- Q126 - Navigation Problems: Near Coastal
183. On 28 July your 1937 zone time DR position is LAT 26°13.0' N, LONG 78°27.0' E. At that time, you observe Deneb bearing 048.7°pgc. The chronometer reads 02h 37m 42s, and the chronometer error is 00m 15s fast. The variation is 4°W. What is the gyro error?
The computed true azimuth of Deneb (051.5T) exceeds the observed gyro bearing (048.7pgc) by 2.8, indicating a gyro error of 2.8E.
