Why do private jets fly at 45000 ft?

Simply put, the private jet is at a higher altitude, so there will be more time to get from where it is in the sky back to the ground. This extra bit of altitude means the pilot can safely determine where the emergency landing will need to take place and in a timely fashion.

Although private jets tend to cruise at an altitude of 41,000 feet, they have the capability of reaching heights of 45,000 feet. Altitudes higher than this tend to be reserved for military aircraft that comfortably reach an altitude of up to 51,000 feet.

Another tremendous private jet option, the Gulfstream G650ER, has a 7,500-mile range and allows for 14 hours of flying before needing to stop and refuel. It is the extended-range version of the Gulfstream G650, which is another great option but offers a lower range of about 7,000 miles.

It is powered by two engines and is the largest twin jet aircraft. The Boeing 777 is certified to fly as high as 43,100 feet, but typically cruises between 35,000-39,000 feet.

Planes are *optimized* to fly at certain heights to maximize the efficiency of their engines and their fuel consumption. So jet planes can fly a lot higher than propeller planes, so they do. They fly between 20,000 feet and 40,000 feet because they are designed and optimized to do just that.

Flying at 45,000 feet plus altitude might avoid traffic and weather, but it also comes with its own risks. For example, if the aircraft was to rapidly depressurize and emergency oxygen fail, the time of useful consciousness at 45,000 feet is just nine to 15 seconds.

Do private jets experience more turbulence than commercial airliners? Private jets are smaller and lighter than commercial airlines and hence are more susceptible to turbulence.

To maintain their operational ceiling of 70,000 feet (21,000 m), the early U-2A and U-2C models had to fly very near their never-exceed speed (VNE). The margin between that maximum speed and the stall speed at that altitude was only 10 knots (12 mph; 19 km/h).

Although there are a lot of variables to account for, generally speaking, a private jet with 8-10 passengers can travel at speeds between 780 and 930 km/h. – Private long-distance planes (with 10-16 passengers) often travel at a speed of 850-1,100 km/h.

Under Part 117, the part of the federal law that covers flight duty limitations and rest requirements for airline pilots, pilots are limited to 100 hours per month and 1,000 hours per year, in addition to daily restrictions.

They're not glamorous, but they're very comfortable, with padded bunks and sometimes even in-flight entertainment! With 14- to 18-hour flights no longer unusual, pilots and cabin crew have legally mandated rest times —and airlines also realise that a rested, refreshed crew member is a happy crew member.
