For night landing, the thresholds are lighted

In approach areas of runways equipped with instrumental landing facilities any object within 4.5 km distance from runway end shall be considered as an obstruction if its height is more than

Castor angle is defined as the angle

For supersonic transport aircraft, the minimum turning radius of taxiway is

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.

Airport elevation is the reduced level above M.S.L. of

As per UK design criteria, if LCN of aircraft is between 1.25 to 1.5 times the LCN of pavement, then the number of movements allowed are

According to ICAO, all markings on the runways are

For Class ‘A’ Air port the difference of reduced levels of higher and lower edges of the conical surface, is

A gradient of + 0.08% is followed by a gradient of - 0.07%. If the permissible rate of change of grade is 0.003 per 30 meters, the length of the transition curve, is
