Abstract
A flight control indicator for an aircraft, intended to supply the engine pressure ratio, includes acquisition and processing units (2, 3) which determine the actual value of the engine pressure ratio and a display unit (4) provided with a dial (6) and with a needle (7) whose position on the dial (6) corresponds to the actual value of the engine pressure ratio. Moreover, the acquisition and processing units (2, 3) determine minimum and maximum values for the engine pressure ratio, and the display unit (4) presents on the dial (6) a circular sector (8) which is delimited by two radii (8A, 8B) whose positions correspond respectively to the minimum and maximum values for the engine pressure ratio.
