Probing the Airborne Omega Environment
Joseph J Scavullo · NAVIGATION Journal of the Institute of Navigation · 1977
Prospective users have begun to request the Federal Aviation Administration (FAA) to certify the Omega Navigation System over oceanic jet routes and over the routes of offshore oil–lease areas. The FAA has sampled the quality and coverage of Omega signals in many of these areas. Data recorded during a number of probe flights has been consistent with forecasts of coverage as well as with predicted gaps due to large discontinuities along the propagation pathway, such as the dielectric ice mass on Greenland. The paper proposes to extend in–flight data collection all around the world during the imminent rising portion of the next sun spot cycle. It outlines a plan to develop a bank for the data and to publish a running account of the findings under a cooperative industry–government effort.
