FAA En‑Route Radar Controller Certification (CKT-1) Practice Test

The minimum vertical separation required for aircraft on divergent courses immediately after takeoff is 1,000 feet. This standard is established to ensure a safe distance between aircraft that are climbing out in different directions, thereby reducing the risk of collision and providing adequate spacing during an operation that involves two aircraft departing closely in time. Maintaining 1,000 feet of vertical separation helps cushion any unintentional altitude deviations that could occur during takeoff and initial climb, ensuring a higher level of safety in the vertical dimension.
