- Q127 - Navigation Problems: Oceans
178. On 22 March your 0519 DR position is LAT 27° 20.6' N, LONG 69° 25.6' W. You observe an unidentified star bearing 115° T at an observed altitude (Ho) of 54° 52.8'. The chronometer reads 10h 16m 47s, and is 02m 15s slow. What star did you observe?
Altair is the correct answer because its position, when used in sight reduction with the corrected GMT and DR position, produces a computed altitude and azimuth that closely match the observed values.
