Show Greater Safety in the Air Greater safety in flight is assured as-sured by the development of an absoute altimeter, which shows actual ac-tual height above the ground instead in-stead of above sea level. Per example, the bariimetric altimeter al-timeter might show a reading of 4,000 feet when the airplane is passing pass-ing pver mountains that are 3,800 feet high. The new instrument, in such a case, would show the true reading, 200 feet. Even the laymen can readily see the imlmense contribution that this machine makes to the safety of airplanes. air-planes. Many accidents have been caused by fog, rain and clouds which prevented pilots from knowing know-ing exactly where they were flying and, for that reason, from knowing that dangerous crags were ahead of them;. The new machine uses shortwave short-wave radio, is entirely free of stactic and conditions of fog and storm. It is something to cheer about. |
