ASFT in Sweden have since May 20th, 1991 manufactured the original Saab Continuous Friction Measuring Equipment (CFME).

The owner of ASFT was at that time, approached by Saab Automobile AB and General Motors (GM) to manufacture and market the Saab CFME. This was a challenge that ASFT took on with great success. It also ensured the continued production and survival of the original Saab CFME, or SFT as it has become known to the world.

Today the ASFT SFT (original SFT) is a well proven CFME that is known around the world for being user friendly and reliable when it is needed the most. It has also been equipped with ASFT Mk IV rear-axle, and computer system. These systems have been developed for nearly 30 years, and with out most care taken to the feedback given from the 250 users around the world.

The operating system can today give completely automated SNOWTAM and CAP683 presentations. This is done in a MS Window environment, and it can also of course be integrated to an existing network.

ASFT and Runway Friction Measuring and Testing

ASFT also offers upgrades of old Saab 900 & 9000 to the latest rear-axle and computer system. This is a great opportunity to prolong the life expectance of an old CFME, and get the most out of invested capital. The original SFT have served the aviation industry for more then 30 years, and thanks to ASFT it will continue to excel in the future.

Author Information - Gunnar Antvik

Since the late forties Mr. Gunnar Antvik have been involved in friction measurements at airports. He began as a Manager of Performance Engineering of Scandinavian Airlines Systems, SAS. Therefore, airport friction characteristics were of concern to him. He then developed still used methods of determining friction characteristics at airports. These methods are all included in ICAO annex 14.
Mr. Gunnar Antvik was the spokesman in matters related to friction movements areas on airports for SAS, and in many cases also for IATA and for the Swedish Civil Aviation Administration as well. In the early fifties ICAO commissioned a work group that was lead by Mr. Gunnar Antvik. As a result the first guidelines for friction testing were included in Annex 14, 1952. In 1965 Mr. Antvik joined the Swedish Civil Aviation Administration, mainly to be able to represent Sweden at ICAO meetings. He was also appointed to be a member of the Runway Surface Condition Study Group, RSCSG. This group prepared material for ICAO meetings on friction measuring at airports around the world. Over the years Mr. Gunnar Antvik has accumulated considerable knowledge of challenges related to runway friction measuring.
