Magnetic variation
(Required for magnetic bearings) Also known as magnetic declination, this is the difference between magnetic north and true north; positive when magnetic north is east of true north, negative when west. Click to look up the magnetic variation based on the 1st waypoint.
:
°
Reference bearing
(Optional) Calculate bearings relative to this reference, either a numerical direction between 0 and 360 or a direction symbol, e.g., NE, SSW, etc. The compass rose points to this direction. Set this to the wind direction, to compute bearings relative to the wind; P means port, S means starboard. The solid arrow should point to where the wind is coming from, like a weather vane.
:
°
AoA
(Optional) Minimum and maximum desired Angle of Attack (AoA), relative to the reference bearing. A red warning sign
is displayed besides any course which exceeds either one of these parameters. Note that leeway is not taken account. On a port tack your heading is increased by your leeway, and on a starboard tack it is decreased.
