Airport Engineering Set 3

Air screw converts the energy given by the engine into speed The propellers which are driven by turbine engines, are technically called turboprops The aircrafts which obtain the thrust directly from turbine engine, are called turbo-jets All the above

Approach zone survey is carried out to determine the elevations of the protruding obstructions above horizontal, conical and transitional surfaces The wind data of an air port is depicted in the form of a chart known as wind rose The landing and takeoff of the air craft is made against the wind direction All the above

Approximate geometric centre of the landing area, is called air port reference point The boundaries of horizontal surface and conical surface are marked with reference to air port reference point The location of the air port on a map is the position of air port reference point All the above

Channelization of pavement is caused by constant use of tri-cycle gears of aircraft Blast pads are used over cohesion-less soils to resist erosion due to tremendous speed of the jet blast Over-run areas of at least 300 m length on either side of the runway are provided None of these

F.I.R. stands for flight information regions Radius of control area is 160 km Radius of control zone is 40 km All the above
