Final answer:
When observing a steady white light and a flashing red light ahead on another aircraft during a night flight, it indicates that the aircraft is flying away from you.
Step-by-step explanation:
During a night flight, when you observe a steady white light and a flashing red light ahead and at the same altitude, it usually implies the orientation of the lights on another aircraft. The steady white light is typically located at the tail of the aircraft, while the flashing red light is on the left wing. Considering standard aviation lighting, the general direction of movement of the other aircraft is that it is flying away from you. The red navigational light is on the left (port) wing, and the white light is on the tail, so seeing both of these at the same altitude ahead would mean the other aircraft's direction of travel is away from yours.
