When planning visual navigation routes, what NM/min is typically used?

• A. 2.0 NM/min
• B. 3.0 NM/min
• C. 3.5 NM/min
• D. 4.0 NM/min

Answer: (C)

The typical ground speed used for planning visual navigation routes is 3.5 NM/min. This figure is derived from a standard cruise speed for general aviation aircraft and provides a reasonable estimate for calculating distances over time during flight planning. When pilots plan visual navigation routes, they consider factors such as wind conditions, aircraft performance, and the expected operating environment. A speed of 3.5 NM/min strikes a balance between a realistic ground speed expectation and the need for efficient navigation without being too optimistic or cautious. This speed allows pilots to effectively estimate their arrival times and manage headings and course corrections during flight. Using an appropriate planning speed is essential for safe navigation, as it can influence fuel calculations, approach timing, and overall flight management.
