Abstract
A device for indicating an activation status of an aircraft emergency slide. The indicating device comprises an optical and/or acoustic signal emitting device, a status signal input, with a first input signal for an emergency slide activated state, and a second signal for a deactivated state, and a control, connected to the signal device, and to the status signal input, and configured to operate the signal device as a function of the status signal received, to indicate the status signal state. The indicating device comprises an inclination angle measurement device connected to the control for determining the inclination angle about a predetermined axis and provide an inclination angle signal output. The control determines, based on the determined inclination angle, whether a predetermined inclination angle has been exceeded for a predetermined time period and outputs, via the inclination angle signal output, a predetermined output signal only when this has occurred.
