Interactive System and Method for Integral Emergency Unlocking of a Locked Cockpit Door on an Airplane
First Claim
1. An interactive system for unlocking a locked cockpit door of an airplane, the interactive system comprising:
- at least one ground station, andat least one data transmission system for transmitting data between a ground station and the airplane, wherein a signal for actuating a door unlock mechanism of the cockpit door can be transmitted from the ground station to the airplane,a door unlock request unit provided in a passenger cabin of the airplane to generate a door unlock request signal;
a signal transmitting unit for the door unlock request signal in the airplane;
at least one image capture unit in at least one of the passenger cabin and a cockpit of the airplane and an image transmitting unit in the airplane for transmitting detected images to the ground station;
a receiving unit for receiving a door unlock signal in the airplane;
an on-board computer in the airplane, which is configured to receive the door unlock signal from the receiving unit and to activate the door unlock mechanism of the cockpit door;
the at least one ground station being connected to at least one receiving station for door unlock request signals and image signals emitted by airplanes, andthe at least one ground station being provided with or connected to at least one transmitting unit for door unlock signals.

Abstract
An interactive system for unlocking a locked airplane cockpit door having at least one ground station and at least one system for transmitting data between the ground station and airplane, including a ground station signal for actuating a door unlock mechanism. The airplane has: a passenger cabin located door unlock request unit to generate a door unlock request signal; a unit to transmit the request signal; at least one image capture unit in the passenger cabin or a cockpit and a unit to transmit images; a unit for receiving a door unlock signal; and an on-board computer, configured to receive the door unlock signal from the receiving unit and activate the door unlock mechanism. The ground station is connected to at least one receiving station for door unlock request and image signals transmitted from airplanes and is provided with or connected to a transmitting unit for door unlock signals.

7. A method for unlocking a locked cockpit door of an airplane with an interactive system, wherein the cockpit door, delineating a cockpit from a passenger cabin, is unlocked on the basis of an unlock signal emitted by a ground station, comprising the following steps:
-
a) receiving, by the system, the input of a personal authentication key, comprising a passphrase and a secret key, into an input device in the passenger cabin by a first crew member of the airplane crew, wherein the authentication key that is input is sent to an on-board computer of the airplane, which is responsible for unlocking the cockpit door, thereby triggering an image transmission command; b) transmitting, by the system, recorded images and/or live images that are being or have been recorded by at least one image capture unit in the passenger cabin and/or in the cockpit of the airplane to a ground station; c) transmitting, by the system, a door unlock request signal and a personal identification code of the first crew member from the passenger cabin to the ground station; d) verifying, by the system, the personal identification code, the transmitted images and flight information data in the ground station for deviations; e) if no deviations are found, generating, by the system, an authenticated door unlock signal using the public key of the first crew member stored in a memory of the ground station and a secret key of the ground station as signatures for the door unlock signal; f) sending, by the system, the signed door unlock signal from the ground station to the airplane and receiving the signed door unlock signal by a receiver of the airplane; g) forwarding, by the system, the signed door unlock signal from the receiver on the airplane end to the on-board computer of the airplane responsible for unlocking the cockpit door; h) verifying, by the system, the signatures of the signed door unlock signal, namely using the secret key of the first crew member with the personal authentication key entered in step a), and using the public key of the ground station stored on board the airplane; i) unlocking and opening the cockpit door, by the system, as long as verification of signatures of the door unlock signal has not revealed any errors. - View Dependent Claims (8, 9, 10)
