This article will explain some of the nuances that determine how high different airplanes fly. It will also outline the highest altitude that some popular airplanes are designed to fly. Finally, it will lay out the effect altitude has on airplane performance, as well as factors such as weather and passenger comfort that explain why pilots choose to fly at various altitudes. The biggest reason for flying at higher altitudes lies in fuel efficiency. The thin air creates less drag on the aircraft, which means the plane can use less fuel in order to maintain speed.
Examples of cruising altitude in a Sentence
When you're checking the clouds, think about coverage and altitude. If you're looking at few or scattered clouds, climbing above them might be an option, but if there's a broken layer along your route, it's probably best to stay below it. Unfortunately, the same can't be said for restricted areas and other special use airspace, but a quick check on your sectional chart or ForeFlight can clear up any questions about that. There's controlled airspace, special use airspace, and just about every kind of airspace you can think of listed on sectional charts.

How high do planes fly compared to Everest?
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.

This is also the reason why it's called "cruising" altitude, because the plane is "sailing" through the air along the path of least resistance. At or Below 3,000Remember, these VFR and IFR cruising altitudes only apply to pilots operating aircraft at more than 3,000 feet AGL (Above Ground Level). Pilots operating at or below 3,000 feet AGL may fly at other altitudes. Also, these cruising altitudes do not apply when the airplane is turning or manoeuvring while practicing flight manoeuvres such as stalls, steep turns, and other activities. 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.
I fly a Cessna 172N, which comes with a POH with lots of information. One of the more useful tables is the Cruise Performance table shown below (Figure 1). The chart gives the fuel flow rate and true airspeed for various combinations of pressure altitude, temperature, and engine percent power. Unfortunately, the table only provides data at the max gross weight of 2300 lbs. The Supplemental Airplane Flight Manual has a Cruise Performance table similar to the one provided in the original POH, but it does not include cruise airspeeds! Furthermore, I often fly around at gross weights less than 1900 lbs.
The Effect of Wind Speed on an Airplane
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.
thoughts on “Cruise Performance Charts”
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.
What is the cruising altitude of an Airbus A380?
This is one reason overloading an aircraft is a really bad thing to do. The power required to fly is disproportionate with the weight increase. That lack of oxygen can occur at higher altitudes due to a decrease in oxygen pressure, according to the FAA. As the plane ascends, the level of oxygen decreases, which can cause rapid decompression for an aircraft that is not pressurized in the same way as a commercial airplane. One reason that planes cruise above the clouds is so they can fly fast.
The proposed approach achieves a decrease in fuel consumption of 1.2% when optimizing with regard to real atmosphere. Curiously, the altitude displayed at the flight levels and on your seatback display is not the actual, true altitude above the ground. Planes flying below 18,000 feet set their altimeter to a reported pressure setting. In the flight levels, the altitude is set by reference to a standard barometric pressure of 29.92 so as to create a standard reference for all aircraft and avoid any variation. Commercial or passenger aircraft are usually designed for optimum performance around their cruise speed (VC) and cruise altitude. Factors affecting optimum cruise speed and altitude include payload, center of gravity, air temperature, and humidity.

Mac McClellan is a corporate pilot with more than 12,000 hours, and a retired aviation magazine editor living in Grand Haven, Michigan. The other day we were going to Louisville Muhammad Ali International Airport (SDF) and Fltplan.com suggested FL260 for cruise. I never expected it to work, but since it was a slightly different route, we decided to try.
Pereira flies the Embraer E190, which has a performance function as part of its Flight Management System. This feature allows pilots to "what if" various scenarios based on winds aloft, weight and balance and fuel requirements. "We're always looking to maximize the benefit of the wind," she said. The cruising phase of flight begins after an airplane levels off after a climb and remains until it initiates a descent for landing. Despite all the frightening things that can happen if a plane flies too high, flying too low can be just as dangerous.
Planes flying eastward, including northeast and southeast, will fly at odd altitudes, such as 35,000 feet. Planes flying in approximately westerly directions have to fly at even altitudes. This means that planes flying in opposite directions to each other are at least 1000 feet apart, so avoiding a possible collision and making for safer flights. Of course, turbulence still happens on airplanes, but you may be surprised to know that it happens a great deal less because of the high altitude of many commercial flights. According to The Points Guy, when planes run into air pockets and fierce winds, air traffic controllers can sometimes suggest different altitudes to avoid it. According to USA Today, flying higher can actually minimize turbulence.
