What is the maximum flight level of a 747?
What is the maximum flight level of a 747? Boeing widebodies The German flag carrier also flies the modern 747-8, which has a service ceiling of 43,100 ft (13,137 m).
Why do planes fly at 41000 feet?
The biggest reason for flying at higher altitudes lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed. Less wind resistance, more power, less effort, so to speak.
How high can you fly before needing oxygen?
Most pilots don't think too much about using portable oxygen. Sure, everyone knows that you have to use supplemental oxygen if you fly more than 30 minutes at cabin pressure altitudes of 12,500 feet or higher. And that at cabin altitudes above 14,000 feet pilots must use oxygen at all times.
Why planes don t fly over Tibet?
The mountainous region of Tibet increases the risk of turbulence, making it disruptive for passengers and potentially dangerous. Low temperatures in the region pose a risk of jet fuel freezing, which can lead to severe crashes, highlighting the importance of temperature for jet fuel flow.
Can planes fly over Mount Everest?
Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.
How high can a A380 fly?
The Airbus A380, for example, is 43,100 feet and the A350 and Boeing 787 are the same (although the larger 787-10 and A350-1000 are lower at 41,100 feet and 41,450 feet). The A380 has a ceiling of 43,100 feet. Photo: Curimedia Photography via Wikimedia Commons.
How high is the flight deck of a 747?
The pilot's eye level on the flight deck of a 747 is just a little more than 8 meters (26 feet) above the ground.
Why don t planes fly over the Black Sea?
Large part of the Black Sea is considered a risk area as well, due to Russian fleet operations. Furthermore, due to sanctions, western airlines do not fly through Russian airspace.
What is the highest elevation a jet can operate?
The maximum height that a commercial airplane is allowed to reach when they fly is 42,000 feet, as this is the universally approved maximum altitude. This max altitude for airplanes is known as the “service ceiling.” Most commercial air jets fly at such a high altitude because it is known to optimize efficiency.
What is the takeoff speed of a 747?
A typical takeoff speed for a Boeing 747 is around 160 knots (184 mph), depending on the jet's wing flap configuration, the number of passengers aboard, and the weight of their luggage, fuel load, current weather conditions, and other factors.
Is flying over the ocean safer than flying over land?
When flying over land, of course it is more likely that there will be more airfields closer to the aircraft at any given time. However, because of lessons learned from its history and the improvements in aircraft and engine reliability, crossing the oceans is deemed as safe as flying over land.
How long does pilot oxygen last?
If anything happens to the pressurization system, or the plane experiences any difficulties while in flight, oxygen masks will deploy. Oxygen masks supply roughly 10-14 minutes of oxygen, which is more than enough time for a pilot to descend below 10,000 feet, where the atmosphere has enough oxygen.
What is the maximum altitude a 747 can fly?
Different airplanes have different maximum altitudes, depending on their construction. For example, the Airbus A320 has a maximum altitude of 39,000 feet (11,900m) and the Boeing 747 45,000 feet (13,700m).
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.
What is the longest overwater flight?
The longest over water route in the world is the stretch between the U.S. mainland and Hawaii. Even between Hawaii and Tokyo there are alternate airports available, such as Midway Island (hence the name “Midway”). Going across the North Atlantic, alternates include Iceland and Greenland.
Why flights don t fly over Pacific Ocean?
Most flights are intended to spend as little time as possible over water, since storms are more common over the ocean than on land. An aircraft would not be safe to fly over the Pacific Ocean due to the stormy weather and frequent lightning strikes that occur there.
Does anything 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).
How high can a Boeing 787 fly?
' For example, for the double-decker Airbus A380' superjumbo' quadjet, the service ceiling is 43,000 feet. Meanwhile, for the Boeing 787-8 and -9 'Dreamliner,' it is 43,100 feet. However, the stretched-fuselage 787-10 comes in a little lower, at 41,100 feet. Want answers to more key questions in aviation?
