Low Visibility Procedures are primarily required for what types of operations at an aerodrome?

Low Visibility Procedures (LVP) at an aerodrome are instituted primarily to enhance safety during operations when visibility is significantly reduced. The key requirement for implementing these procedures is based on the visibility or Runway Visual Range (RVR) conditions.

When visibility or RVR drops below 1500 meters, the risk associated with aircraft operations increases, necessitating the introduction of specific protocols to manage takeoffs and landings. This includes ensuring that pilots have the necessary information regarding runway conditions, as well as having ground control procedures in place to avoid accidents during critical phases of flight.

While precision approaches, such as Category II and III approaches, are designed to operate safely in low visibility, they are not the sole focus of LVP. Instead, Low Visibility Procedures encompass a broader spectrum of operations, including all approaches when visibility conditions dip below the threshold of 1500 meters. This approach includes ensuring that all aircraft can safely manage landing and takeoff in reduced visibility conditions, not limited solely to precision approaches or categories.

Therefore, the correct option encompasses a wider range of operations, emphasizing the critical threshold of visibility limits that trigger Low Visibility Procedures for all approaches, not just specific ones like Category II and III.
