Question:
Is it really nessecary for airplanes to fly 30000 and higher altiutudes?
Answers:
Has anyone heard about the Airbus A380 having structural failure allready?
The air is thinner. hence the flight will be smoother. A lot of times, the low altitude flights are bumpy...Some planes are up there to track, so they need to be high as possible to get the photos needed.Does United's 747-400 have IFE on International Flights to Shanghai?
so people don't look into the windowsI think the reason is planes can go faster at high altitudes due to the air been thinner. I think its called the slipstrem
Jet engines are DESIGNED to fly at high altitudes. They get better economy. A jet aircraft needs to get altitude as quickly as possible. And second, the air is less turbulent and therefore a smoother ride. Pops
The air is much thinner at high altitudes, and the engines on long-range jets are designed to operate at their best efficency in thin air. Also, since the air is so much thinner at high altitude the resistance against the aircraft (drag) is much reduced, meaning they jet burns less fuel for the same effect. This translates into much better fuel economy, leaving more money per mile for the airline. Also, airliners cruise at different altitudes with a minimum 500' of separation. This makes for a lot of different "lanes" for them to use, and makes it safer for many planes to be in the air at the same time, reducing the chance of collision.
What do I do if I loose my Pilots License and Logbook?
Number one, the higher you go, the smoother the air is. It is also because the higher you go, you cover more distance because the arc of assent and descent covers greater distance. There is less structural stress on an airplane at a higher altitude. The temperature is very cold, so jet engines perform better and more efficiently. Finally, the higher you go, the less congested the air space is.where can i get the best deals on flights?
At higher altitude the air is thinner and there is less drag on the airframe, the engines also consume vastly less fuel. As the air gets colder the engines run more efficiently until you get to about 36,000 feet where the air stops cooling down. There's also a change over between your ground speed being limited by indicated air speed and mach number. Below that height, somewhere around 28,000 feet, as you climb at constant air speed your ground speed inscrease, above that height as you climb at constant mach number your ground speed decreases... and so does your indicated air speed which ultimately limits your altitude as your indicated air speed at maximum mach number starts to approach your minimum air speed without high lift devices.The Sky Car by Moller. What do u think about it?
Passanger comfort and avoiding weather are important, but efficiency is king, that's why 747s were capable of M0.92 but more modern jets tend to cruise at M0.8 and max out at M0.875 or below. They can't back off the mach number much without reducing their ability to reach the most effieient cruising altitudes.
How many people died in airplane accidents?
less turbluence, smoother, above all the clouds and storms.What are some great schools for getting your pilots license for helicopters and airplanes?
The primary reason is to fly above the weather that would be encountered en route at lower levels. Passenger comfort, safety, separation from other aircraft, & depending on direction of flight, to take advantage of the higher wind speeds that are available at the higher altitudes.how fast is the speed for landing on a military jet?
two reasons:1) better fuel economy
2) higher airspeed
How Hard is it to get a private pilot certificate?
As a space shuttle pilot, I personally think that airplanes fly pretty darned low! Just kidding. Yeah, it's all about smooth air and the fact that jet engines operate much more efficiently at high altitudes where the air is thinner.How do you think airline transportation has changed the past 50 years?
Aircraft need at least 1,000 feet separation to keep them from a risk of collision. Also, at high altitudes, aircraft can avoid bad weather from below (e.g. storms).How often must I retrain to keep my Red Wings and Inverted Brown Wings current?
yeah, the air is thinner up there so there is less air resistence and the plane is more fuel efficiantMore Questions & Answers ...
