7. Heading

After the Heading Selector has been installed and

Selector

all connections have been made, proceed with the

following:

a. Start the gyrocompass and wait

for it to settle.

b. Set HEADING SELECTOR control to

the same heading as that indi-

cated by the gyrocompass card.

Energize the steering equipment

and position the rudder to amid-

ships. Place control equipment

in the gyrocompass mode.

d. Set HEADING SELECTOR control

first to the right, then to the

left of the actual heading as

indicated by the gyrocompass

card. The rudder should move

so as to turn the vessel toward

the ordered headings.

e. When the rudder does not respond

properly in Step d, turn the

HEADING SELECTOR control to-the

point that the rudder stops at

amidships. When the rudder

cannot be positioned with this

control, check the steering

equipment. When no problem is

found with the steering equipment,

check the HEADING SELECTOR

alignment.
