What is the minimum VFR flight requirement in controlled airspace at night?

The minimum VFR flight requirement in controlled airspace at night includes both vertical and horizontal visibility criteria that must be maintained to ensure safe navigation and separation from other air traffic. For night operations, a pilot must maintain a minimum of 1500 feet above the ground level and have a visibility of at least 5 kilometers. This requirement is in place to enhance safety by ensuring pilots have sufficient vertical separation from obstacles and can also adequately see and manage traffic in their vicinity.

Maintaining a minimum of 1500 feet allows pilots to avoid obstacles such as buildings, hills, and other aircraft. The 5-kilometer visibility ensures that pilots can see and avoid other aircraft, which is crucial in controlled airspace where the density of traffic can be higher at night.

Therefore, the choice that states 1500 feet and 5 kilometers aligns with the regulations for VFR flight at night, ensuring both vertical safety and sufficient horizontal visibility for operational safety in controlled airspace.
