1. A method for exchanging data between a first group of at least one on-board equipment of an aircraft configured to supply functioning measurements of at least one aircraft system, and a second group of at least one smart mobile device in communication with and mobile in relation to said at least one on-board equipment, the method implemented as part of an operation of remote maintenance of the aircraft in flight, comprising the steps of:

  • transmitting at least one request for a measurement data from said at least one smart mobile device to said at least one on-board equipment, following a tree structure of the measurement data to be acquired by said at least one smart mobile device or a supplementary tooling from a set of on-board equipment;

    receiving a piece of measurement data in response to said at least one request from said at least one on-board equipment, the piece of measurement data received by said at least one smart mobile device causes a passage to a later step in a tree structure of measurement data requests referred to as an interactive maintenance document;

    generating the interactive maintenance document on a basis of an aircraft technical documentation by;

    adapting procedures included in the aircraft technical document for the aircraft in flight;

    automatically extracting, from the aircraft technical document, inferences, data to be measured, remote measurements and remote actions achievable on said at least one on-board equipment, remote measurements and remote actions requiring a tool not included in said at least one on-board equipment; and

    wherein the interactive maintenance document comprises a set of branches, each branch comprising at least one step of acquiring a measurement, whose result is validated positively or negatively to progress to a next step and to obtain a diagnosis of a failure based on the measurements;

    identifying a component to be replaced or repaired in accordance with the diagnosis of the failure; and
