Abstract
The apparatus comprises an interference calculator (2), elements (3) for acquiring parameters relating to the aircraft and to the outside environment, a memory (4) for storing a constructed route, a memory (5) containing a model of the terrain to be overflown, display elements (6), an interactive graphics route-construction tool (7), a navigation calculator (8), and a piloting system (9), together with at least one elements (12) for providing assistance in perceiving the environment outside the aircraft.

9. A method of making flight safe for a rotary wing aircraft, the method comprising:
-
a) constructing a route for the aircraft;
b) causing the aircraft to follow the route thus constructed; and
c) at least in part while following the route, calculating interference, if any, between the constructed route, a model of the terrain overflown, and parameters relating to the aircraft and to its outside environment, in order to determine a route that is safe;
wherein, in order to enable the method to offer the aircraft the capacity to fly in all weathers and at any location, the method further comprises;
constructing at least the initial segments and possibly the entire route; and
while following the route, and independently of any instrument flight infrastructure, performing the making-safe operations of step c) on board the aircraft, with acquisition of parameters relating to the terrain overflown, to the aircraft, and to its outside environment, and performing the following operations automatically;
α
) verifying the safety of the actual route of the aircraft;
β
) verifying the safety of the aircraft flight relative to parameters acquired on board; and
γ
) providing on board the aircraft assistance in perception by presenting interferences, parameters relating to the terrain overflown, to the aircraft, and to its outside environment. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
