Question

3 survey crews completed differential level loops. The total distances and misclosures were:

Crew 1 : Distance of loop = 896m; misclosure = 0.025m

Crew 2 : Distance of loop = 543m; misclosure = 0.016m

Crew 3 : Distance of loop = 761m; misclosure = 0.024m

Calculate the maximum 3^rd order allowable accuracy for each crew; i) Crew 1 , ii) Crew 2 , ii) Crew 3 , iv) which crew did not acceptable 3rd order accuracy for their level loop?
