Safe glide at total engine failure with ELA-inside

27.02.2017

On January 15, 2009, Chesley B. Sullenberger was celebrated world-wide: after the two engines had failed due to bird strike, he and his flight crew succeeded after a glide flight with an Airbus A320 in ditching on the Hudson River. All 155 people on board were saved.

An important aid to this horror flight could have been a new development, which Prof. Dr.-Ing. Wolfram Schiffmann from the FernUniversität in Hagen will present for the first time at Friedrichshafen International Fair for General Aviation AERO from 5 to 8 April:

A flight assistance system will help pilots in the event of a total engine failure. The Emergency Landing Assistant (ELA) offers decision-making and navigational assistance in order to control the aircraft precisely to glide to an area where a safe emergency landing is possible.

Each aircraft can fly without engines. The problem is, first of all, to find all possible landing sites that could be reached by a glide from the altitude where the engine(s) failed. For all those emergency landing sites ELA computes an optimized route that considers wind and other parameters of the current setup. Based on the remaining deadlines for the available landing sites ELA displays the alternatives to the pilot who has to decide for one of them.

After his decision, ELA provides the selected route by a flight director that could be used for manual control or even as a source for the autopilot. The ELA prototype was developed as an App for an Android tablet as part of a Bachelor's thesis by FernUni’s student Jürgen Vörding. Prof. Wolfram Schiffmann, who is a private pilot just like Vörding: "Because of the many parameters to be considered, the calculations are highly complex."

The investigations after 15 January 2009 showed the importance of fast decision making: "Sullenberger decided within seconds for the ditching. He could see the Hudson when the engines failed. In his situation an absolutely right decision! But, what if he had got a timely information by ELA that they could make it safely to La Guardia?

After a decision to there, he also would have got the opportunity to hand over navigation to the autopilot. This would have give him more time for communication with air traffic control until they reached the threshold of runway 13 of La Guardia in the best possible altitude for landing. Then he could have took control again and land the A320 there.

A first prototype of the ELA will be presented at AERO 2017. In a live demo you see by a flight simulation how the aircraft is directed from bird strike position to La Guardia Airport. If you can’t wait taste it here: http://e.feu.de/elavideo

Im Focus: The force of the vacuum

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.

The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
