Friction testing at Swedish airports

5 April 2010 | By Fredrik Nilsson, Airport Engineer, LFV Group

There are many parameters that have an impact on the aircraft traffic at an airport. Wind and runway conditions are some of the parameters needed for the pilot to calculate if he or she can take off or land at an airport. The friction value is one of the parameters…

Prevention of Runway Incursions at Joint Use Aerodromes

16 July 2009 | By Goran Redzepovic, Eurocontrol Military Expert

Runway Safety is a vital component of aviation safety as a whole. The predicted growth in air traffic implies that the actual numbers of incidents may rise, unless held in check by preventive actions such as those recommended in the European Action Plan for the Prevention of Runway Incursions (EAPPRI).…

Runway Friction Measurement Status

7 February 2009 | By Thomas J. Yager, Distinguished Research Associate, NASA Langley Research Center, Hampton, Virginia USA

With today's technology, the measurement of ‘friction' can be readily and accurately determined whether it be in a vehicle engine, wheel bearing, or of more immediate attention, the interface between a moving vehicle tire and the travelled pavement surface. In regards to ground vehicle and aircraft operations, the problem is…

Airport pavement rehabilitation by rubblisation

30 September 2008 | By Dr. Navneet Garg, Project Manager, Airport Technology R&D Branch, William J. Hughes Technical Center, Federal Aviation Administration

Concrete pavements exhibiting distresses such as cracking, joint deterioration, spalling, and joint faulting can be rehabilitated by constructing a concrete or asphalt overlay. The ‘crack and seat’ technique is the most prevalent method for deteriorated concrete pavement rehabilitation. However, ‘rubblisation’ is fast becoming a popular method of concrete pavement rehabilitation.

Development of friction testing in the UK

28 March 2008 | By Paul Fraser-Bennison, Aerodrome Standards Policy Officer, UK CAA Safety Regulation Group

On 6 February 1958, an aircraft crashed whilst making its third attempt to take off from Munich's Reim Airport. Twenty-three of the passengers and crew on board were killed. After a lengthy investigation, the cause of the accident was identified as slush on the runway. Fifty years later, this event…

Friction testing in Sweden

30 November 2007 | By Fredrik Nilsson, Project Manager, Civil Engineering Department, Swedish CAA at Stockholm-Arlanda Airport and Pär Blom, Training officer, Field Department, Stockholm-Arlanda Airport

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…
