## Airport Engineering Assertion A : Airport capacity during IFR conditions is usually less than that during VFR conditions.Reason R: During clear weather condition (VFR), the aircrafts on final approach to runway can be spaced closer during poor visibility conditions.Select your answer based on the coding system given below:

A is false but R is true
Both A and R is true and R is the correct explanation of A
A is true but R is false
Both A and R is true but R is not the correct explanation of A

## Airport Engineering Assertion A : The ratio of arriving and departing aircrafts influences the airport capacity:Reason R : Landing operation is generally given priority over the taking off operation.Select your answer based on the coding system given below:

## Airport Engineering Consider the following statements regarding ICAO recommendation for correction to basic runway length of these statements1. 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.
