Abstract: Managing a payload distribution for a flight includes specifying a flight with a payload distribution to be managed, obtaining, based on a flight timed event, historical payload data to determine a maximum takeoff weight limit for the flight, retrieving, based on the flight timed event, all planned payload values to determine an estimated takeoff weight for the flight, and obtaining, based on the flight timed event, actual payload values to manage the distribution of the payload for the flight.

Abstract: A method of authenticating a first object to at least one further object, especially a vehicle to a key, is disclosed in which information is transmitted unidirectionally between the first object and at least one further object, the computation result is calculated from parts of the transmitted information in the receiving object in each case, the calculated computation result is compared with a computation result transmitted with the information, and only if these match is the sending object viewed as authenticated and the computation result declared invalid for further transmissions.
