Non radar separation standard is what?

• A. 5 Minutes / 10 Miles
• B. 15 Minutes / 25 Miles
• C. 10 Minutes / 20 Miles
• D. 2 Minutes / 5 Miles

Answer: (C)

Non-radar separation relies on time or distance between aircraft because radar tracking isn’t available. The standard used is the greater of a time-based and a distance-based minimum, so you ensure either at least ten minutes between position checks or at least twenty miles of separation, whichever provides the larger margin given the aircrafts’ speeds and reporting intervals. This approach protects safety when you can’t continuously monitor with radar and speeds or reporting can vary. Other options would yield smaller separations and aren’t acceptable as the baseline in non-radar operations.
