Abstract	The presentation gives a brief overview of the following recent and near future research activities at the DLR: Recent simulator and flight tests in the area of helicopter pilot assistance systems focused on the application of active sidesticks in order to provide haptic feedback, especially when reaching operational limits of the helicopter. In the DLR research simulator AVES a torque protection function was evaluated by pilots from DLR and German Army as well as German Air Force. The simulator trials are still ongoing. Preliminary evaluations show promising results based on gaze tracking measurements. Some years ago the DLR developed the first version of the so-called Low Noise Augmentation System (LNAS). This pilot assistance system is integrated into the Electronic Flight Bag software and supports the crew during the approach in order to optimize the timing of configuration changes. This optimization allows an idle thrust setting down to the 1000ft-gate resulting in noise and fuel consumption reduction. The system has been tested in several flight test campaigns using the DLR research aircraft Airbus A320 ATRA. As part of a new cooperation with Lufthansa LNAS has just been integrated into 86 airliners of the A320 family and is now tested in real airline operation. In August 2018 flight tests were performed in order to evaluate an innovative aircraft loads measurement technique. Instead of using strain gauges that have to be integrated into the aircraft structure this technique uses MEMS pressure sensors that are integrated in a wing glove. For the flight tests the DLR high-performance sailplane Discus 2c was used. During the production process this aircraft was equipped with 32 strain gauges that are integrated in the wing structure. A preliminary evaluation of the results shows a good correspondence between the wind load obtained from the strain gauge measurements and that resulting from the pressure distribution measured with wing glove equipped with the MEMS pressure sensors. In April 2018 DLR acquired a Dassault Falcon 2000LX that shall serve as a new In-flight Simulation testbed. The aircraft will be modified in three different stages. The presentation briefly describes the current status of the modifications.
