Abstract
A distance from an aerial vehicle to a terrain feature located forward and lower with respect to the aerial vehicle is measured. A current orientation of the aerial vehicle with respect to a reference orientation is detected. At least the measured distance and the current orientation is utilized to determine a relative vertical difference between a vertical location of the aerial vehicle and a vertical location of the terrain feature. The determined vertical difference is utilized to automatically adjust a flight altitude of the aerial vehicle.
