Pick up the incorrect statement from the following: A. Channelization of pavement is caused by constant use of tri-cycle gears of aircraft B. Blast pads are used over cohesion-less soils to resist erosion due to tremendous speed of the jet blast C. Over-run areas of at least 300 m length on either side of the runway are provided D. None of these

None of these

The correct answer is A. Channelization of pavement is caused by constant use of tri-cycle gears of aircraft.

Channelization of pavement is caused by the following:

  • The weight of the aircraft
  • The pressure of the tires
  • The friction between the tires and the pavement
  • The water on the pavement

The tri-cycle gear of an aircraft is a type of landing gear that has two main wheels and a nose wheel. The main wheels are located near the center of the aircraft, and

the nose wheel is located at the front of the aircraft. The tri-cycle gear is designed to provide stability and control during takeoff and landing.

The tri-cycle gear does not cause channelization of pavement. Channelization of pavement is caused by the factors listed above.

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 to allow aircraft to come to a safe stop in case of an emergency.
