Bearings & Direction Flashcard

Front

What is a bearing in navigation?

Back

A bearing is a direction or angle measured in degrees from a reference direction, typically north, used to describe the direction of one point from another.

How do you express a bearing of 302° as a compass directional bearing?

Back

N58°W

If a sailboat leaves the dock heading N30°E and travels 100 kilometers, how far east of the dock is the sailboat?

Back

50 km

Convert the compass bearing S45°E to a true bearing.

Back

135°

Convert the compass bearing S30°W to a true bearing.

Back

210°

What is the true bearing for N76°W?

Back

284°

Front

What is the difference between true bearing and compass bearing?

Back

True bearing is measured clockwise from north, while compass bearing uses cardinal directions (N, S, E, W) to indicate direction.

Front

How do you calculate the eastward distance from a bearing?

Back

Use trigonometric functions: Eastward distance = distance * cos(bearing angle).

Front

What is the formula to convert compass bearings to true bearings?

Back

For bearings in the first quadrant (N), true bearing = angle; for S bearings, true bearing = 180° + angle.

Front

What is the significance of bearings in navigation?

Back

Bearings help in determining the direction to travel from one point to another, essential for navigation.
