What is the altitude range for the Foxtrot working High Block?

The correct altitude range for the Foxtrot working High Block is from 13,000' to 17,999' MSL. This range is designated for operations that require separate airspace management due to potential conflicts with other flight activities, and it specifically allows for more complex maneuvers and higher altitude operations.

Understanding the configuration of airspace is essential, as it helps define where certain operations can take place safely and effectively. This range is particularly relevant for pilots, air traffic controllers, and situational awareness in flight operations. The other options present altitude ranges that do not align with the established standards for the Foxtrot working High Block, which is aimed at accommodating the needs of higher altitude flight operations while maintaining safe separation from lower altitude activities.
