AMPHIBIOUS CONTROL CRITERIA
While similar to carrier operations, amphibious operations have different control
procedures and separation standards. Controllers must have a comprehensive
knowledge of these procedures and standards to provide safe and expeditious air traffic
control service on an LHA or LHD.
Control Procedures
Existing weather in the ship's control area and control zone is the most prominent factor
affecting the type of departure and/or recovery. Just like carrier operations, the three
types of departure and recovery operations are Case I, II, or III. The Air Ops officer
determines the case of operations to use during departure and recovery operations. The
AATCC exercises one of four degrees of control-positive control, advisory control,
monitor control, or NONRADAR control.
Case of Departure and Recovery
Weather in the control zone is the most prominent factor affecting the degree of control
necessary. The type of control to be employed during departures and recovery is
determined by the Air Officer (after coordination with the LSO, AATCC Officer, and Air
Operations Officer) unless otherwise specified by higher authority (see Table 11-18).
