For a Case II turboprop departure parallel to the BRC at 500 feet, at how many nautical miles should the turn to intercept the arc occur?

Joining the arc from a straight, parallel departure depends on turning geometry: you need to start the turn far enough in advance so that, with a standard‑rate turn, you finish the turn and align with the arc at the right position. For a Case II turboprop departure, the standard‑rate turn (about 3 degrees per second) at typical departure speed gives a turn radius on the order of roughly 0.8–1.0 NM. Starting the turn about six nautical miles from the arc provides enough distance to complete the turn and intercept the arc smoothly, without overshooting or arriving too late. Starting closer would risk incomplete alignment; starting farther would delay the intercept. So six nautical miles is the distance that yields the correct intercept geometry and safe sequencing.
