What should NOT be done when two aircraft are approaching for landing?

The chosen answer highlights a critical aspect of safe aviation practices. Cutting in front of another aircraft on final approach disrupts the established order of landings and poses serious collision risks. When two aircraft are approaching for landing, it's vital for pilots to maintain a safe and predictable flow of traffic. Each aircraft should respect the established spacing and order dictated by altitude, speed, and communication with air traffic control.

Maintaining proper separation during approach is essential for ensuring safety and efficiency in landing operations. If one aircraft cuts in front of another, it can lead to a conflict where the aircraft may not be able to respond effectively to avoid a collision, thus compromising the safety of both flights. Proper etiquette when landing ensures a clear and organized approach path, allowing for smooth operations in the airspace and on the runway.

The other options reflect safer operational procedures that prioritize the safety and coordination necessary in these situations.
