Railway airport docks and harbour ENGINEERING

Minimum gradient in station yards is generally limited to

• 1 in 1000
• 1 in 750
• 1 in 500
• 0

Indian Railway Nationalized in which year?

• 1955
• 1952
• 1950
•  1953

Rail section is generally designated by its

• Area of its cross-section
• Total weight
• Total length
• Weight per metre length

Conical surface of the approach area rises outwards

• 1 in 10
• 1 in 15
• 1 in 20
• 1 in 25

The yards in which wagons are stored and new trains are formed are called

• Station yards
• Goods yards
• Marshalling yards
• Junction yards

The FAA classification of the airport is based on:

• Length of Runway
•  Function
• Airport approach speed
• Geometric design

The minimum width of clearway is

• 200m
• 50m
• 100m
• 150m

Effective length of a runway is the distance between

• ends of the runway

• point of intersection of the obstruction clearance line and the extended plane of the runway surface, and the other end of the runway

• point of intersection of the glide path and the extended plane of the runway surface and the other end of the runway

• ends of the clear way on either side.

The meterological condition which influences the size and location of an air port is

• atmosphere pressure

• reduced level

• wind direction

• all the above.

The runway orientation is made so that landing and take off are

• against the wind direction
• along the wind direction
• perpendicular to wind direction
• none of these.
