1. A method for creating a representation of a safe termination operation volume indicating a lowest allowable flight altitude to achieve a glide path of a vehicle to a termination point of an area of interest, the method comprising:
- taking non allowable fly zones into consideration by adding flight altitude to come around said non allowable fly zones when calculating the lowest allowable flight altitude;
discretising the area of interest into discretised areas;
inputting data concerning No fly zones and Lift and Drag ratio;
selecting at least one point defining a termination point;
computing the lowest allowable flight altitude for points adjacent to the point defining the termination point, wherein the lowest allowable flight altitude is computed to admit gliding of the vehicle to the lowest allowable flight altitude of the point defining a termination point;
repeating the computing of the lowest allowable flight altitude for point adjacent to the point previously computed, wherein the lowest allowable flight altitude is computed to admit gliding of the vehicle to the lowest allowable flight altitude of the previously computed point; and
repeating the computing and repeating the computing for all selected termination points until all points of the discretised area have received a lowest allowable flight altitude, resulting in a bottom surface of a safe termination operation volume.

Abstract
A method of forming a safe termination operation volume, and an aircraft provided with a system using such a volume to plan a flight route and/or an emergency route. The volume indicates the lowest allowable flight altitude to achieve a glide path of a vehicle to a termination point of an area of interest, wherein non allowable fly zones are taken into consideration by adding flight altitude to come around the non allowable fly zones when calculating the lowest allowable flight altitude.

14. A computer program product, comprising:
-
a computer readable medium; and computer program instructions recorded on the computer readable medium and executable by a computer to carry out a method of creating a safe termination operation volume comprising taking non allowable fly zones into consideration by adding flight altitude to come around said non allowable fly zones when calculating the lowest allowable flight altitude, discretising the area of interest into discretised areas, inputting data concerning No fly zones and Lift and Drag ratio, selecting at least one point defining a termination point, computing the lowest allowable flight altitude for points adjacent to the point defining the termination point, wherein the lowest allowable flight altitude is computed to admit gliding of the vehicle to the lowest allowable flight altitude of the point defining a termination point, repeating the computing of the lowest allowable flight altitude for point adjacent to the point previously computed, wherein the lowest allowable flight altitude is computed to admit gliding of the vehicle to the lowest allowable flight altitude of the previously computed point, and repeating the computing and repeating the computing for all selected termination points until all points of the discretised area have received a lowest allowable flight altitude, resulting in a bottom surface of a safe termination operation volume.
