Final answer:
A High Minimum Captain requires higher approach minimums for landing than standard operations due to factors like experience or recent flight performance. These elevated minimums provide a larger safety buffer for approaches in challenging conditions. The exact minimums are defined by the airline and comply with aviation regulations.
Step-by-step explanation:
A High Minimum Captain refers to a captain who requires higher minimums for approach and landing than what is prescribed for standard operations. This can occur due to various operational restrictions possibly related to the captain's experience, recent incidents, or recency of flight experience.
The approach minimums for a High Minimum Captain are greater than those for other captains. This safety margin is tailored to account for the individual circumstances of the captain, which can include limited experience in certain conditions, training requirements, or recent flight performance. These enhanced minimums ensure that the captain has a larger buffer of safety when conducting approaches, particularly in challenging weather or airport environments.
For example, if standard approach minimums for an airport are 200 feet above ground level (AGL) for decision height (DH) and half a mile for visibility, a High Minimum Captain might be restricted to a minimum of 300 feet AGL for DH and one mile of visibility. The exact enhanced minimums a High Minimum Captain must adhere to can vary and are typically outlined by their employer, such as the airline, and are in compliance with aviation regulations.
