A method (20) for calculating lateral avoidance trajectories for an aircraft (11). The method includes: obtaining data indicative of current aircraft position, current track, current roll, current airspeed, current vertical speed, current altitude, and maximum achievable roll of the aircraft; calculating a current trajectory of the aircraft; and calculating a left trajectory and right trajectory of the aircraft corresponding to the aircraft turning left/right at the maximum achievable roll from the current aircraft position. The method also includes obtaining local terrain elevation grid data; determining intersections between the local terrain elevation grid, and each of the current trajectory, left trajectory, and right trajectory; and providing an indication, of any intersections between the local terrain elevation grid, and each of the trajectories.
