The contributing factors for viscous hydroplaning are a damp or wet pavement, medium to high speed, poor pavement texture, and worn tire tread. If a runway has good microtexture and grooving and the aircraft tires have a good tread design, viscous hydroplaning could be alleviated.(NTSB, p.92) Macrotexture is visible to the naked eye.
Uniform Tire Quality Grading, commonly abbreviated as UTQG, is a set of standards for passenger car tires that measures a tire's treadwear, temperature resistance and traction. The UTQG was created by the National Highway Traffic Safety Administration in 1978, a branch of the United States Department of Transportation (DOT). [ 1 ]
For passenger and light truck tyres, the manufacturers or importers have the choice of either putting a sticker on the tyre tread or a label accompanying each delivery of batch of tyres to the dealer and to the end consumer. The tyre label will use a classification from the best (green category "A") to the worst performance (red category "G").
Several public transit bus services operate bus routes to Toronto Pearson International Airport. Toronto Transit Commission (TTC) operates daily, 24-hour public transit bus service from Pearson Airport to various subway stations in Toronto, with route 900 Airport Express being the main express bus service to the airport from Kipling station on ...
Design of tire tread has an effect upon noise generated, especially at freeway speeds. [1] Generally there is a tradeoff of tread friction capability; deeper patterns often enhance safety, but simpler designs are less costly to produce and actually may afford some roadway noise mitigation.
TWI: Tread wear indicator – a device, such as a triangle or a small Michelin Man icon, located where the tread meets the sidewall, and indicating the location of the raised wear bars in the tire tread channels – TWI is also used to refer to the raised wear bars themselves. VSB: Vertical serrated band; WSW: White sidewall
[2] [3] These aviation facilities are situated within and around Toronto and its neighbouring cities, serving airline passengers, regional air travel and commercial cargo transportation. Toronto Pearson International Airport, located mainly in Mississauga, is the busiest airport in Canada and hosts international travel with various airlines.
