Can planes fly at 45000 feet?
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.
Can you breathe at 40000 feet?
Somewhere between 30,000 and 40,000 feet the pressure around you becomes far too low to push those oxygen molecules across the membranes in your lungs, and you get hypoxic (altitude sickness). If you try to breathe 100 percent oxygen above 40,000 feet for very long without a special type of mask, you’ll die.
Can you fly at 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.
Why do private jets fly so high?
Private jets can fly as high as 51,000 feet. These altitudes are reserved for the larger aircraft. This is because on a short journey it is not efficient to spend significant time climbing to a high altitude, only to descend shortly after reaching the maximum altitude.
At what height do you need oxygen?
Most people will agree that supplemental oxygen should be used at the ‘Death Zone’ of 26,000 feet (8,000 meters). However, altitude sickness can set it at a much lower altitude, and depending on each individual, you should start using oxygen when you experience moderate altitude sickness.
Can a plane fly at 40000 feet?
Modern airliners are usually built with the ability to function when flying over 40,000 feet. The service ceiling is the maximum density altitude an airliner can reach according to its design. However, travelers are more likely find themselves in the air at a cruising altitude of around 35,000 feet.
How cold is it at 40000 feet?
After all, commercial airplanes can cruise at an altitude of nearly 40,000 feet, where temperatures hover around -70 degrees Fahrenheit.
Can you breathe 30000 feet?
Above 28,000 to 30,000 feet with extra oxygen under pressure — normal consciousness and life can be sustained to 50,000 feet. Yes, but only 21 percent of plain air at sea level atmospheric pressure is helping to push the oxygen into the patient’s lungs (only 21 percent of air is oxygen).
Why do airlines fly at 35, 000 feet or higher?
A continued ascend will further reduce the amount of oxygen in the air, which may reduce the power generated. A higher elevation will require a longer climb, meaning the aircraft will burn more fuel in order to reach its cruising altitude. Additionally, 35,000 feet gives more time for airline crew to address any unexpected mid-flight incidents.
Can a plane land at 43, 000 feet?
Aircraft can still land safely even if both engines fail, so this level maintains a balance of safety and efficiency. Airliners such as the Boeing 767 have the capability to reach 43,000.
What is the speed of a plane at 30000 ft?
Knots, 761 mph), a plane flying Mach 1.0 at 30000 ft is flying 1091 km/h (589 knots, 678 mph) etc. Speeds below Mach 1 are called subsonic, between Mach 0.8-1.2 Transonic and above Mach 1.2 Supersonic. ©1996-2011 Fighter Planes and Military Aircraft
What’s the highest altitude a business jet can go?
Many business jets can travel even higher, at 50,000 feet, due to having large engines for the small size of the aircraft. The lighter weight enables these aircraft to climb higher more easily than larger jets with many passengers and materials. Furthermore, Concorde could reach a maximum cruising altitude of 60,000 feet.
