Airport Engineering — Part 1 MCQs with Explanations

Asphaltic concrete : This type of concrete is used to cope with high temperatures, such as 196°C. It has good resistance to temperature variations and is commonly used in the construction of taxiways and aprons. Rubberised tar concrete : While it can be used in some applications for its flexibility and durability, it is not typically used for withstanding very high temperatures like 196°C. Plain concrete : This type of concrete is not suitable for coping with very high temperatures as it can crack or deteriorate under such conditions. All the above : This option is incorrect because not all listed materials are suitable for high-temperature conditions. Therefore, to cope with high temperatures of 196°C, the taxiways and aprons are constructed with asphaltic concrete .

The lift off distance is a critical measurement in airport engineering. It refers to the distance along the center of the runway between the starting point and the point where the aircraft becomes airborne.
