Australia Instrument Flight Rating (IFR) Practice Test

During night flight under IFR (Instrument Flight Rules), having anti-collision and position lights is crucial for enhancing safety. Anti-collision lights increase the visibility of the aircraft to other pilots and ground personnel, alerting them to its presence and reducing the risk of mid-air collisions. Position lights indicate the aircraft's orientation—red on the left wing and green on the right—as well as the white light at the tail, which helps other aircraft understand your movement and direction.

While position lights are essential for showing your location and heading to others, anti-collision lights further augment this by making the aircraft stand out. Together, they form a critical part of the safety equipment required for night operations, allowing for better situational awareness for both the pilot and other air traffic, which is particularly important in lower visibility conditions often found during night flying.

The other options do not provide sufficient safety measures. Relying solely on position lights, outside landing lights, or just the pilot's map light would not adequately enhance visibility or prevent collisions, which is why those combinations are not deemed sufficient for safe IFR nighttime operations.
