(B) 20°
(C) 30°
(D) 40°

2. Consider the following statements regarding ICAO recommendation for correction to basic runway length
• 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.
