Q4. A runway is being constructed in a new airport as per the International Civil Aviation
Organization (ICAO) recommendations. The elevation and the airport reference temperature
of this airport are 535 m above the mean sea level and 22.65°C, respectively. Consider the
effective gradient of runway as 1%. The length of runway required for a design-aircraft under
the standard conditions is 2000 m. Within the framework of applying sequential corrections as
per the ICAO recommendations, the length of runway corrected for the temperature is
