Systems and methods for communicating avionic data to a non-avionic device situated outside of the cockpit of an aircraft are provided. A method may comprise the steps of receiving a request, aimed at receiving avionic data from avionic systems, from a non-avionic client device; determining the distance between the non-avionic device and the cockpit of the aircraft; and adjusting the sending of data in response to the request depending on the determined distance. Developments of the invention describe the use of a wireless access point associated with a secure gateway determining the access rights to the avionic data for the non-avionic device, various sending and/or display adjustments depending notably on the distance, threshold management, various indoor positioning techniques, unilateral or bilateral communications, various notifications, the use of lightweight connected clients (for example earpiece, watch, glasses, etc.).

Continuity of access to avionic data outside of the cockpit of an aircraft

A method implemented by computer in or for a flight management system or FMS, comprises the steps of receiving requests issued by clients; determining a correspondence between the requests and predefined unitary services executable by at least one server associated with the FMS; queuing the unitary services determined in one or more queues; determining a response time associated with each request; and notifying at least one client of the response time to its request. Developments describe the processing of queues, the management of priorities, the existence of fixed-price contracts, caching mechanisms, interruptions of queues, cancellations of requests, voting mechanisms, etc. The unitary services in particular can be avionics services of ATA (Air Transport Association) type. Systems aspects and software aspects are described.

Quality of service of a flight management system

The system executes services by an application called 'server' for at least one application called 'client.' A preliminary step establishes for each service a list of calculation parameters that can be varied in a given range, called &#x201c;adjustable parameters&#x201d; as well as time and quality of the said service information according to the value of the said parameters. At the request of a client for a given service, the method adjusts the value of the adjustable calculation parameters as a function of a given constraint, the service being executed using the adjusted values of the said parameters.

Adaptive method for the execution of services in real time, notably of flight management and real time system using such a method

A system executes services by a 'server' for a 'client'. A preliminary step establishes a list of available services of the server, set up for the client, in which a processing time is determined releasable by the server for the client per code execution cycle minor frame (&#x201c;MIF&#x201d;). The system creates on start-up: NT execution tasks for the client, each having a priority of execution level and an allocated average duration of execution, a number of execution tasks (NT) being at least 1, the sum of durations of the tasks being at most the releasable processing time; execution rules associating each of the tasks with at least one service of the list; then, during each MIF cycle, the system executes the services on their associated tasks, a task executed by priority and for at most its allocated average time of execution, the non-executed part of a service being executed on its associated task in the next cycle.
