Flying is indeed bad for the planet because it contributes to global warming, pollution, and leaves a huge carbon footprint. Even though aviation is not a large industry, it has large impact on the climate system.  One of the most effective ways to reduce the amount of carbon footprint is by flying less often. This means in the case where other forms of transport are available, it is not a must for an individual to fly. Instead, driving or taking the train to the destination as a preference for the majority of the people would mean airlines burn less fuel.  Technological advancement in the sector might lead to electric planes that emit less and are more fuel-efficient. However, the sector remains negligent in matters of the environment. Planes are usually flying in the stratosphere, which is the second major layer of the earth’s atmosphere. The reasons why they do this are very practical and not that difficult to understand. Why   In fact, the air resistance in the stratosphere is about half of the resistance found on the ground, which means the plane can hold airspeed at lower power settings, so not as much fuel is used. Lower power settings always equal better fuel efficiency, which is important to all airline companies. Editorial Team Earth’s Mechanical Layers (not at scale). As a general rule, fuel economy gets better with higher altitudes, so stratosphere flying can save the airlines a lot of money.

The performance of an aircraft is the product of its design capabilities in terms of aerodynamics, and environmental influences that affect these capabilities.

The way in which an airplane performs in flight is important to know in advance, since the very standards in aviation related to take-off speeds, stall speeds, manageable load, and numerous other airplane maneuvers are dependent on certain criterion to ensure safe flight. This criteria is often referred to as performance limitations. Establishing performance limitations is fundamental to the safe handling of an aircraft and is indirectly related to economic aspects of commercial aviation.

Any modification to the aircraft or a new structure being added to the airplane which, in future, would compromise the aircraft performance, is simply crossed off. To understand the relation between aircraft performance and the role of atmospheric factors, one must first understand the association of air pressure and air temperature with the density of air. In this video by Kwesi, the effect of pressurizing a parcel of air can clearly be observed. Notice how the air molecules come together at increased pressure, resulting in increased density concentration.

Conversely, when pressure is reduced the molecules move away from each other thus decreasing density. Hence, the atmospheric jet planes fly in which layer of the atmosphere it has a directly proportional relation to air density whereas; temperature is inversely proportional to the density of air.

This connection significantly governs the aircraft performance. As an airplane climbs, atmospheric pressure decreases along with air density, significantly affecting aircraft performance. Variation in temperature and pressure alter the density of air and thus affect the above stated. Consider an aircraft taking-off from an aerodrome at sea-level and climbing to attain an altitude of 10,ft. Thus, reduced atmospheric pressure decreases aircraft performance in the following ways:.

Increase in temperature of a parcel of air creates hyperactivity amongst the air molecules; the molecules are energized and thus behave in a hyper manner to utilize this extra energy.

The motion of the air molecules becomes highly erratic, and they collide with each other. These collisions expand the total volume of that specific parcel of air, thus decreasing density. If an aircraft in flight enters from a parcel of air having a temperature of 20 degree Celsius, into a parcel of air having a temperature of 40 degree Celsius while maintaining the same altitudeits performance would be significantly decreased. The increase in temperature gives way to decreased air density, which in turn affects the aircraft performance characteristics in terms of reduced lifting ability and reduced mass jet planes fly in which layer of the atmosphere it air entering the cylinders for combustion.

To counter this reduced aircraft performance, devices such as superchargers and turbochargers are used to condense the atmospheric air to its optimum density, required by the engine.

Aeroplanes fly in the layer stratosphere. The lower layer of the stratosphere has a virtual absence of absence of water vapour and constant temperature conditions,therefore,it is ideal for flying jet aircraft. views View 2 Upvoters. Dec 31,  · Commercial jets can certainly fly above or below the troposphere, but this layer of the atmosphere offers ideal flying conditions for several reasons. First, the troposphere produces minimal drag or resistance for commercial jets. If commercial jets flew below the troposphere, they would burn more fuel due to the increased drag at lower altitudes. May 15,  · Jet airplanes can fly in the upper Troposphere and in the lower Stratosphere. In the upper Troposphere and in the lower Stratosphere there is the Jet Stream which gives jet planes a .
