Nonradar separation with a published approach/departure minimum is what?

In nonradar operations, when two aircraft are following a published approach or departure, separation can be maintained using the fixed spacing guaranteed by that procedure rather than radar guidance. The standard spacing is two minutes, which translates to about five miles behind the leading aircraft at typical speeds. Because these two ways of expressing the same separation describe the same safety margin, the requirement is stated as two minutes or five miles. This ensures obstacle clearance on the published path without radar. So the best choice reflects that equivalence: two minutes, five miles. The idea is that either measure can be used depending on what’s easier to apply, as long as the trailing aircraft can maintain that spacing on the same published procedure.
