During Case III departures, helicopters shall arc at how many miles to intercept assigned departure radials?

The idea here is to use a controlled curved path to smoothly bring the helicopter onto its assigned departure radial. An arc distance that is not too tight and not too long provides the best balance: it lets you maintain a stable, coordinated turn, keep the aircraft within ATC radar coverage, and position you for a clean intercept without overshooting. If the arc is too tight, winds and pilot workload can make the intercept accuracy suffer and increase maneuver stress. If the arc is too long, it delays getting onto the outbound radial and ties up airspace longer than necessary. The chosen arc distance sits in the middle, delivering a reliable, predictable transition from takeoff to the outbound course and enabling ATC to sequence traffic effectively.
