An apparatus for displaying state and transition information in a system. A sensor and display system is disclosed for displaying aircraft landing gear status. The system utilizes two light emitting diodes (LEDs) for each landing gear leg to display the current position of each gear leg. One yellow LED indicates gear UP and the second green LED shows gear DOWN position. When the control switch is moved to change the position of the gear, the indicator light which had been lit is extinguished, and the indicator for the desired position begins to flash, indicating gear movement. The indicator will continue to flash until the gear leg has reached the limit of travel, at which time the indicator stops flashing and glows steadily. Each gear leg indicator operates independently of the others, so that proper position of each gear leg can be confirmed and any malfunction can immediately be identified.
An aircraft indicator system for displaying a fully retracted state, a retraction transition state, a fully extended state, and an extension transition state of landing gear having a plurality of legs comprising:
