Flight Deck-Based Delegated Separation: Evaluation of an On-board Interval Management System with Synthetic and Enhanced Vision Technology
نویسندگان
چکیده
An emerging Next Generation Air Transportation System concept Equivalent Visual Operations (EVO) can be achieved using an electronic means to provide sufficient visibility of the external world and other required flight references on flight deck displays that enable the safety, operational tempos, and visual flight rules (VFR)-like procedures for all weather conditions. Synthetic and enhanced flight vision system technologies are critical enabling technologies to EVO. Current research evaluated concepts for flight deck-based interval management (FIM) operations, integrated with Synthetic Vision and Enhanced Vision flight-deck displays and technologies. One concept involves delegated flight deck-based separation, in which the flight crews were paired with another aircraft and responsible for spacing and maintaining separation from the paired aircraft, termed, “equivalent visual separation.” The operation required the flight crews to acquire and maintain an “equivalent visual contact” as well as to conduct manual landings in low-visibility conditions. The paper describes results that evaluated the concept of EVO delegated separation, including an off-nominal scenario in which the lead aircraft was not able to conform to the assigned spacing resulting in a loss of separation.

Examining New Flight Deck Technology Using Human Performance Modeling
Aircraft flight deck synthetic vision systems (SVS) always provide a “clear day” view and hence have the potential to improve safety in commercial aviation. Approach, landing, and taxi operations will most readily profit from the SVS capabilities. A part-task simulation study provided data on pilot performance using a baseline and an SVS-equipped flight deck. One effect of adding the separate S...

Limited visibility and reduced situational awareness have been cited as predominant causal factors for both Controlled Flight Into Terrain (CFIT) and runway incursion accidents. NASA’s Synthetic Vision Systems (SVS) project is developing practical application technologies with the goal of eliminating low visibility conditions as a causal factor to civil aircraft accidents while replicating the ...

This paper describes a system for landing a vertical take-off and landing vehicle on a moving deck using a monocular vision system and inertial measurement unit. Data from the vision system and IMU are used to compute an estimate of relative deck position, and a touchdown trajectory generator based on tau-guidance is used to compute a path to landing. A trajectory-following controller follows t...
متن کاملComparison of Controller and Flight Deck Algorithm Performance During Interval Management with Dynamic Arrival Trees (STARS)
Managing the interval between arrival aircraft is a major part of the en route and TRACON controller’s job. In an effort to reduce controller workload and low altitude vectoring, algorithms have been developed to allow pilots to take responsibility for, achieve and maintain proper spacing. Additionally, algorithms have been developed to create dynamic weather-free arrival routes in the presence...
متن کاملSelecting the Visual Landing Markers Located on a Ship Deck for UAV Automatic Landing
Of all the flight modes of unmanned aerial vehicles (UAVs), the landing approach and the landing itself are the most difficult and dangerous ones. To perform an automatic landing on a ship deck using a computer vision system (CVS), a UAV must analyze the visual landing markers located on the deck. When the UAV is about to start landing, these markers must be clearly visible and discernible. The...
