The airspeed calibration table converts indicated airspeed (IAS) to calibrated airspeed (CAS) by removing the calibration error. 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). The effect is an airspeed indicator reads lower than true airspeed at higher altitudes. In the following diagram you can find the distances h and l which are required for the calculation of the overturn of a vehicle.Density error occurs due to lower air density at altitude. The total time for braking is made up of reaction time and braking time. Overall stopping distance is the sum of braking distance and thinking distance. Formulas for Speed, Acceleration, Time & Distance.

So the car hits the obstacle at full speed! 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. In this case reaction distance is already greater than the total stopping distance from 1). This calculator will let you work out the acceleration and G force for an object over a set distance and time. The difference between the two numbers gives the reaction distance: 27.778 m. The total stopping distance is 38.701 m, the braking distance is 10.923 m. As „Reaction time“ choose 2 and replace the „Initial speed“ by a value of 50. Under these conditions, the car is still about 42 km/h fast!įirst reset the calculator. Let all the other values as they are – then select „Dry roadway“. The result is 33 km/h.įor this calculation, you have to put in the value 50 in the „starting velocity“ field. First, change the condition to „Wet roadway“ (click on the small arrow). If you want to find out the collision speed, the braking distance calculator must be filled out as shown in the screenshot below:Īfter entering the values, do not press the „Calculate“ button immediately.

For the correct answer, of course, the stopping distance has to be taken. To be able stopping just in time, the car must be 24.812 m away from the child.

In the „starting velocity“ field, you have to put in the value 50 instead of 100.

The car’s initial velocity is 50 km/h, a reaction time of two seconds is assumed. What stopping distance does the vehicle have?.

What’s the car’s speed when it is hitting the child? The stopping distance should be the same as in 1).

The driver runs illegally at 60 km/h through the village.

Now the road is wet. What’s the car’s speed at time of the accident?.

How far away from the child does the car have to be so that it can stop just in time? A reaction time of one second is assumed.

Obstacles – Effect of Speed or Reaction TimeĪ vehicle travels on a dry and even road through a village.

It is assumed that all the wheels are braked or driven.

In curves, there is less acceleration or deceleration possible.

The calculation is only valid for uniform acceleration or constant deceleration.Stopping (Braking) distance or acceleration distance.Depending on the road or rail conditions, the two calculators compute the following:.Reference Values for Acceleration or Deceleration.Obstacles – Effect of Speed or Reaction Time.Examples for the Use of these Calculators.Some Notes for the Use of the Calculator (manual).*** The meaning of the two abbreviations l and h can be found here: General Information. * Change the rail or road condition in the first calculator assumption: all wheels are braked.
