Certain aspects of the present disclosure provide a method for determining a flight plan for an aircraft, including: determining one or more regions that intersect an initial flight path and comprise at least one terrain feature having an elevation greater than an elevation threshold; for each respective region: determining a flight area based on the initial flight path and an elevation threshold line; determining one or more segments of the initial flight path that comprise one or more terrain features having an elevation greater than the elevation threshold; and determining a modified flight path for each respective segment by: determining a plurality of descent gradients along the respective segment; and moving the respective segment of the initial flight path in the safe descent direction if any of the plurality of descent gradients would collide with any of the one or more terrain features.
