Many commercial passenger aircraft fly at an altitude of about 35,000 feet. When we think about it, that’s a pretty high altitude? What’s wrong with flying a few hundred meters above the ground so that an aircraft is above all Earth Structures (for example, towers and skyscrapers)? But first of all, this altitude, which all aircraft watch, is not an arbitrarily chosen number. There are many important reasons why planes in the sky fly so high.

Fuel Efficiency Due To Air Resistance

The main reason passenger planes travel at such a high altitude is fuel efficiency.  The higher you rise above the ground, the thinner the atmosphere, and therefore, the less air resistance the plane experiences as it watches. The more molecules pass through a plane, the more energy is required for movement, the same is true in aviation and increases the cost of the flight in terms of fuel. Due to the thin air at high altitudes, commercial aircraft perform a more economical flight. That’s why 35,000 feet is called the “optimal cruising altitude.” About 35,000 feet is considered suitable for fuel efficiency, taking into account operating costs. But it should be noted that some aircraft engines also perform high in thicker air, since not all aircraft engines are of the same type and design.

Cruising High From The Sky Layer Where Weather Events Occur

Another important reason for this high commercial aircraft to watch at this height a more stable weather pattern of clouds and be and often weather-related events is of great importance in terms of comfort, they watch from the sky layer higher flight. As an airline, you do not want to provide passengers with a comfort-free service; what companies want is to provide their passengers with a flight experience that will make them feel as comfortable and safe as possible.

Distance From Surfaces Where A Possible Collision Will Occur

As a pilot, you don’t want to manoeuvre between buildings, towers and all other tall earth structures when you’re flying a plane. Passengers on this plane will not find much comfort on this flight. In order to avoid a possible accident and provide a much more comfortable flight service, pilots want to watch much higher on these structures. The reason for this situation is not just earth structures. It is also desirable to avoid colliding with a bird or a flock of birds. In history, accidents and failures caused by bird strikes have occurred due to low altitude on many take-offs and landings.

Safety Height

Let’s say you’re flying a commercial plane just a few hundred feet above the ground, and something went wrong. At this time, the aircraft began to rapidly lose altitude. As a Pilot, you think you can solve the problem on the plane, but you don’t have the time. In that case, you might think, ‘I wish I was higher up and had some time to solve the problem…’  Another reason pilots watch at this altitude is that in the event of any problems, they want to have the necessary time to solve this situation. As a result, given all these reasons, we see the advantages of high altitude in terms of Economy, Comfort and safety.
