In an altitude and vertical speed indicator for aircraft, an altitude indicator includes a graduated scale vertically mobile past a fixed marker and a vertical speed indicator includes a pointer rotatable about the point of intersection of a straight line segment through the fixed marker and a straight line segment through the pointer and pointing towards the mobile scale. The angle defined by the fixed marker and the pointer is representative of the vertical speed value.

Altitude and vertical speed indicator for aircraft

A flight control system for an aircraft, particularly for a helicopter receives a number of items of information, especially the position of flight control members of said aircraft, and sends, depending on these items of information, control inputs to controls of the aircraft. The flight control system includes at least one sensor which measures values representative of the flight of the aircraft and computing means which generate, at least from these measured values and from the positions of flight control members, corrected control inputs which are sent to the controls and which enable control of the lateral speed of the aircraft with respect to the ground, without varying the course of the aircraft.
