How far is the clearance area 5 for designated mountainous regions?

• A. 2 nm
• B. 5 nm
• C. 10 nm
• D. 15 nm

Answer: (B)

The clearance area for designated mountainous regions is set at a distance of 5 nautical miles. This distance is specified in flight safety regulations to ensure that aircraft operating in mountainous areas maintain an adequate margin for navigation and obstacle avoidance. Mountains can create significant challenges in aviation due to their height and the variable weather conditions often found in such regions. Therefore, having a defined clearance area helps in mitigating risks associated with flying in proximity to elevated terrain. The 5-nm clearance provides pilots with a buffer zone to avoid obstacles and ensures greater safety during takeoff, landing, and in-flight maneuvers around mountainous landscapes. This standard is part of broader safety regulations that emphasize the need for awareness of terrain and appropriate separation to maintain safety for both aircraft and passengers.
