Abstract
An indicating device for indicating a non-authorized opening of an aircraft door comprising a sensor for detecting a distance from the sensor to an object, a signaling device, a reset device coupled to the signaling device allowing the signaling device to be set into a first state following a reset operation, an enabling device, providing as an output signal, selectively, a disable signal and an enable signal, and a control device connected to the sensor, the signaling device and the enabling device. On receiving the disable signal, the control device changes into a first operating mode and on receiving the enable signal it changes into a second operating mode in which, based upon the signal received from sensor, it detects a distance change between the sensor and the object, and, on detecting a change, sets the signaling device into a second state until the reset operation is completed.
