3.4 Rudder angle alignment
With the rudder amidships, see if the rudder angle display reads zero.
Misalignment up to +/- 7 degrees can be removed in the calibration
sequence which is explained later in this section. If the misalignment is
greater than 7 degrees the rudder reference should be mechanically
adjusted to be within the +/- 7 degree limit.
