Until now, orange balloons on power lines, brightly painted masts and lights have been the only warning that pilots receive when they are approaching and obstacle. But bad weather and poor light may reduce visibility to the point at which it is impossible to see an obstacle before it is too late.
The new warning system, which two Norwegian pilots have developed in collaboration with SINTEF, warns pilots of a collision hazard irrespective or weather and visibility conditions. The system continuously monitors the air-space in the vicinity of a hazard, and warns pilots by radio of the danger of collision.
The five scientists involved in the project have just shared SINTEF’s 2006 Prize for Outstanding Research. The award which is worth NOK 100 000, can go to current or former employees of the SINTEF Group.
The core of the system is a high-technology mast that is installed near the obstacle. The mast houses radar and information systems that register whether an aircraft is on course to collide with the hazard.
When the aircraft is 30 seconds away the system actives powerful flashing lights. If avoiding action is not taken by the time that the aircraft is 20 seconds off and it continues on a collision course, a VHF transmitter in the mast is activated. This gives the pilot a clear and easily recognisable auditory signal, which is transmitted over all VHF air traffic channels in order to ensure that it reaches the pilot.
Available for everyone.
The system does not require any special installation or added investment in aircraft themselves. It warns any planes that is in danger of colliding with an obstacle, irrespective of its type or nationality.
Pilots Rolf Bakken and Morten Mørk had the idea of a radio warning system for pilots in 1999. They approached SINTEF, which completed the system with radar technology in order to prevent it from giving false alarms to planes that were not actually on a collision course with an obstacle.
In 2000, Bakken and Mørk set up a new company, Obstacle Collision Avoidance System (OCAS) AS to produce and market the system. The company’s premises are in Oslo, and it has 17 employees.
To date, three trial systems have been installed in Norway, and test flights have confirmed that they work as they were intended to do.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
