What is the approximate bearing to the northwest corner of TAMUCC when landing RWYs 13 L/R, 18, or 22 at PT SHAMROCK?

Bearings are the direction to a point, expressed clockwise from north, and in aviation you use magnetic north for cockpit navigation. From PT SHAMROCK to the northwest corner of TAMUCC, the line points mainly west but with a slight southern component, so the direction sits a bit south of due west. That places it around 255 degrees. The true bearing would be a few degrees higher, but local magnetic variation in the Corpus Christi area (west variation) reduces it to about 255 degrees for practical, magnetic navigation. The runway you’re landing on doesn’t change this fixed directional line to the northwest corner; it only affects your approach path to the runway.
