He verified all his instruments—the map-holder, the compass, the altimeter, the tachometer, the speedometer—with searching care. The altimeter showed that he was hovering at eight thousand feet above ground-level. The altimeter was trying to keep up with the boat and just couldn't, half the time. They had fired at me two hundred times: my bullets, before the breakdown, had gone through their altimeter and their tachometer, which had caused their excitement. Examples of altimeteraltimeter The case is made that radar altimeter data can be used to monitor changes in glacier topography related to climate change and surge events. Such changes in snow structure are important as they may influence radar altimeter returns. The altitude at each point was measured using an altimeter. A third source of data, also from the field, is derived from a satellite altimeter. It was not until almost 10 years later, however, that theory was turned into reality with the first radar altimeter missions. The radio altimeter is a facility which is regarded primarily as an adjunct to other systems in approach and landing in low weather conditions.
