Why is A350 special?
The 787 and A350 are the first large commercial aircraft to be constructed extensively from carbon fibre reinforced polymer (CFRP). CFRP is more durable as it doesn’t corrode to the same extent as traditional aluminium used in older planes, translating into lower maintenance costs for airlines.

Why do private jets fly so high?
Bottom Line. When it comes to private jet cruising altitude, private jets indeed fly higher than commercial jets. The two main reasons why they fly higher is because there’s less traffic at higher altitudes, which means they aren’t competing for the same airspace as other airplanes.
Why do commercial jets fly so high?
The reason aeroplanes fly so high is due to improved fuel efficiency. A jet engine operates more efficiently at higher altitude where the air is much thinner, allowing an aircraft to travel faster whilst at the same time, burning less fuel.
How long of a runway does a private jet need?
For every 2,000-feet of elevation, you need an increase of 1,000-feet in runway length. There are some jets that have straight wings that can accommodate 5,000-ft. runways such as the Citation V/Ultra/Encore and Falcon 50. A rule of thumb for turbo props is that they need 2,800 feet at sea level.
