Most Dangerous Airport In The World

Tenzing Hillary Airport

Tenzing Hillary Airport, also known as Lukla Airport, is a small airport in the town of Lukla, in Khumbu, Solukhumbu District, eastern Nepal. A program titled Most Extreme Airports, broadcast on The History Channel in 2010, rated the airport as the most dangerous airport in the world.

In January 2008 the airport was renamed in honor of Sherpa Tenzing Norgay and Sir Edmund Hillary, the first people to reach the summit of Mount Everest and also to mark their efforts in the construction of this airport.

The airport is popular because Lukla is the place where most people start the climb to Mount Everest Base Camp. There are daily flights between Lukla and Kathmandu during daylight hours in good weather. Although the flying distance is short, rain commonly occurs in Lukla while the sun is shining brightly in Kathmandu. High winds, cloud cover, and changing visibility often mean flights can be delayed or the airport closed. The airport is contained within a chain link fence and patrolled by the Nepali armed police or civil police around the clock.

Facilities

The runway is 527 m  × 30 m  with a 11.7% gradient. The airport’s elevation is 2,845 m. The airport is not only used for passenger flights, as most of the roofs on the houses at Lukla have to be transported by aircraft.Aircraft can use runway 06 only for landings and runway 24 only for takeoffs. There is low prospect of a successful go-around on short final due to the terrain. There is high terrain immediately beyond the northern end of the runway and a steeply angled drop at the southern end of the runway into the valley below.

The apron has four stands and there is one helipad located 140 m  from the control tower. No landing aids are available and the only air traffic service is an Aerodrome Flight Information Service.

Tenzing Hillary Airport is the one of the most dangerous  airport in the world. since, it’s opening date  15 October 1973, many plane and  helicopter have  crashed, several hundreds of people were died in this airport during land and takeoff from airport . people are risking their life every day  in the hand of  pilot to land and takeoff properly  from this airport. people have to travel by air because there is no another means of transportation. it take huge skill and training for  pilot to land and takeoff from this airport.

Top 10 Largest Hydroelectric Power Stations

1.Three Gorges Dam :

The Three Gorges Dam is a hydroelectric dam that spans the Yangtze River by the town of Sandouping, located in Yiling District, Yichang, Hubei province, China. The Three Gorges Dam is the world’s largest power station in terms of installed capacity 22,500 MW. Except for a ship lift, the dam project was completed and fully functional as of July 4, 2012, when the last of the main water turbines in the underground plant began production. The ship lift was complete in December 2015. Each main water turbine has a capacity of 700 MW. The dam body was completed in 2006. Coupling the dam’s 32 main turbines with two smaller generators 50 MW each to power the plant itself, the total electric generating capacity of the dam is 22,500 MW.
