Abstract: A system for flight and task management timeline display is disclosed. In embodiments, the timeline display is positioned on an edge of a primary flight display (PFD) or other avionics display, divided lengthwise into time (e.g., absolute time) and space (e.g., relative time and distance) scales. The timeline display expands situational awareness into the temporal dimension by positioning waypoints in the flight path based on the relative time to passage or flyover. The time scale corresponds to an adjustable time range and automatically scrolls lengthwise according to the current time, but can be manually zoomed or scrolled in past and future directions as well. Based on updates from the flight management system (FMS), the space scale displays relative time-distanced events, notifications for reminders and tasks, and waypoints positioned according to the likely times they will be encountered (or, in the case of reminders and tasks, must be fulfilled).

The described method comprises using processing means for executing the step of offsetting the pixel values of increased bit depth with offsets, the offsets depending on a spatial neighbourhood of the pixel to-be-offset. Such local adaptive offsetting of pixel values de-emphasizes high frequencies in the transform domain artificially emphasized by the bit depth increase.

Abstract: The field of the invention is that of onboard terrain anticollision systems for aircraft. Collisions with the terrain while the aircraft is fully controlled have been and still remain one of the main causes of air disasters. Several generations of devices for warning of risk of collision with the terrain have been developed for some thirty years now. The most advanced of these systems comprise means of alarm differing according to the maneuver to be performed by the pilot. It is of course vital that the recommended maneuver best guarantee the safety of the aircraft. The device according to the invention proposes a device comprising the calculation of several different safety surfaces or profiles. Their comparisons with the topographic data of the surrounding terrain make it possible to deduce therefrom the best alarm and the best maneuver to be performed to avoid the collision between the aircraft and the ground.
