Patent ID: 7639154

Claim:
A method for regulating a luminosity of at least one indicator light of a monitoring and control equipment for an airplane, when the at least one indicator light is in an illuminated state, the method comprising: receiving an order from a first control for regulating, roughly continuously or with relatively small increments, a luminous intensity of at least one legend or at least one display of the monitoring and control equipment by setting a luminous intensity value (Ilcd) for the at least one legend or at least one display; receiving an order from a second control for switching a luminous intensity of the at least one indicator light of the monitoring and control equipment between at least two modes corresponding to at least two distinct luminous intensity levels for said at least one indicator light, wherein, for at least one of the two modes, a different value is given to a luminance of the at least one indicator light depending on whether the luminous intensity value (Ilcd) setting of the at least one legend or of the at least one display is greater or less than a predetermined threshold value (Ilthreshold).
