Method for measuring touch distance in display system for e.g. navigation display, in cockpit of aircraft, involves measuring distance between two points according to predetermined scale, and displaying measured distance in cartridge

摘要

The method involves displaying a map or temporal representation of a flight plan, and allowing a user to perform two simultaneous touches during a predetermined time in two points (P1, P2) of a tactile surface corresponding to a distance to measure, where the two points are connected graphically by a segment (S). A distance between the two points is measured according to a predetermined scale, and the measured distance is displayed in a cartridge (C). One or more parameters related to the distance are calculated and displayed in the cartridge.
