During VFR takeoff from runway 13R, what is the initial heading after becoming airborne?

After becoming airborne from runway 13R, the initial heading would be 138º. This is because runway headings are typically referenced in terms of their magnetic orientation, and runway designations correspond with their compass heading rounded to the nearest ten degrees.

Runway 13R is aligned approximately at a heading of 130º, and upon takeoff and initial climb, pilots will typically maintain a heading that steers slightly left of the runway for safety and procedural reasons, adjusting for any air traffic control instructions or local procedures. In this case, the initial turn after takeoff would lead to a heading of approximately 138º.

Understanding how runway numbers correlate with their magnetic headings is essential for pilots. This knowledge assists in navigation and traffic patterns in the vicinity of the airport. Therefore, the answer is based on standard procedures following takeoff and the orientation of the runway.
