Pilot Type
The pilot type screen enables you to define your autopilot
configuration as follows:
•
DISPLACE (displacement)
• SEMI alternating with DISPLACE (semi-displacement)
• PLANING
• STERN DRV
The pilot type screen is displayed only when the User Setup routine is
entered for the first time and only when the ST7000 Plus is being used
in conjunction with a Type 100/300 Course Computer using Software
Version 11 or later.
Compass Deviation Correction (SWING COMPASS)
The compass deviation correction option allows you to correct the
compass for deviating magnetic fields. The procedure must be
performed as the first item in your initial sea trial, and is described in
detail in Chapter 6, Post Installation Procedures.
Deviation Display (DEVIATION)
The deviation screen shows the current deviation value, calculated
from the correction procedure (
SWING COMPASS). You cannot edit this
value.
Heading Alignment (ALIGN HDG)
The heading alignment screen shows the current reported heading.
Note: You should always check the compass alignment after
performing a compass deviation correction (see Chapter 6, Post
Installation Procedures). However, once the initial correction
procedure has been performed, you can make adjustments to the
alignment as often as you wish, without re-correcting your compass.
• Steer your vessel onto a known heading, and check the heading
displayed.
• If required, adjust the heading value to match the known value,
using the +1, -1, +10 and -10 keys.
