Rotorcraft Pinnacle Landing Situational Awareness System

摘要

One of the most hazardous landing scenarios for rotorcraft is the pinnacle landing. During pinnacle landings the flight crews approach areas where traditional landings are not possible and place a portion of the aircraft on the ground (e.g. skids or back wheels) in order to extract or drop off passengers in challenging terrain. These landings are used for such operations such as air assault and mountain search and rescue. In these situations, the flight crew must perform precise maneuvers in close proximity to hazards with minimal visibility. Typically, crew members provide aural cues to the pilot to guide the aircraft. These maneuvers are proven to be demanding and have led to many accidents. Boeing is developing a sensor based pilot situational capability to aid the flight crews during pinnacle landings. We will present the design trade space and operational parameters that informed our approach. In addition, we will discuss the system development, testing and human factor considerations.
