If departing OLF Spencer on course 270, which departure corner applies?

Explanation:
Departures use a simple quadrant rule: the field is divided into four corners, and the outbound course determines which corner you fly toward to stay in the published departure corridor and keep clear of obstacles. Heading 270 means you’re flying west. The standard one for a westbound departure is the Northwest corner, which places your initial climb path into the western-north quadrant and keeps you aligned with the intended departure flow. That’s why the Northwest corner is the correct choice here. If you were departing on a different heading, a different corner would apply corresponding to that outbound direction.
