Bertrand Larrieu: Low-altitude piloting method. Sextant Avionique, Oblon Spivak McClelland Maier & Neustadt P C, July 13, 1999: US05922031 (20 worldwide citation)

In a method for the piloting of an aircraft, enabling low-altitude flight by setting up a tangent with the relief to be overflown, the aircraft pilot determines the goals to be attained on a cartographic screen. This is done in enabling a computer, using altimetrical data, to define a ground profile ...
