What is dip angle?

The dip angle, I (for inclination), is the angle that the total field vector makes with respect to the horizontal plane and is positive for vectors below the plane. It is the complement of the usual polar angle of spherical coordinates. Can you refill a compass? Hold the compass in one hand and pick up the syringe with the other hand. Insert the tip of the syringe into the fill hole of the compass and inject enough compass oil into the compass to fill it. Gently jostle the compass as before to ensure that there are no other trapped air bubbles in the compass.

Can you use magnetic compass on autopilot?

Since the compass is an electronic one, the scope of errors is greatly reduced. In addition to manual steering, such a compass can also be utilised when the ship is on autopilot. Even chartplotters and radars use this system to provide them with accurate geographic indications. One may also ask can you fix a compass?
