Why do commercial planes fly at 35000 feet?
A balance between operating costs and fuel efficiency is achieved somewhere around 35,000 feet, which is why commercial airplanes usually fly at that altitude. Commercial airplanes can climb to 42,000 feet, but going beyond that can be precarious, as the air starts to become too thin for optimum flight of the airplane.
What is the highest altitude a commercial airplane can fly?
Question: What is the highest altitude an airplane can fly? Answer: The highest commercial airliner altitude was 60,000 feet by Concorde. The highest military air-breathing engine airplane was the SR-71 — about 90,000 feet. The highest airliner flying today reaches 45,000 feet.
How high does a 747 cruise?
35,105 ft
Every flight has its own ideal cruising altitude. This is the sweet spot where plane fly as fast as possible, but burn the least amount of fuel. A Boeing 747 has a cross height of 35,105 ft, while the Embraer climbs 190 to 39,370 ft. The Airbus A380 can even fly at 43,097 ft.
Why do commercial airplanes fly at 30000 feet?
Most often, commercial airplanes fly anywhere between 30,000 and 42,000 feet in the air, which equals five to seven miles high. Why? The main reason is fuel efficiency. Put simply, airplanes use less fuel in higher altitudes where the air is thinner, increasing the efficiency and saving them money at the same time.
What happens if a jet flies too high?
When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …
Can a plane fly 50000 feet?
Answer: Every airplane has a certified maximum altitude. A: Yes, very high altitude, above 50,000 feet, where there is very little air, has little or no turbulence.
What is the cruising altitude of a 777?
35,000 ft

Do planes fly over Mount Everest?
Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.
What is the average altitude of a commercial airplane?
According to USA Today, the common cruising altitude for most commercial airplanes is between 33,000 and 42,000 feet, or between about six and nearly eight miles above sea level. Typically, aircraft fly around 35,000 or 36,000 feet in the air. To put that in perspective, the peak of Mount Everest measures at 29,029 feet.
What are the different cruising altitudes in aviation?
Hemispherical Cruising Altitudes – VFR and IFR Cruising Altitudes. 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.
What is the minimum AGL required for cruising altitude?
3,000 AGL. Designated Cruising Altitudes are required for flights operating at more than 3,000 feet Above Ground Level (AGL). When a pilot is operating at more than 3,000 feet above the surface, they are to fly at an altitude appropriate for their direction of flight.
What is the cruising altitude of an IFR aircraft?
Example IFR Cruising altitudes would be 4,000 feet, 6,000 feet, 8,000 feet etc. Remember, Cruising Altitudes are based on your course or ground track, and the pilot must consider cross-wind variances to their heading being flown.
