Why do planes fly at an altitude of 35,000 feet?

If you travel a lot in airplanes, shortly after takeoff, the pilot usually announces that the plane is flying at 30,000 feet or above.

Airplanes usually fly at an altitude of 30,000 to 42,000 feet. But the question is why planes travel at such high altitude?

The answer is not simple, but a number of factors play a role, especially fast travel and planes become easier to secure.

Yes, the higher altitudes planes travel, the less dense the surrounding air is, which helps planes travel at higher speeds. Thus, fuel is also consumed less while maintaining the desired speed becomes easier.

Airplanes can travel at higher altitudes, but then the risk of various problems increases. Higher altitude means longer time to return to safe altitude in case of emergency, while too high altitude does not save fuel.

One of the reasons for flying at an altitude of 30,000 to 42,000 feet is that it helps the aircraft avoid various meteorological problems during flight.

It should be noted that at 30,000 feet or above, it is not possible to breathe without an oxygen mask and that is why aircraft cabins are specially pressurized so that passengers and crew can breathe normally.

According to experts, the altitude of a flight is determined by factors such as the model of the aircraft, its weight, weather conditions, air traffic and direction of flight.

The main reason for flying at this altitude is to ensure the safety of the aircraft and passengers and to save fuel, as birds or buildings are not encountered at this altitude.
