft in the course of a landing runway approach. It then takes account of the speed constraint by using it as target speed, when it is greater than an instruction speed which depends on the number of extended flap settings and which corresponds to the addition of a further flap setting. If appropriate, the speed constraint may be bounded below, thus making it possible to remain within the limits of the flight domain of the aircraft in its configuration at the time.

Flight management system for aircraft comprising computation means capable of determining a gain or a loss in terms of flight time remaining to a point of arrival, and in terms of fuel consumption, following the input by an operator of a modification of an initial flight plan using the Direct To function. The computation means are capable of suggesting to the operator a modification of the lateral flight plan that procures an optimum gain. The flight management system also comprises a display interface capable of presenting to the operator the information concerning the gain or the loss in time and/or consumption, and of prompting the operator to accept or refuse the modification.

This attitude indicator comprises a display device (11) with screen (110), producing on a screen background (4, 5), a three-dimensional aircraft silhouette (3), mobile according to the three axes of rotation and viewed from the rear, according to attitude angles which correspond to the attitude angle measurements received by onboard instruments and which are referenced with respect to an aircraft datum having a roll axis perpendicular to the surface of the screen and pitch and yaw axes in the plane of the screen, one, the pitch axis, being horizontal and the other, the yaw axis, vertical. It has the advantage of affording the crew a concrete view of the attitude of the aircraft enabling piloting to be rendered more natural and more intuitive, and hence safety to be improved.
