Separation Criteria
Specific separation standards apply to amphibious aircraft operations. Controllers will
use these standards to separate, sequence, and vector aircraft to and from ships.
These separation standards do not apply to tactical maneuvers such as air intercept
rendezvous.
Lateral Separation
Table 11-20 shows how lateral separations are used for amphibious operations.

NOTE
Air Search Radars that rotate in excess of 7 rpm are the
only radars acceptable for an ASR approach and for
applications of lateral separation of less than 5 nm.
