What is considered high altitude for flying?
What is considered high altitude for flying? From a practical point of view, 'high altitude' operations are taken to be those above FL250, which is the altitude at above which aircraft certification requires that a passenger cabin overhead panel oxygen mask drop-down system has to be installed.
Is there oxygen at 35000 feet?
Planes have lower oxygen levels If this didn't happen, everyone inside the plane would die, as the low air pressure at the elevations planes fly (typically 35,000 feet or so) means there isn't enough oxygen present for your body to function.
What ocean can you not fly over?
Jet streams, which are a system of air currents that circle the Earth many miles above the planet's surface, are another reason why aircraft don't fly over the Pacific Ocean. Due to Earth's rotation, these air currents often move from West to East.
What is a safe altitude for planes?
One thing that pilots and prospective aircraft dispatchers need to understand is that there is not one universal safe altitude since some terrains or objects may be taller than others. Rather, the accepted metric is that this altitude needs to be at least 500 feet above the terrain or obstacle in question.
At what altitude does hypoxia start?
In aeronautics, hypoxia typically results from a decompression or lack of pressurisation of the aircraft cabin. Hypoxia occurs within a few minutes if the cabin pressure altitude rises to between 5,000-6,000 m (about 16,000 - 20,000 ft).
Why do 99% of planes not fly over Pacific Ocean?
Because of its vast size, crossing the Pacific Ocean requires a staggering quantity of fuel. However, most commercial aircraft do not fly directly over the Pacific Ocean; instead, they choose what are known as 'curved paths'. These paths offers a faster, more efficient route given the curved nature of the earth.
Can a plane fly at 60000 feet?
There are no specific regulations governing civil aircraft operations beyond the altitude of 60,000 feet. Nevertheless, certain exceptional aircraft like the Concorde and the Tupolev Tu-144 have managed to ascend to altitudes of FL600 (equivalent to 60,000 feet).
What is the longest flight in the world?
What is the longest flight in the world by distance? The longest flight in the world by distance is New York (JFK) to Singapore (SIN) on Singapore Airlines clocking in at 9,537 miles. What plane can fly the farthest in the world?
Can planes stop in air?
Aircraft with fixed wings cannot stand still in the air, unless we are talking about VTOL (Vertical Take Off and Landing) aircraft. Lift is created by air flowing around the wing. Too little forward speed, and the wing will stall (loose lift).
