When you check Flightradar24 and focus on the Himalayas region, you’ll notice a ‘hole’ or an area where very few planes fly above. Is this some sort of ‘no-fly zone’? Not exactly, but it’s more about commercial airlines avoiding flying over the Himalayan mountain range, which includes the world’s highest peak, Mt. Everest. So, are there any ‘supernatural’ reasons for this avoidance? Actually, it’s primarily for safety reasons that planes avoid flying over the Himalayas region.
Flying over the Himalayas, home to the world’s tallest mountains including Mount Everest, presents unique challenges for aviation. The sheer height of these mountains, with many peaks soaring over 8,000 meters, poses a significant risk. Commercial flights typically cruise at altitudes between 33,000 and 42,000 feet, but to safely clear the Himalayas, they would need to ascend even higher, entering a zone fraught with dangers.
The Himalayan region is notorious for its harsh weather conditions, characterized by high winds and low temperatures, which can impede a plane’s ability to gain necessary lift. Additionally, the thin air at these extreme altitudes strains the engines and complicates maintaining cabin pressure. Low oxygen levels in the stratosphere increase the likelihood of encountering clear-air turbulence, a leading cause of in-flight injuries due to its near invisibility on radar.
Safety and Practicality
While technically feasible for some planes to fly over the Himalayas, most commercial airlines avoid this route. The risks, including potential cabin depressurization and the challenges posed by low oxygen levels, outweigh the benefits. In the event of cabin depressurization, pilots must descend to safer altitudes, typically around 10,000 feet, to ensure passengers can breathe without oxygen masks. Over the Himalayas, descending to such altitudes is not feasible due to the high elevation of the terrain.
In case of emergencies, the Himalayas offer limited options for safe landings due to the rugged terrain and scarcity of flat surfaces. This limitation significantly reduces the pilots’ ability to respond effectively to in-flight crises, further discouraging airlines from choosing routes over this mountain range.
Exceptions and Military Presence
While long-haul international flights generally avoid the Himalayas, regional flights, such as those to cities like Kathmandu and Lhasa, do operate within the mountainous area. These flights are typically shorter and cater to the specific needs of the region. Additionally, the Himalayas are a strategic location for military and surveillance operations, especially along the borders of India and China. This military activity is another reason commercial airlines prefer to steer clear of the area to avoid potential conflicts or airspace restrictions.
The decision to avoid flying over the Himalayas is rooted in prioritizing passenger safety and aircraft integrity. The combination of extreme altitudes, challenging weather conditions, and limited emergency response options makes it a less desirable route for commercial airlines.
