What is a requirement for taking off or landing at a night aerodrome?

Taking off or landing at a night aerodrome requires that the aerodrome must be adequately lighted. This is crucial for ensuring the safety of flight operations during nighttime when visibility can be significantly reduced. Adequate lighting helps pilots to identify the runway, taxiways, and any potential obstacles, enabling them to make safe landings and takeoffs.

Having proper lighting at an aerodrome plays a fundamental role in flight safety protocols during night operations. Pilots rely on visual cues that lighting provides to navigate and position the aircraft correctly when landing or taking off in darkness, which is particularly important in preventing accidents.

The other options, while they may involve different safety measures, do not specifically address the critical need for adequate lighting at night aerodromes. For instance, filing a flight plan is generally a good practice and may be required under certain conditions but does not directly pertain to the physical requirements of the aerodrome itself for night operations. Similarly, while ground crew supervision can enhance safety, it is not mandated for nighttime operations. Lastly, the presence of a co-pilot may improve operational efficiency and safety but isn’t a strict requirement for taking off or landing at night.
