How high does the average plane fly?

Answer 1

Every model of aircraft is different. It depends on the pressurization of the aircraft. Some aircraft provide as little as 3psi of pressurization, which only allows for flight at 20,000ft.
If the aircraft isnt pressurized at all, then they are only allowed to fly at 14000ft without providing the crew with supplemental oxygen.
Some small aircraft that are turbocharged can cruise at up to 25,000ft, but still require supplemental oxygen.
Most jets have a significant amount of pressurization, which allows them to operate at near 50,000ft, but some cannot.
Many regional jets only have 5-7 psi of pressurization, so they are limited to less than 30,000ft.
Besides the actual capability of the aircraft, the flight plan decides the flight level. Chances are that the altitude has much more to do with the actual route than the aircraft itself.

Answer 2

There is no such thing as an "average" plane. If you want to narrow down the classification to one type, you can get an answer.
There are planes that fly a few hundred feet off the ground and there are planes that fly many thousands of feet off the ground.

Answer 3

Airplanes are divided into performance classes. Each
class has progressively better performance. Reciprocating
(car-type) engines can go up to 14000' (give or take a little),
turbocharged recips can get to about 26000', turbo props
(jet engine with a propeller attached) go to about 32000 and
jets can get up to about 51000' (non-military). Not all of each
class can go to the top for their class and there are other
factors that affect their best altitude. These are just "ball
park" numbers so as not to overload you with information.

Answer 4

Avg Passenger Jets fly around 30,000 feet ASL (Above Sea Level). Prop jobs are a different story.

Answer 5

Pressurized airliners, on domestic or regional, fly between 18,000 to 30,000 ft (although some airplanes themselves are rated to go as high as 40,000 ft)

Those on long international routes, they make advantage of the fuel economy on higher altitudes, so they fly bet. 35K to 42K ft.

Answer 6

A commercial passenger jet cruises at 29,000', 31,000', 33,000', 35,000', 37,000', 39,000' and 41,000 feet.

There is no such cruise altitude of 30,000'. For separation purposes, that is not a legal altitude for an aircraft.

Answer 7

most commercial jet's fly within 30,000, most long and medium haul flights will cruise at 36, 37 or 38,000 ft and short haul lower, maybe 32 or 33,000 ft.

Answer 8

light aircraft 2000 feet
Comercial jet 30000 feet

Answer 9

30,000 feet
