Steer-Pilot Mode You can use the marine instrument to help you steer using a specific wind angle or information received from connected sensors and a GPS device. You can also use the marine instrument to help when tacking. Using Steer-Pilot Mode with the AWA or TWA Setting Before you can use steer-pilot mode with the Apparent Wind Angle (AWA) setting, you must connect the instrument to a wind sensor, either wirelessly or through the NMEA 2000® network. Before you can use steer-pilot mode with the True Wind Angle (TWA) setting, you must connect the instrument to a wind sensor, either wirelessly or through the NMEA 2000 network, and you must connect it to a speed sensor or GPS device through the NMEA 2000 network. You can enter a specific wind-angle value and use the instrument as a steering guide when sailing. 1 From an instrument screen, hold .
