Calculation the elevation difference if the vertical distance is 14.89m, instrument height is 9.2m, ground is at 2.8m.

Calculation the elevation difference if the vertical distance is 14.89m, instrument height is 9.2m, ground is at 2.8m. Correct Answer 21.29 m

The elevation difference in total station can be calculated as dz = Vd + (Ih-Rh). On substitution, we get dz = 14.89 + (9.2-2.8) dz = 21.29 m.

Consider the following statements regarding ICAO recommendation for correction to basic runway length of these statements
1. The basic runway length should be increased at the rate of 7 percent per 300 m rise in elevation above the mean sea level.
2. The basic runway length after having been corrected for elevation should be further increased at the rate of 1 percent for every 1°C rise in airport reference temperature above the standard atmospheric temperature at that elevation.
3. The runway length after having been corrected for elevation and temperature should be further increased at the rate of 20% for every 1 percent of effective gradient.
