Helicopters launch on the assigned departure radio frequency instead of the
land/launch frequency and monitor guard frequency. PriFly monitors the
departure frequency.
Helicopters that launch on tactical missions rendezvous as briefed, report KILO,
and switch to an assigned tactical control agency.
Similar types of aircraft may launch at 1-minute intervals. If RADAR contact is
established within 1 mile after takeoff, AATCC may clear the next aircraft to
depart. During mixed operations, there must be a 2-minute interval between the
last helicopter and the first fixed wing aircraft.
NOTE
Modifications to Case III procedures are not authorized.
Departure Patterns
Standard amphibious IMC departure patterns are shown in Figure 11-8.
Figure 11-8 -- Case III helicopter departure patterns.
Fixed Wing Departure Procedures
Due to mission and aircraft characteristic differences, fixed wing aircraft use different
departure procedures than helicopters. Departure controller must know these departure
procedures and monitor aircraft compliance.
