When you are flying in an airplane you might be at an altitude of?
Commercial aircraft typically fly between 31,000 and 38,000 feet — about 5.9 to 7.2 miles — high and usually reach their cruising altitudes in the first 10 minutes of a flight, according to Beckman. Planes can fly much higher than this altitude, but that can present safety issues.
How do you calculate airport pressure altitude?
Find pressure altitude
- Subtract the current altimeter setting from the standard pressure of 29.92.
- Multiply by 1,000.
- If you have a negative number, subtract it from the field elevation. Add a positive number.
What part of the atmosphere would you be in if you were flying in a plane?
stratosphere
Planes are usually flying in the stratosphere, which is the second major layer of the earth’s atmosphere.
How do you find the maximum forward speed of a level flight?
Altitude-Speed Cross plots The intersection of the thrust (thrust available) curve with the drag (thrust required) curve is the solution to Eq. (1), T = D. Consequently these points represent the maximum speed that the aircraft can fly at each altitude for the given weight and throttle setting.
How do you calculate true altitude?
The formula to find height above a ridge is as follows: ((Indicated Alt – Ground Elevation) / 1000) X Difference between ICAO and actual temp X 4 = amount to be subtracted from indicated altitude. This gives true altitude. Take your true altitude, subtract it from the height of the ridge and you have your clearance.
Do planes fly above the troposphere?
Although there are exceptions, most commercial jets fly at around 28,000 to 35,000 feet. Commercial jets can certainly fly above or below the troposphere, but this layer of the atmosphere offers ideal flying conditions for several reasons.
What is maximum level flight speed?
The maximum level flight speed for the aircraft is obtained when the power or thrust required equals the maximum power or thrust available from the powerplant.
What is the air pressure of an airplane at sea level?
The air pressure is computed assuming an International Standard Atmosphere pressure of 1013.25 hPa (29.92 inHg) at sea level, and therefore is not necessarily the same as the aircraft’s actual altitude, either above sea level or above ground level .
How do you calculate altitude from air pressure and temperature?
Due to the fact that weather conditions affect pressure and altitude calculations, the pressure and temperature at sea level must be known. The altitude at a given air pressure can be calculated using Equation 1 for an altitude up to 11 km (36,090 feet).
What is the normal altimeter pressure on a plane?
Above the TA, the aircraft altimeter pressure setting is normally adjusted to the standard pressure setting of 1013.25 hectopascals (millibars) or 29.92 inches of mercury and aircraft altitude will be expressed as a flight level.
What is the air velocity at a certain point on the wing?
Solution: When an airplane is flying 200 mph at 5000 ft altitude in a standard atmosphere, the air velocity at a certain point on the wing is 273 mph relative to the airplane. What suction pressure is developed on the wing at that point?
