• an indicating device arranged on the door panel, the indicating device comprising:
• at least one of an optical signal device for emitting an optical signal or an acoustic signal device for emitting an acoustic signal,
• a status signal input for receiving a predefined status signal indicative of the activation status of the emergency slide, wherein the status signal has a first signal state, assigned to an activated state of the emergency slide, and a second signal state, assigned to a deactivated state of the emergency slide, and
• a control device, connected to the optical signal device and the acoustic signal device, respectively, and to the status signal input and which is configured to operate the optical signal device and the acoustic signal device, respectively, as a function of the status signal received via the status signal input, in order to indicate the signal state of the status signal, wherein
• the indicating device is configured as a continuous, compact unit, which is configured to be arranged on a door of an aircraft,
• the indicating device further comprises an inclination angle measurement device connected to the control device and configured to determine the inclination angle of the indicating device about a predetermined axis and emit an inclination angle signal output, and
• the control device is further configured to determine, on the basis of the inclination angle determined by the inclination angle measurement device, whether a predetermined inclination angle about the predetermined axis has been exceeded for a predetermined period of time, and to only emit a predetermined output signal via the inclination angle signal output if the predetermined inclination angle has been exceeded for the predetermined time period,
• an emergency slide, having a retracted state, from which the emergency slide can be selectively extended to a first extended state with a first length and to a second extended state with a second length which is different from the first length,
• an emergency slide actuation device, adapted to trigger the extension when the door panel is moved from the closed position towards the opened position and the emergency slide is in the activated state, and which comprises
• an activation element, movable to a first activation state, in which the emergency slide is in the activated state, and to a second activation state, in which the emergency slide is in the deactivated state,
• a status signal output, at which the status signal is emitted and which is connected to the status signal input, and
• an inclination angle signal input, connected to the inclination angle signal output,
• wherein the emergency slide actuation device is further adapted such that, when triggering, it controls the extension of the emergency slide in such a way that, when the predetermined output signal is not received at the inclination angle signal input, the emergency slide is extended to the first extended state, and is extended to the second extended state when the predetermined output signal is received at the inclination angle signal input.
