- Q142 - Navigation Problems: Oceans
166. On 22 March your 0519 DR position is LAT 27° 20.6' N, LONG 69° 25.6' W. You observe an unidentified star bearing 051° T at an observed altitude (Ho) of 50° 03.7'. The chronometer reads 10h 16m 47s, and is 02m 15s slow. What star did you observe?
Deneb is the correct answer because its predicted altitude and bearing, calculated using the chronometer-corrected time and DR position, match the observed values.
