A method to manage approaches to a platform (in particular at sea and operated by a helicopter) comprises the steps of receiving initial parameters and determining four particular waypoints (called IAF, IF, FAF and MAP). These flight plan points respectively determine the starting point of the approach procedure, the intermediate point corresponding to the end of the initial alignment and to the start of the capture of the final approach axis, the starting point of the final approach, and the point of decision to terminate the approach or initialize a go-around. Different developments describe different types of approaches that can be achieved by this method, the management of the descent and speed profiles, the management of the safety distances and the management of the display of the piloting instructions. Software and system aspects are described.
