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.).
