Frequently, helicopter offshore missions are conducted in rough environments under adverse conditions. Specific operations, like hoisting close to a wind turbine or offshore platform landings, require special maneuvers and procedures in order to incr

In the past couple of years research on display content for helicopter operations headed a new direction. The already reached goals could evolve into a paradigm change for information visualization. Technology advancements allow implementing three-di

Helicopter operations require a well-controlled and minimal lateral drift shortly before ground contact. Any lateral speed exceeding this small threshold can cause a dangerous momentum around the roll axis, which may cause a total roll over of the he

Degraded visual environment is still a major problem for helicopter pilots especially during approach and landing. Particularly with regard to the landing phase, pilot’s eyes must be directed outward in order to find visual cues as indicators for d

A combination of see-through head-worn or helmet-mounted displays (HMDs) and imaging sensors is frequently used to overcome the limitations of the human visual system in degraded visual environments (DVE). A visual-conformal symbology displayed on th

In 2008, the German Aerospace Center (DLR) started the project ALLFlight (Assisted Low Level Flight and Landing on Unprepared Landing Sites). The aim of the program is to integrate a full scale enhanced vision sensor suite in DLR’s research helicop

Poor visibility can pose a serious safety hazard in helicopter flight, leading to a loss of situation awareness, spatial disorientation, and high pilot workload. Therefore, the use of helmet-mounted displays recently became increasingly important for

Helicopter guidance in situations where natural vision is reduced is still a challenging task. Beside new available sensors, which are able to “see” through darkness, fog and dust, display technology remains one of the key issues of pilot assista
