Why can a cessna fly at very high altitudes as the boiengs and airbuses do ?

Question

And why ?

Answer 1

Cessna makes jets that fly as high as other jetliners. I'm not sure if I quite understand your question. The previous answers are mostly right. Piston driven propeller planes cannot fly much over 14000' because of air density required for combustion. Turbochargers and superchargers can boost their performance quite a bit, but not up to 30000'. There are of course exceptions, but not in your typical production piston prop plane.

Answer 2

Depends on which cessna your talking about. Piston engines can only fly so high principly because of their design. They need oxygen and a certain amount of pressure to run. The cessna jets like the citation can fly as high or higher than the big boys (737, 777, A320, etc.) due to wing/engine/fuselage design and also because the people who own those types of things are more interested in getting from place to place and not as interested in fuel performance. After about 36,000 feet jet engine performance drops off considerably.

Answer 3

I think you mean why CANT. At higher elevations the air is thinner and a Cessna 150, 172, etc. is incapable of the airspeed to generate sufficient lift. Also the air above 10000 feet or so is to thin and cold and planes need heated, pressurized cabins at higher altitudes.

Answer 4

Cessna builds business jets, including (the last I knew) the fastest business jet in the world. These jets normally fly well above the airliners, in the 41 to 45 thousand foot levels. Being able to attain these altitudes is a function of thrust to weight and sealing as well as structural strength of the pressure vessel (the cabin).

Answer 5

The simple answer is: Most Cessna jets are certified to fly up there with the big boys, and some are certified to fly even higher, up to 51.000 feet.

Answer 6

cessna cant fly at high altitudes like boeings and airbuses. for one the cabin inside a cessna is not pressurized. and the windows are square. a high flying jet will never have square windows. it gives a pressure point. also cessnas are propeller driven, with exception of cessna citation. air is to dense for the engine to take in air and for prop to push air.

Answer 7

Cessna makes quite a few different models, from relatively low performance single engines (150, 172) through pressurized/turbocharged twins (340, 421), turboprops (425, 441) and a number of jets (various models of the Citation, including the Citation X (Ten), which typically cruises at higher altitudes than any airliner. Actually, a Cessna Turbo 210, a turbocharged high performance single engine propeller-driven airplane, held the altitude record for its class for over 20 years (and may still hold that record) at over 43,000 feet. Most of the "low performance" single engine Cessnas are capable of flight at 12,000 - 15,000 feet, medium performance (182, 206, 210, etc.) can climb to around 16,000 - 18,000 feet, but are typically flown at altitudes below 12,500 feet. High performance turbocharged singles, such as the Turbo 210, can climb and cruise at altitudes typically up to around 30,000 feet (although later models of the T-210 and all the P-210s - pressurized and turbocharged single engines) are limited to 25,000 feet by their certification - they are physically capable of higher altitudes, but are legally limited to that altitude by their FAA type certificates, while earlier models are free of that limitation). Most normally aspirated (non-turbocharged) Cessna twin-engine propeller-driven aircraft are capable of cruising at over 20,000 feet (I have done this quite a few times in my normally aspirated Cessna 310s), and the turbocharged piston engine twins are capable of much higher altitudes (I used to own a Turbo 310, which was quite happy at altitudes up to 30,000 feet). The late model pressurized and turbocharged twins are limited to 25,000 feet by their type certificates, with some consideration to the pressure differential they are capable of maintaining (the non-pressurized turbo'ed twins are not limited, as the built-in oxygen systems, using oxygen masks, provide adequate breathing oxygen to the pilots at higher altitudes). The turboprops (425, 441) and jets (Citation series) are designed to fly at high altitudes, due to increased efficiency in those regimes. Basically, that summarizes the physical limitations response to your question.

Now, if you are asking this question in regard to legality, the airspace belongs to everybody, and it is entirely legal for any pilot with appropriate certifications and ratings, as well as an aircraft with the performance and equipment required to fly at high altitudes, to fly there. In the continental U.S., all airspace above 18,000 feet is positive controlled airspace (the old designation, now its "Class A airspace," which doesn't really describe it), requiring an IFR clearance to operate at altitudes of 18,000 feet and above; also, above 24,000 feet, the aircraft must be equipped with an operating DME. The National Airspace System and the Air Traffic Control System, although designed with a heavy emphasis towards handling airline traffic, was designed and is operated (navaids, ATC, etc.) with government funds, and has a similar function to the Interstate Highway System. To try to exclude private aircraft from any segments of it would be akin to restricting private cars from using the highways, allowing only trucks and busses on them.

Answer 8

Citation jets are Cessnas and they can and do fly higher than airliners. Manufacturer has nothing to do with it.

Answer 9

Don't understand your question ! Are you asking whether a Cessna can fly to thos heights or are you asking why it cannot.
However a Cessna does not have the thrust required to take it over 30000 feet which the height at which jets fly. Some fighter aircraft can go upto over 50000 feet.
Cessna's or most turb props cannot go beyond 10000 feet.

Answer 10

No a Cessna is not pressurized, at over 13,500 humans have breathing issues & it a propeller drivin so you have a limit on air dencity at higher altatudes, The engine has breathing issues too, thats why they put turbo and super chargers on piston engines. that doesn't effect a jet as much.
