There's a lot to consider when you're picking your cruise altitude. But if you're thinking about obstacles, your plane's performance, and the weather and winds along your route, you'll have a smooth flight, and hopefully some happy passengers as well. Shown in Figure 4 is just such a table, constructed for a gross weight of 1900 lbs, and for an installed engine power of 180 hp.

So once the seatbelt signs goes off, you can relax and enjoy the flight. Another reason why planes don’t fly higher is due to the weight of the aircraft. “The more you weigh, the harder it is to get to a certain altitude,” says Jorgenson. Over 42,000 planes take flight in the U.S. every day, with 5,000 in the sky at any given time, according to the Federal Aviation Administration.
Weather and Turbulence
Since 36,000 feet is a further 7000 feet higher than the peak of Mount Everest, the air up there is pretty thin. Flying at this height also lessens the chance of a plane coming into contact with something else. But really the best advice of all is to keep reading Cruising Altitude for all the latest air travel and flying etiquette tips.
Why do planes not fly directly over the Pacific Ocean?
The benefits of flying at higher altitudes include flying over bad weather, turbulence, and getting to the destination generally faster. High altitudes are also scenic and offer passengers experiences like no other. Every airplane has its own altitude limitation, usually based on the engine powering it, and pilots have to decide what altitude is best for their mission flexoffers. This type of engine prevents these smaller planes from reaching the same altitudes as commercial aircraft.
Commercial aircraft typically fly between 31,000 and 38,000 feet about 5.9 to 7.2 miles high and usually reach their cruising altitudes in the first 10 minutes of a flight, according to Beckman. Planes can fly much higher than this altitude, but that can present safety issues. As explained earlier, the limiting factors for airplanes flying higher are restrictions on the engine and airframe. Temperature cools with altitude, and engines can only sustain negative temperatures to a certain limit before they are unable to operate.

Modern systems allow planes to pass as little as 1,000 feet above or below each other. Mark Vanhoenacker, British Airways pilot and author of Skyfaring, wrote that an airplane's altitude is "vertical wayfinding in the ocean of air." Aside from that beautiful turn of phrase, here's how that works. The Piper Cub is a light single-engine aircraft built by Piper Aircraft. It is the company’s most-produced model with more than 20,000 built between 1938 and 1947. Similar aircraft are the Aeronca Champion, Aeronca L-3, American Eagle Eaglet 31, and others. “The plane that the average guy can rent and fly, those tend to stay usually below 15,000 feet and that’s just a limit on what the plane can do,” Beckman says.
Again, airliners can generally cope with turbulence, but it is preferable to avoid it if possible. Remember, Cruising Altitudes are based on your course or ground track, and the pilot must consider cross-wind variances to their heading being flown. To put that in perspective, the peak of Mount Everest measures at 29,029 feet. No matter their views on the armrest issue specifically, everyone I spoke to for this column agreed that being a decent seat neighbor is all that matters when flying. Gregg, an automation technician from Lawrence, Kansas, flies about twice a week and said he’ll often switch his flight if there are only middle seats available. However, if he has no other choice, he expects access to both armrests.
How Low Can planes fly over my house?
Example IFR Cruising altitudes would be 4,000 feet, 6,000 feet, 8,000 feet etc. East is OddAs a memory aid, I always think of people from out east speaking with an ‘Odd’ accent. East directions, from 0 degrees through 179 degrees represented on the right (or east) side of the diagram therefore use ODD 1,000 foot altitudes plus 500 feet. Conversely, the West directions, from 180 degrees through 359 degrees on the left (or west) side of the diagram use EVEN 1,000 foot altitudes plus 500 feet.
Choppers are mainly designed to fly short distances and typically fly much lower than airplanes, normally at under 10,000 feet. They are also unable to ascend to the same height an airplane can because instead of wings, helicopters fly by rotating blades. Flying higher means it would take a longer time to return to a safe altitude in case of an emergency, like rapid decompression, Beckman says. It also isn’t the most efficient use of fuel to fly that high in the first place, he says, since planes can fly at a lower altitude with the assistance of wind. You fasten your seat belt, listen to the pre-flight safety demonstration (we hope), and prepare yourself for takeoff.
Generally, the higher an aircraft gets, the less fuel it is required to use, as the air at higher altitudes is less dense, therefore, creating less drag. However, some airplanes are more fuel efficient than others, especially based on the type of engine they have. So some airplanes, such as those with piston engines, can only fly at lower maximum altitudes. Meanwhile, turboprops and turbine engines allow other airplanes to fly higher.
Planes flying in the North Pole, thus, need to have equipment that can compensate for this as best as possible. “This is what you get when you poll 1,000 people,” he said, nodding to how little common ground we have on some things. But, according to Kayak’s survey, only 43% of air travelers agree with me.
It is probably not really safe for them to be much above 10,000 feet. And a substantial majority of small planes are flown for recreational purposes, and pilots enjoy flying lower, where they can see things below them. However, a plane’s engines need oxygen in order to function, so flying too high can also cause problems. Plus if a plane goes higher, it has to burn more fuel in order to get there.
What will be the impact on airspeed and fuel consumption with the higher horsepower engine at reduced gross weights? In this post, I show how to make cruise performance charts for any weight or altitude, and how to estimate the performance of the modified aircraft with the 180 hp engine. This paper considers subsonic turbojet aircraft fuel consumption minimization problem during cruise phase, assuming fixed time of arrival. We utilize tailwind/headwind component values at various flight levels, as well as air temperatures and atmospheric pressures at various altitudes. The solution to the altitude and speed flight profile optimization problem is through constrained coordinate descent method. The paper considers optimizing the fuel consumption of a medium-haul aircraft during the cruise phase using sample data set on temperature, pressure, and wind speed.
