The following data is the airspeed calibration table for the airspeed indicator of the aircraft with zero flap deflection. Using this calibration table, the indicated airspeed (IAS) is determined from calibrated airspeed by modifying it with calibration error of the airspeed indicator. A calibration table is usually given in the pilot operating handbook (POH) or in other aircraft specifications. Position and placement of the static vent along with angle of attack and velocity of the aircraft will determine the pressure inside the airspeed indicator and thus the amount of calibration error of the airspeed indicator. Calibration error is the result of the position and placement of the static vent(s) to maintain a pressure equal to atmospheric pressure inside the airspeed indicator. Calibrated airspeed is equivalent airspeed modified with compressibility effects of air which affect the airspeed indicator.Ĭalibration error is specific to a given aircraft design. When flying at high altitudes and higher airspeeds, calibrated airspeed (CAS) is always higher than equivalent airspeed. Within the airspeed indicator, there is a certain amount of trapped air. This ability is reduced by an increase in altitude, an increase in speed, or a restricted volume. Equivalent airspeed is true airspeed modified with the changes in atmospheric density which affect the airspeed indicator.Ĭompressibility error occurs because air has a limited ability to resist compression. When the difference or error in air density at altitude from air density on a standard day at sea level is applied to true airspeed, it results in equivalent airspeed (EAS). To use this online calculator for Resultant of two forces acting on particle at 90 degrees, enter First Force (F1) & Second force (F2) and hit the calculate. The effect is an airspeed indicator reads lower than true airspeed at higher altitudes. 10^-11 N.Density error occurs due to lower air density at altitude. Gravitational constant G : input 6.674.m 1 unit : select ME (or mass of the Earth, equal to `5.972 × 10^24` kg).Unit of F : choose N (Newton) or another unit.To check this calculation, you may use the above calculator with the following inputs, Therefore, the gravitational force between the Earth and the satellite is `F = 7088 N`. Let's calculate the gravitational force between the Earth and the satellite. The distance between the center of mass of the Earth and the satellite is d = 7500 kilometers. The Earth-Moon gravitation force is approximately `F = 1.98*10^20 N`Įarth-Moon gravitation force Exemple 2 : Gravitational force between the Earth and artificial satelliteĪ satellite of mass m 1 = 1000 kg orbits around the Earth, which has a mass of m 2 = 5.972 × 10^24 kg. 151 / 32 4.74 Gs experienced by the drivers. The acceleration due to gravity (1 G) is 32 f/s2.

G is the universal gravitational constant whose value is,Įxample 1. These forces have the same intensity F equal to,į is the force of attraction between the two bodies in Newton,ĭ is the distance between the two bodies in meter.The forces exerted by body 1 on body 2 (`\vecF_12`) and vice versa by body 2 on body 1 (`\vecF_21`) are vector opposite,.The calculator assumes that the object starts from a stationary position, and accelerates at a constant rate for the whole time. Enter a distance in kilometers and a time in seconds, then just press the Find Acceleration button. According to the universal law of gravitation formulated by Isaac Newton in 1687, two bodies of mass `m_1` and `m_2` spaced at distance d, exert one on the other a force of attraction according to the following laws : This calculator will let you work out the acceleration and G force for an object over a set distance and time.
