What altitude should Fist 304 be at given its position and established conditions?

The correct altitude for Fist 304, given its position and established conditions, is at Angels 1.2, which translates to 12,000 feet. This altitude is typically determined based on various factors, such as air traffic control procedures, the specific route being flown, and current air traffic around the aircraft.

In this situation, Angels 1.2 is appropriate as it often aligns with safe vertical separation from other aircraft, ensuring that Fist 304 can navigate efficiently without conflicting with nearby traffic. This altitude choice also suggests that the aircraft is gaining altitude adequately and is likely at a stage in its flight where it is transitioning to cruise altitude. Knowing that "Angels" refers to thousands of feet is essential for understanding the options, and selecting 1.2 demonstrates an understanding of airspace management and safety protocols at that altitude.

In contrast, other altitude options such as Angels 1.0 or Angels 1.5 may not optimize aircraft separation or could lead to potential airspace conflicts in that particular flight scenario.
