This book was released on 1955 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A study has been made to develop a basic means, in the form of graphs and charts, for permitting a better understanding of cockpit visual problems and aircraft conspicuity problems as they are related to mid-air collisions. Formulas are derived and visual-angle and distance charts are presented for certain combinations of straight-and-level, climbing, descending, and turning flight conditions. Using only aircraft headings and speeds, the visual angles and distances between aircraft at assumed instances of time prior to collision may be determined from these charts. It is also possible to obtain critical collision-course headings by entering the charts with the effective cockpit cut-off vision angles and speeds. Tables are presented showing actual airplane attitudes during flight. Actual flight paths recorded in the vicinity of airports are presented. Some performance parameters used in the design of the visual-angle charts contained in this report were established from these flight-path data. From the graphs contained in this report, it is evident that: 1. No apparent motion from pilots' viewpoints exists between two aircraft which are flying straight and level on collision courses at constant speeds. 2. The most severe mid-air collision hazard from a visual-angle standpoint exists between aircraft that are flying at small differences of heading and speed. During this condition, even when the closing rates are small and much time is available for evasive maneuver, the visual-angle restrictions of present-day transport aircraft do not permit the pilots to observe each other. 3. Mid-air collisions cannot be avoided by use of the windshield area alone, since extreme visual angles may be required during many collision conditions. However, certain minimum visual angles in aircraft-cockpit design will tend to decrease the probability of mid-air collisions."--Summary.

Available in PDF, EPUB and Kindle. Book excerpt: "Conventional wisdom suggests aircraft midair collisions to be random events, governed by the laws of Brownian Motion, and best analyzed by stochastic methods. An alternative hypothesis, that such accidents are deterministic in nature, and that specific factors leading to midair collisions can be identified and mitigated, forms the basis for this Dissertation. A predictive model using case control theory is developed for assessing Risk Index, a criterion measure of midair collision likelihood, for any General Aviation flight, actual or hypothetical. Generating the model requires statistical validation of two independent near midair collision databases, and identifying within them those aircraft, aircrew and airspace characteristics most closely associated with collision risk. Calibration of the model shows reality to fall somewhere between the stochastic and deterministic assumptions. A statistically significant correlation is found between predicted and observed Risk Index for a sizable random sample of flights, with a resulting Coefficient of Determination of 0.25. This suggests that we have identified 25% of the source of variance in midair collision risk, the remaining 75% being random. Therefore we can realistically hope to reduce midair collisions by roughly 25%. Strategies for mitigating the identified causal factors are proposed. Measures to reduce the random, remaining 75% of collision risk are also explored. However, these appear to require a significant overhaul of Air Traffic Control procedures, which must be approached with caution, to guard against the attendant possibility of curtailing capacity in the Air Transportation System."--Page 1-2
