In non-radar operations, what condition allows simultaneous departures from parallel runways on a given set of centerlines and courses?

• A. 3,500 ft separation; 30 degrees divergence after takeoff
• B. 3,500 ft or more; 45 degrees immediately after takeoff
• C. 4,000 ft separation; 60 degrees after takeoff
• D. 2,000 ft separation; 15 degrees after takeoff

Answer: (A)

In non-radar operations, safe simultaneous departures from parallel runways rely on both fixed lateral separation and immediate divergence of the flight paths. The runways must be at least 3,500 feet apart, and the aircraft must diverge by 30 degrees from the parallel centerlines right after takeoff. This combination ensures the two aircraft quickly separate laterally without radar guidance, reducing the risk of conflict as they climb.

The other options don’t fit because they either require more distance than necessary, a larger or smaller divergence angle than prescribed, or insufficient initial separation.
