The laser sensor of ALLFlight (Assisted Low Level Flight and Landing on Unprepared Landing Sites) is integrated into the small box below the helicopter. In the framework of DLR's ALLFlight research project, scientists are developing a system to generate a digital map for the cockpit and assist the pilots in difficult situations - up to a fully automated landing.

The cyclic stick – responsible for movements about the longitudinal axis (roll) and the transverse axis (pitch) – is missing from the myCopter steering wheel system. One stick remains, exclusively responsible for altitude. Alternatively, this aspect could be controlled using a paddle fitted to the steering wheel. Just as with the accelerator and brake in a car, the pedals control speed and can even cause the vehicle to hover. An eight-way switch on the myCopter steering wheel controls reverse and lateral flight. The steering wheel has already completed its maiden flight in the virtual environment of the Air Vehicle Simulator (AVES) operated by DLR in Braunschweig.
The Göttingen-based researchers employed a novel technique to visualise the rotor blade vortices, using the loose scree littering the quarry as a background for their measurement method.
Blade tip vortices are visible as dark lines during a full rotation of the main rotor. The engine exhaust flows are perceptible as a noisy area trailing the helicopter. The tail rotor's vortex system is also visible (black, circular lines on the tail rotor). The helicopter is currently performing a rocking manoeuvre.
For the measurement campaign, a series of microphones were positioned at various places inside the engine and around the exhaust area and recording their signals simultaneously. These signals formed the basis for the acoustic field analysis.

During a test flight, ACT/FHS uses the ALLFlight (Assisted Low Level Flight and Landing on Unprepared Landing Sites)system for landing.
Part of the team involved in DLR's research project ALLFlight (Assisted Low Level Flight and Landing on Unprepared Landing Sites), which will develop a system to create a digital environment map for the cockpit and help the pilots in difficult situations - up to a fully automatic landing. The last succesful test flight of 2011 was conducted with the DLR research helicopter ACT/FHS (Active Control Technology/Flying Helicopter Simulator) on Monday, 5 December 2011.
