Under which condition should a first officer refrain from conducting takeoffs or landings based on logged hours?

The best approach for a first officer regarding takeoffs or landings is to consider their logged experience and the operational conditions affecting flight safety. Each listed condition reflects a critical aspect of safe aviation operations.

When wind shear is reported, it creates a significant hazard during takeoffs and landings. Wind shear can cause sudden changes in wind direction and speed, making it challenging for even experienced pilots to maintain control during these critical phases of flight. It is prudent for a first officer to refrain from these maneuvers until they have sufficient experience to handle such conditions effectively.

Logged hours are also a vital factor. If a first officer has logged fewer than 100 hours, they may not have had adequate experience with the complexities of different aircraft operations, particularly takeoffs and landings. This limitation emphasizes the need for proficiency and confidence, which invariably improves with increased flight experience.

Additionally, when braking action is reported as less than "Good," it directly impacts the safety of takeoff and landing. Poor braking conditions can lead to longer landing distances or a compromised ability to stop the aircraft in an emergency. Refraining from takeoff or landing in such conditions safeguards not only the crew and passengers but also the integrity of the aircraft.

Collectively, all these points underscore the
