Real Emergency Landing Exercise
Real emergency landing exercise with a Katana DV20. This video shows a simulated emergency landing at Arnsberg-Menden Airport (EDLA or FAM). The pilot approached the airfield inbound to southeast and set the engine to idle at about 1600 ft above the center of the runway. Then he flew at the speed of best gliding (65-70 kn) along the route prescribed by ELA and reached the runway threshold at the right height for landing. The ELA glide path was calculated for the current wind situation (from 190 to 7kn) and is displayed in the navigation software AirNavigationPro.
Engine-out in IMC
Emergency landing in blind flight. In this video you can see an emergency landing approach at instrument flying conditions (IMC). Due to the high speed of the glide path calculation by the moving target method, it is possible to make an emergency landing even with complete loss of visibility. This is demonstrated here on the flight simulator for an emergency landing on the airfield Santa Cilia De Jaca.
Fixed wing drone autopilot landing
In the video you see our latest achievements regarding autonomous engine-out emergency landing. The drone has an autopilot that is controlled by our moving target algorithm to safely guide the drone to an emergency landing field. In contrast to trochoid based approaches it is one million times faster and can run on an embedded microprocessor. The integration of the moving target algorithm into an autopilot-controlled fixed wing model airplane was realized as part of a master thesis by Nikolai Voget. We work towards to integrate it into a real airplane as well.
The Flare Assistant (FA) helps pilots to make a smooth touchdown. Pilots are guided by a so called smart flight director SFD that indicates how they have to move the elevator. If the red disc is within the circle no action is required because the aircraft is on track for a perfect landing. Also audio signals announce the flare altitude and loud beeps require pulling the elevator. If there are no audio hints the aircraft is on track.
The Thermals Assistant (TA) visualizes the thermal situation around the sailplane. It leaves a trace of red or blue dots along the flight path. The red dots indicate upwind and should be circled it order to gain height. The small line in heading direction helps the pilots to accomplish this task.
On the following video you can see our "Circling Autopilot" in action. We developed that Autopilot in connection with a graphical tool called "Variomap" that illustrates the thermal situation around a sailplane and helps the pilot to get more lift out of the thermals. By means of the Circling Autopilot the human pilot has just to guide the airplane close to the thermal and then the Autopilot takes care for centering the thermal.
