A safe future

7 February 2012 | By Mark Glover, Commissioning Editor, International Airport Review

The issue of aviation safety has always produced comment, debate and input on a political global scale. Legislation is drawn up and adhered to although further harmonisation is required across the world for standards to become effective. This topic, as well as numerous other subjects were talked about and recently…

Friction testing through the years

8 December 2011 | By Armann Norheim, Leader of the ICAO Friction Task Force (FTF)

The history of the world includes many well known inventions which have had a significant influence on technological developments. One of these is the Dynamometer, a device used for measuring force, moment of force (torque) and power. Dynamometers have been a vital and necessary component in instruments that can identify…

Maintaining friction

10 June 2011 | By Armann Norheim, Leader of the IATA Friction Task Force (FTF)

In railroad engineering, the factor of adhesion of a locomotive is the weight on the driving wheels divided by the ‘starting tractive effort’. Adding extra power serves no purpose since there is not enough traction (adhesion, friction) to create useful work. The factor of adhesion which is 25% of the…

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.
