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.

A combined altitude and height-above-ground indicator for an aircraft enables the altitude and the height of an aircraft to be displayed simultaneously. The combined indicator includes a first sensor and a second sensor which respectively sense altitude and height above ground, means for processing the information supplied by the first and second sensors, and means for displaying the sensed altitude and height-above-ground information by superimposing the altitude and height-above-ground information on the same scale against a pointer. The scale includes a transparent first part which represents a pressure-altitude display, and a second part which is a mask positioned under the first part so that it masks the background of the indicator for altitude levels which are below the measured height above ground. An advantage of the indicator is the ability to incorporate into an altimetric indicator adjusted by a pilot a device capable of warning the pilot of an abnormal situation such as unintentional closeness to the ground as a result of poor altimeter adjustment.

A power margin indicator for a rotary-wing aircraft, intended to give information on the power margin available on at least one engine and one gearbox of the aircraft. The indicator includes: (a) input unit (,) for the various control parameters of the engine and of the gearbox, (b) calculation device (,) connected to the input unit (,) which, on the basis of the parameters, formulate the power margin, expressed as a collective-pitch value, and (c) display units (,) showing, on a display screen (,), the power margins represented on a scale (,) which is graduated in collective-pitch equivalents, capable of moving past a pitch index (,) in a window (,) of the screen (,).
