Airport Components Matching: Runway & Hangar Design
This question requires matching different aspects of airport design (List I: Purpose) with the specific airport components they relate to (List II: Designed Component). Let's break down each match:
Understanding the Airport Design Matches
We need to connect the purpose of airport elements with the components designed for them.
List I: Purpose
- A. Basic Runway length
- B. Runway Capacity
- C. Runway geometric design
- D. Hangar
List II: Designed Component
- 1. Width and length of Safety area of airport
- 2. Housing, Servicing of aircrafts
- 3. Location of exit taxiways
- 4. Engine failure class
Detailed Explanation of Matches
A. Basic Runway Length and Engine Failure Class
The required Basic Runway length is heavily influenced by the performance of aircraft, particularly under emergency conditions like an engine failure during takeoff. The 'Engine failure class' (4) is a critical factor in determining the necessary runway length to ensure safety. Thus, A matches with 4.
B. Runway Capacity and Location of Exit Taxiways
Runway Capacity refers to how efficiently aircraft can use the runway for takeoff and landing. A key factor affecting this is how quickly aircraft can vacate the runway after landing. The 'Location of exit taxiways' (3) directly impacts this clearance time, thereby influencing the overall runway capacity. Therefore, B matches with 3.
C. Runway Geometric Design and Safety Area
The Runway geometric design encompasses the physical layout, dimensions, and safety features surrounding the runway. This includes essential safety margins. The 'Width and length of Safety area of airport' (1), often referred to as runway end safety areas (RESA) or overrun areas, is a fundamental part of the runway's geometric design for safety. Hence, C matches with 1.
D. Hangar Purpose
A Hangar is a specific structure at an airport. Its primary function is for the storage, maintenance, and repair of aircraft. This aligns directly with 'Housing, Servicing of aircrafts' (2). So, D matches with 2.
Summary of Matches
Based on the explanations, the correct matching is:
| A. Basic Runway length | 4. Engine failure class |
| B. Runway Capacity | 3. Location of exit taxiways |
| C. Runway geometric design | 1. Width and length of Safety area of airport |
| D. Hangar | 2. Housing, Servicing of aircrafts |
This corresponds to option 4: A - 4, B - 3, C - 1, D - 2.
Important Questions from Design of Airports
The point of intersection of the obstruction clearance line and the extended plane of the runway surface and the other end of the runway is called as:
For the hottest month of the year at the proposed airport site, the monthly mean of the average daily temperature is 390C. The monthly of the maximum daily temperature is 480C for the same month of the year. From the given information, the calculated Airport Reference Temperature (in 0C), is
Calculate the turning radius of the taxiway for an airport serving large subsonic jet planes. The design speed of turning is 60 kmph and assume friction coefficient between tyre and pavement surface as 0.15.
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 the 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 condition is 2000 m. Within the framework of applying sequential corrections as per the ICAO recommendations, the length of runway corrected for the temperature is
What is the airport reference temperature, if the monthly mean of average daily temperature for the hottest month of a study year = 24°C and the monthly mean of the maximum daily temperature for the same month of the same year = 30°C
