Radio altimeters don't suffer from these problems. They're simpler and work in a similar way to radar (the system planes, ships, and other vehicles use to navigate): they just fire a beam of radio waves down from the plane and wait for the reflections to return. Since radio waves travel at the speed of light(300,000 …
