The DLR project ALLFlight (Assisted Low-Level Flight and Landing on Unprepared Landing Sites) deals with the development of a helicopter pilot assistance system, to provide pilot assistance during all phases of flight. The research is particularly fo

A head-worn display combined with accurate head-tracking allows one to show synthetically generated symbols in a way that they appear as a part of the real world. Depending on the specific research context, different terms have been used for the abil

This article is about the design and evaluation of the human–machine interface of an enhanced and synthetic vision system. Several tunnel-in-the-sky and pathway-in-the-sky concepts including scene-linking elements have been evaluated. Pathway-in-th

Degraded visual environment (DVE) is a term coined for environmental conditions that impair the visual orientation of a helicopter pilot during flight or landing. These conditions include brown-out, but also night, glare, fog and mist, as well as com

Project ALLFlight is DLR's initiative to diminish the problem of piloting helicopters in degraded visual conditions. The problem arises whenever dust or snow is stirred up during landing (brownout/whiteout), effectively blocking the crew's vision of

Extending previous works by Doehler and Bollmeyer we describe a new implementation of an imaging radar simulator. Our approach is based on using modern computer graphics hardware making heavy use of recent technologies like vertex and fragment shader

To improve the situation awareness of an aircrew during poor visibility, different approaches emerged during the past couple of years. Enhanced vision systems (EVS - based upon sensor images) are one of those. They improve situation awareness of the

The generation of root signals of a two dimensional median filter with an arbitrarily specified window shape is treated in terms of a single special binary root signal that has been called the smallest surviving object (SSO). There is a unique relati
