Disclosed is a method and device, which provide an enhanced ability to monitor the navigation of an aircraft during a phase of flight in which the aircraft is close to the ground in which the aircraft uses positional information supplied by a satellite positioning system for the navigation. A display screen is used to display a first characteristic sign representing a selected setpoint value for a height parameter of the aircraft. The display screen also displays a second characteristic sign representing a current auxiliary value expressed in the form of an achievable height parameter. An alert is emitted when the second characteristic sign is determined to be within a predetermined height value of the first characteristic sign, and the alert is shown in visual format on the display screen. An alarm is also emitted following a predetermined time after the alert is emitted, if the setpoint value is not replaced by a new setpoint value.

The device (1) comprises means (3) for determining a descent axis making it possible to fly from a safe altitude to a decision height, said descent axis being secured relative to the ground being flown over, and a guidance system (5) to assist in the guiding of the aircraft along said descent axis in a descent phase.

The invention relates to a method for monitoring a person carrying a cellular telephone through a communication network wherein: An expected path for the monitored person is determined by identifying a sequence of successive places or checkpoints, and A real path followed by the monitored person is detected and compared with the expected path, both in space and in sequence, so that An alert is sent to at least one individual, called alertee, through the communication network when the real path differs from the expected path in place, sequence or in both place and sequence. The invention also relates to a cellular telephone and a server implementing such method.

The invention relates to a method and a device for assisting the flying of an aircraft, said method and device being used to determine an approach path and comprising a guidance system for helping to guide the aircraft along this approach path. The inventive method and device define a main approach path (AI) and a corrected approach path that has an extra vertical margin (ΔH) related to the ground over which the craft is flying as compared with a main approach path representing a category 1 precision approach. Said guiding system guides the aircraft following the corrected approach path.

The flight control indicator (1) comprises a central unit (3) able to determine any change of trajectory corresponding to a vertical change which represents a change of vertical segment or a lateral change which represents a change of lateral branch, and means of display (5) which are able to present, on a viewing screen (7), a first means of indication indicating a next vertical change and a second means of indication indicating a next lateral change, and which are formed in such a way as to present at least one of said first and second means of indication, namely the one indicating the change of trajectory which is closest, from the current position of the aircraft.
