calibrated airspeed การใช้

• Likewise, the calibrated airspeed is a function of the compressible impact pressure.
• At standard sea level pressure, calibrated airspeed and equivalent airspeed are equal.
• At standard sea level conditions, true airspeed, calibrated airspeed and equivalent airspeed are all equal.
• When input to an airspeed indicator, impact pressure is used to provide a calibrated airspeed reading.
• The calibration equation ( see calibrated airspeed ) accounts for compressibility, but only at standard sea level pressure.
• In some very high speed aircraft such as the Space Shuttle, equivalent airspeed is calculated instead of calibrated airspeed.
• At standard sea level, EAS is the same as calibrated airspeed ( CAS ) and true airspeed ( TAS ).
• At high speeds and altitudes, calibrated airspeed must be further corrected for compressibility error to give equivalent airspeed ( EAS ).
• In some applications, notably British usage, the expression " rectified airspeed " is used instead of calibrated airspeed.
• In many aircraft, the effect of position error on airspeed is shown as the difference between indicated airspeed and calibrated airspeed.

• If the higher'actual', though not-indicated, V MC ( A ) increases above the actual calibrated airspeed, control will be lost.
• At this point, the " Clipper Maid of the Seas " was flying at on a heading of 316 degrees magnetic, and at a speed of calibrated airspeed.
• The IAS is not the actual speed through the air even when the aircraft is at sea level under International Standard Atmosphere conditions ( 15 癈, 1013 CAS ( Calibrated Airspeed ).
• Most aircraft exhibit a small difference between the airspeed actually shown on the instrument ( indicated airspeed, or IAS ) and the speed the instrument should theoretically show ( calibrated airspeed or CAS ).
• The evaluation flights showed that the aircraft has a glide ratio of 31 : 1 at calibrated airspeed ( 48 mph, 78 km / h ), the same glide ratio claimed by the factory.
• When flying at sea level under International Standard Atmosphere conditions ( 15 癈, 1013 hPa, 0 % humidity ) calibrated airspeed is the same as equivalent airspeed ( EAS ) and true airspeed ( TAS ).
• In simple aircraft, without an air data computer or Machmeter, true airspeed can be calculated as a function of calibrated airspeed and local air density ( or static air temperature and pressure altitude which determine density ).
• In addition, when the thrust is asymmetrical, a long straight-in approach should be considered, rather than a tight final turn during which the thrust might have to be increased to maximum and control will be lost because actual V MC ( A ) increases above the calibrated airspeed ( figure 4 ).
• Aircraft falling within the US ultralight specifications are extremely lightweight ( less than 254 pounds if powered, or 155 pounds if unpowered ), are intended for manned operation by a single occupant, have a fuel capacity of five US gallons ( about 19 litres ) or less, a maximum calibrated airspeed of not more than, and a maximum stall speed of not more than.
