What is the temperature at 36000 feet?
For example: at 36,000 feet the standard outside air temperature is -56.5°C (-69.7°F) and is well below Jet-A’s freezing point of -40°C/F.
What is the temperature at 30000 feet above sea level?
A: The standard temperature for 30,000 feet is -44.5C or -48F (Source: meteorologytraining.tpub.com/14269/css/14269_75.htm). All materials used in airplanes are designed and tested to withstand temperature extremes.
How do you calculate temperature above sea level?
NASA supplies a formula that calculates the expected stratospheric temperature (T in degrees C) given the global average temperature of -57 degrees C at 25 km altitude. The formula is T = -131 + (0.003 * altitude in meters).
What is the cruising altitude of a plane during a flight?
Specific to your question, the “cruising altitude” for most long-distance flights is somewhere between FL200 an FL300 (20,000 to 30,000 feet above sea level) To answer this question, let’s first examine a standard atmosphere.
How fast can a plane fly at sea level?
at that altitude). A plane flying Mach 1.0 at sea level is flying about 1225 km/h (661 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 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 is the temperature outside a plane at 35000 feet?
The International Standard Temperature (ISA) at 35,000′ is approximately -55 degrees C. — what is the temperature outside a plane at 35,000 feet? Most performance and flight planning graphs and tables use either degrees Celsius or Fahrenheit or both. The Kelvin scale, however, is used for Mach number calculations.
