What is the approach speed range for category B aircraft?

The approach speed range for category B aircraft is defined by their typical landing speeds, specifically ranging from 91 to 120 knots. This categorization is important in aviation, particularly for the purposes of determining the needed separation between different aircraft during approach and landing phases, as well as for setting appropriate airspace management policies.

The specific speeds in this range reflect the expected operational capabilities of aircraft classified under category B, which typically includes small turboprop and business jets. Understanding this speed range helps pilots and air traffic controllers make informed decisions regarding safe operations in shared airspace, especially in busy terminal environments where multiple aircraft are operating simultaneously.

The other options listed either define incorrect ranges for category B or refer to speeds that are characteristic of other aircraft categories. Therefore, the range of 91 to 120 knots is an essential benchmark for identifying approach speeds suitable for aircraft in this classification.
