The indicator ( A) according to the invention comprises means ( ) for determining first and second target values respectively of a variable and of its derivative with respect to time, and display means ( ) which depict on a display screen ( ) a means of indication ( ) of the first target value, which is arranged in such a way as to indicate this first target value on a graduated scale ( ), and a means of indication ( B) of the second target value which is associated at least with an indicator element ( ) indicating said derivative so that, when the latter points toward said means of indication ( B), said variable of the aircraft becomes equal to and remains equal to said first target value and said derivative is equal to said second target value.

Indicator of a variable for aircraft

The present invention relates to an indicator for monitoring the path of an aircraft in a horizontal plane, comprising:

Indicator for monitoring the path of an aircraft in a horizontal plane

The present invention concerns a device for indicating the position of an aircraft (H) notably a helicopter (H) with respect to a beam (F). In accordance with the invention, said indicator includes fixed first means (6) indicating the position of said aircraft (H), movable second means (7) indicating the position of the beam (F) in a predefined direction with respect to said aircraft (H), and third means (8) indicating which way to steer the aircraft (H) in the predefined direction to capture the beam (F) to said third means (8) being activated only when the aircraft (H) has crossed the beam (F) completely and is outside it.

Aircraft position indicator device

A horizontal speed indicator for a rotary-wing aircraft includes first and second sensors for determining, respectively, the heading and the horizontal speed of the aircraft. The indicator processes the signals delivered by the first and second sensors, and displays the processed signals on a screen, which includes a compass rose which can rotate when the aircraft alters its heading, and a scale which represents the horizontal speed of the aircraft. The scale includes cross wires and concentric circles, and is capable of moving with respect to the compass rose.
