Mode III is manual pilot control
with talkdown guidance by a shipboard controller that
provides verbal information for pilot control to visual
minimums. The pilot can use full Mode I capability
with Mode II and Mode III as backups.
The landing sequence begins when the aircraft is
at the marshaling point (fig. 9-2) under control of the
carrier air traffic control center (CATCC). The
sequence is in two phases: approach and descent.
Flight from the marshaling point to the radar
acquisition window is the approach phase. Flight
from the radar window to touchdown is the descent
phase. Transition from the approach phase to the
descent phase is done with a minimum of switching
operations to reduce pilot task loading.
MODE I LANDING OPERATION
Figure 9-3 shows the Mode I landing sequence.
The sequence begins when the aircraft is at the
marshaling point. Here the aircraft is held according
