If an aircraft flies on a bearing of 120 degrees from point A to B, what bearing should it take to fly from B to A?

Just add 120 with saprementary 120+180=300

the opposite direction: 120+180 = 300

To determine the bearing the aircraft should take to fly from point B to point A, you need to add or subtract 180 degrees to/from the initial bearing of 120 degrees.

Since you are going in the opposite direction, you need to add 180 degrees to the initial bearing.

Therefore, to fly from point B to point A, the aircraft should take a bearing of 120 degrees + 180 degrees = 300 degrees.

To find the bearing the aircraft should take to fly from point B to A, we need to subtract 180 degrees from the initial bearing of 120 degrees.

Here's how you can calculate it step by step:

1. Start with the initial bearing of 120 degrees.

2. Subtract 180 degrees from the initial bearing to find the new bearing.

Bearing B to A = 120 degrees - 180 degrees = -60 degrees

Therefore, the aircraft should take a bearing of -60 degrees to fly from point B to point A.

Note: Bearings are often measured in degrees clockwise from north, with north being 0 or 360 degrees. In this case, we have a negative bearing because it is measured clockwise from the south.
