Simrad AP26, AP27 manual NAV Mode, Wind Mode, Response, Wind response

Installation

Response

The Autotune function in the AP26 and AP27 is so refined that 80-85 % of the boats will need no further adjustments of the steering parameters. On some boats, however, or at particular sea conditions a fine tuning of the steering parameters may improve the performance of the autopilot.

The Response control allows you to make this fine tuning. It can be set to seven levels. Level 3 (default) has the values of Rudder and Counter Rudder parameters set by the Autotune function. If no Autotune is made (not recommended) the level 3 values are the factory default values.

A low response level reduces the rudder activity and provides a more “loose” steering.

A high response level increases the rudder activity and provides a more “tight” steering.

A too high response level will make the boat start S-ing. Range: 1 – 7

Default: 3

NAV Mode

The User setup for NAV mode is identical to the User setup for AUTO mode.

WIND Mode

The User setup for WIND mode includes the same items as the User setup for AUTO mode. In addition you have:

Wind response

If the difference between the set wind angle and the actual wind angle is too big, the ‘Wind response’ can be increased to reduce the deviation.

Note ! First make sure that the course keeping is acceptable, i.e. the difference between the Course To Steer (CTS) and the actual heading is at a minimum.
