In the beginning of air traffic history only propeller aeroplanes were used. They had a landing speed of 60-100 km/h, compared to today’s jet aeroplanes which have a landing speed of 250-360 km/h. Therefore, in the past when friction did not seem as important, the airport personnel used their feet to feel if it was slippery or not. In the 1930’s the friction test began to be performed by a bicycle or a car. After the foot friction test, there came a measuring device called ‘tapleymeter’: a small measuring device located in a car. To get a friction value, the car accelerates to 30 km/h and then the driver hits the brakes. This equipment is still in use at smaller airports today.
To ensure the safe take-off and landing of aircraft, it is essential for airports to provide pilots with an accurate assessment of runway surface conditions. Pär Blom explains the principles behind friction testing, one of aviation’s least celebrated, but most critical procedures.
