Method and device for ensuring the safety of a low-altitude flight of an aircraft.The device (1) comprises a recording means (8) corresponding to an operation critical instrument for recording, during a low-altitude flight, one part at least of the lateral trajectory of the flight trajectory situated ahead of the current position of the aircraft, a monitoring means (11) for monitoring, during a low-altitude flight, the availability at least of said lateral trajectory, and a guidance system (3) for taking the aircraft up to a safe altitude, taking into account said part of the trajectory recorded by said recording means (8), when said monitoring means (11) has detected a loss of said lateral trajectory.

The invention claimed is: 1. A method to ensure safety of low-altitude flight of an aircraft being guided along a low-altitude flight trajectory, comprising:(a) determining a lateral trajectory and a vertical trajectory of the low-altitude flight trajectory using a trajectory determining unit;(b) guiding the aircraft along the determined low-altitude flight trajectory using a guidance system which is connected by a link to the trajectory determining unit and which receives a transmission of the low-altitude flight trajectory from the trajectory determining unit via the link;(c) recording at least one part of the lateral trajectory of the flight trajectory situated ahead of a current position of the aircraft along the low-altitude flight trajectory using a recording unit integrated into said guidance system;(d) monitoring the transmission using a monitoring unit to detect a loss of the lateral trajectory caused by an error in the transmission; and(e) guiding the aircraft up to a safe altitude, taking into account said at least one part of the lateral trajectory recorded by said recording unit, in response to, in step (d), detecting the loss of the lateral trajectory, wherein:the aircraft is guided automatically in order to be taken up to said safe altitude.
