Introduction Fly levelling is a very approximate form f orm of levelling in which sights are taken as large as possible. In this method a line of levels is run to determine determine approximately approximately reduced levels of the points carried out with more rapidly rapidly and less precision. precision. It is a levelling that is done to connect benchmark to the starting point of the survey line.

Then he proceeds towards the site by taking fore sights and back sights on a number of change points till he establishes a temporary benchmark in the site. +est of the levelling work is carried out in the site. t the end of the work again levelling is carried out by taking a set of convenient change points till the bench work is reached. This type of levelling in which only back sight and fore sights are taken* is called fly levelling* the purpose being to connect a benchmark with a temporary benchmark or vice versa. Thus the difference between fly levelling levell ing and differential levelling is only in the purpose of levelling.[ CITTI!"

!bjective The purpose of fly levelling is to check the values of the reduced levels of the bench marks already fixed. In this method only backsight and foresight are taken. There is no need of intermediate sights. 5owever great care has to be taken for selecting the change points and for taking reading on the change points because the accuracy of levelling depends upon these. -econdly* to determine the height of one level relative to another. It is used in surveying to establish the elevation of a point relative to a datum or to establish a point at a given elevation relative to a datum. [ CITTI!" +a6$( &l $'($' ) Thirdly* fly levelling is to determine the differences in elevation between points on the earth7s surface. 4evelling is importance in ac8uiring data for the design of a wide variety of civil engineering works such as highways* railways* damns* canals* tunnels* irrigation and drainage works. 4evelling also helps the construction engineer and contractor in executing all such jobs. [ CITTI!"

This will save times and prevent the wastages of materials.[ CITTI!" sam$$ &l $'($' )
