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

The correct choice indicates that the altitude range for the Foxtrot working Middle Block is between 7,000 feet and 11,999 feet Mean Sea Level (MSL). This range is specifically defined for the operational parameters of the Foxtrot block within the air traffic control system, where it is essential for managing air traffic effectively and ensuring safety.

Understanding the altitude band is crucial for pilots and air traffic controllers, as it corresponds to designated airspace designed to manage specific types of aircraft operations. In this range, aircraft can operate under certain regulations that apply specifically to the Foxtrot block, allowing for better coordination and minimizing the risk of altitude conflicts among aircraft.

The other altitude ranges do not apply to the Foxtrot working Middle Block, making this option the most accurate representation of the designated altitude limits for this specific air traffic control classification.
