In a Case II jet departure, after clearing turn, at how many nautical miles should the aircraft turn to intercept the arc?

Case II jet departures are designed so you join a published arc by turning at a precise distance after the clearing turn. The seven-nautical-mile point is chosen because the arc’s radius, your typical climb speed, and a standard pilot turn will place you on a tangent to the arc at that distance. Intercepting at that point ensures a clean, predictable path onto the arc while maintaining obstacle clearance and proper spacing with other traffic. If you started the turn earlier, you’d intercept the arc at an steeper or awkward angle, risking an unstable transition or encroachment on protected airspace. If you wait too long, you’d miss the intended intercept point and could overshoot the arc or fail to join it within the required airspace constraints.
