1. Device for calculating a flight plan of an aircraft, the flight plan making it possible to meet up with an initial flight plan, the aircraft comprising sensors for detecting surrounding moving objects and weather sensors for detecting meteorological phenomena, the device comprising means for:
- a. determining parameters of the moving objects detected on the basis of data originating from the sensors for detecting surrounding moving objects;
b. determining parameters of the meteorological phenomena detected on the basis of meteorological data originating from the weather sensors;
c. calculating prohibited zones and their evolution over time on the basis of the parameters characterizing the moving objects and the meteorological phenomena detected, the prohibited zones defining a space where the aircraft cannot fly;
d. calculating zones reachable by the aircraft and their evolution over time on the basis of;
i. a position of the aircraft;
ii. data describing regulated zones prohibited to navigation;
iii. a digital terrain model; and
iv. a list of obstacles and prohibited zones calculated;
e. selecting a joining point meeting up with the initial flight plan situated in a reachable zone; and
f. calculating a joining flight plan for meeting up with the selected joining point.

Abstract
The invention relates to a device for formulating a flight plan ensuring sufficient safety margins for a duration of a few minutes in relation to the set of flight constraints that could arise and comprising means for:
- detecting the surrounding moving objects (aircraft or meteorological phenomena),
- evaluating their type and the danger that they represent,
- formulating a reconfiguration flight plan ensuring a separation with these phenomena and taking best account of the constraints of the initially followed flight plan, avoiding prohibited or regulated airspaces and avoiding the surrounding relief with ad hoc operational margins.
