If you observe steady red and green lights at the same altitude during a night flight, what conclusion can you make about the other aircraft?

  1. The other aircraft is flying away from you

  2. The other aircraft is approaching head-on

  3. The other aircraft is crossing to your right

  4. The other aircraft is climbing

The correct answer is: The other aircraft is approaching head-on

Observing steady red and green lights at the same altitude indicates that the other aircraft is approaching head-on. In aviation, the red light is typically on the left side of an aircraft and the green light is on the right side. When you see both lights in a steady manner, it means that you are likely seeing the other aircraft's lights directly, which signifies that it is coming toward you. In the context of flight rules, any aircraft that is approaching head-on will show the red light of one aircraft and the green light of the other, leading to the conclusion that there is a potential for a mid-air collision, and both pilots should take actions to avoid each other.
