In designated mountainous region clearance area, what altitude is typically recommended?

• A. 500 ft
• B. 2000 ft
• C. 1000 ft
• D. 1500 ft

Answer: (B)

In designated mountainous regions, it is generally recommended to maintain a clearance altitude of 2000 feet above the highest obstacle within a specified horizontal distance. This recommendation is based on the increased risk of terrain encounters in mountainous areas, where elevations can vary significantly and unexpectedly due to the topography. By maintaining this altitude, pilots ensure a safer margin of separation from potential obstacles such as ridges, peaks, and other elevated terrain features. The specified clearance altitude is designed to provide a buffer that accommodates for variations in terrain and, in the event of unexpected weather conditions or navigational errors, allows for adequate reaction time. Many aviation regulations and safety practices emphasize the importance of maintaining higher clearance in these challenging environments to mitigate risks associated with flight operations.
