Aircraft Fixes changed to Degrees and decimals.
1730Z..20.32/ 64.88
1907Z..20.37/ 65.33 290degrees for 25.5nm
2057Z..20.53/ 65.75 306degrees for 25.5nm
2307Z..20.60/ 66.17 293degrees for 23.8nm
From 1730Z fix to 2307Z fix, the distance is 74.3nm with an Average heading of 297degrees.
So 297degrees is the average, but you can see the different point to point headings.
**These are Recon fixes and NOT the Official NHC fix. This was just and example of how the headings change from time to time and NHC uses an average for their Advisories.**
