Ahh, true heading - OK.
What is unclear is why there is also a connection to latitude and longitude.
I looked at the airports - based on data from
https://www.airnav.com these are the deviations in degrees from 270:
82V -0.009377087
KBJJ 0.001984966
KCIU -0.024015687
KCNM 0.017476942
PABR -0.00926391
AirNav provides Lat/Long for each end of the runway which I converted with ATAN to a degrees variation. It did not list the last two.
SKLM, is listed as runway true heading: 272.4 on
SKLM - Jorge Isaac Airport and
SYCJ is listed at 271.9
So it's a mystery. While I can imagine truncating the true heading to one place would be a problem, I can't see where they would truncate the true heading by more than 2 degrees.
