List of top Transportation Engineering Questions on Concept of airport runway length asked in GATE CE

The primary purpose of the Windrose diagram is for the design of
Given the following conditions, determine the value of the 15-minute Peak Hourly Factor (PHF): Given:
- Vehicles in the peak hour come in 10-minute intervals
- Find the value of the 15-minute PHF
Runway length after elevation and temperature correction is 700 m. The effective gradient is 1%. Find the final corrected length.
The longitudinal sections of a runway have gradients as shown in the table.
End to end for sections of runway (m)Gradient (%)
0 to 200+1.0
200 to 600-1.0
600 to 1200+0.8
1200 to 1600+0.2
1600 to 2000-0.5
Consider the reduced level (RL) at the starting point of the runway as 100 m.
The effective gradient of the runway is
As per the International Civil Aviation Organization (ICAO), the basic runway length is increased by x (%) for every y (m) raise in elevation from the Mean Sea Level (MSL). The values of x and y, respectively, are
The base length of the runway at the mean sea level (MSL) is 1500 m. If the runway is located at an altitude of 300 m above the MSL, the actual length (in m) of the runway to be provided is _________ (round off to the nearest integer).

The longitudinal section of a runway provides the following data: \[ \begin{array}{|c|c|} \hline \text{End-to-end runway (m)} & \text{Gradient (\%)} \\ \hline 0 \text{ to } 300 & + 1.2 \\ 300 \text{ to } 600 & - 0.7 \\ 600 \text{ to } 1100 & + 0.6 \\ 1100 \text{ to } 1400 & - 0.8 \\ 1400 \text{ to } 1700 & - 1.0 \\ \hline \end{array} \] The effective gradient of the runway (in %, rounded off to two decimal places) is \(\underline{\hspace{2cm}}\).
