Abstract : Daily engine checks or health tests are being developed for determining the condition of an engine by relating significant performance parameters. One such health test, termed 'HIT,' utilizes exhaust gas temperature along with compressor speed. Since results of this test vary with outside air temperature conversions must be made by maintenance personnel and pilots. A calculating device is provided for this use. (Author)
