Claim Text:
1. A method of displaying a flight parameter of an aircraft, with the aid of a viewing screen including a display element dedicated to the flight parameter, the flight parameter having a corresponding viewable scale, the aircraft being guided by a guidance system according to a guidance mode, the method comprising: monitoring the guidance system to detect a situation in which a guidance setpoint relating to the flight parameter is modified by the guidance system, while the aircraft is guided by the guidance system according to the guidance mode having the guidance setpoint, and the guidance mode holds the guidance setpoint; providing a holding range of the flight parameter for the guidance setpoint, wherein the guidance setpoint is highlighted on the display element dedicated to the flight parameter and displayed on the viewing screen; reducing the viewable scale of the holding range of the flight parameter to a size of the holding range of the flight parameter in comparison to the remainder of the scale outside of the holding range upon detection of the situation; performing a check to verify whether a motion of the aircraft is consistent with the guidance setpoint relating to the flight parameter; displaying the scale having a current value of the flight parameter, when the motion of the aircraft is consistent with the guidance setpoint; and automatically adjusting the size of the scale of the flight parameter by delimiting the holding range in a first direction and a second direction based on the current value of the flight parameter and the guidance setpoint when the motion of the aircraft is inconsistent with the guidance setpoint, the first and second directions being opposite from each other.
