TLDR
In this paper, the authors consider the need for an ideal general aviation collision avoidance system, one which is selfcontained, non-cooperative in nature, transparent to the Air Traffic Control System, and fully compatible with TCAS and all other FAA proposals.Abstract:
Midair collisions are often perceived as the number‐one safety issue in aviation. Though the actual incidence of such accidents is (thankfully) small, public perception of the problem, and the government's reaction to it, may threaten the very future of general aviation. Midair collisions are primarily a general aviation problem. Its solution starts with the review of accident statistics and nearmidair report data, an exploration of prior art, and an understanding of the capabilities and limitations of TCAS (Threat alert and Collision Avoidance System), the FAA's supplement to visual traffic avoidance. This paper contemplates the need for an “ideal” general aviation collision avoidance system—one which is selfcontained, noncooperative in nature (requiring no equipment in the “other” plane), transparent to the Air Traffic Control System, and fully compatible with TCAS and all other FAA proposals.read more

A Quantitatively Derived NMAC Analog for Smaller Unmanned Aircraft Systems Based on Unmitigated Collision Risk
TL;DR: In this article, the authors explore quantitative criteria to use when simulating two or more smaller UASs in sufficiently close proximity that a mid-air collision might reasonably occur and without any mitigations to reduce the likelihood of a midair collision.

Near Midair Collision Analog for Drones Based on Unmitigated Collision Risk
TL;DR: In this article , the authors proposed a quantitative criterion to use when simulating two or more smaller drones in sufficiently close proximity that a mid-air collision might reasonably occur and without any mitigations to reduce the likelihood of a midair collision.

The influence of flight experience on midair collision risk perception.
TL;DR: It is hypothesized that pilot complacency, arising from a history of incident-free flights, plays a role in the midair collision process, and pilot risk perception is explored using Laplace's Law of Succession, and the resulting perceived collision probability compared to reality.

An Analysis of the Risk from UAS Missions in the National Airspace
TL;DR: In this article, Awad et al. presented first-order models adapted from the literature which estimate the risk due to these various scenarios, and verified these models through extensive analysis of historic civil aviation accidents.

Midair collisions - The accidents, the systems, and the Realpolitik
TL;DR: This paper examines collisions from a human factors perspective, seeing them as system-induced errors, resulting from an air traffic control system that emphasizes airspace allocation and political compromise, rather than dealing directly with the various problems facing controllers and pilots operating within the National Airspace System.

Binaural doppler collision alert system for general aviation aircraft
TL;DR: In this article, an aircraft collision avoidance system is disclosed which presents target or threat information to a pilot using a pair of doppler radar transceiver systems directed orthogonally about and centered on the user aircraft's pitch plane.
