This study analyzed currently available data specifically related to the reliability of digital avionics systems. It examined the relationships between reliability and airworthiness standards, maintenance programs, integrity, and safety.
Estimation of collision risk is an important technique used to assess the safety of current and proposed air traffic control route-separation standards. The collision risk model separates this risk into independent lateral, vertical, and longitudinal risks.
An evaluation of selected Flight Service Automation System (FSAS) Model 2 functions was conducted at the Federal Aviation Administration (FAA) Technical Center. Selected weather and flight data messages were extracted from the FSAS Model 2 specifications (FAA-2684, Volume II, Model 2 Software) and programmed into a system designed to simulate the s

The Moving Target Detector is capable of providing a direct measurement of the radial velocity of a target. However, the velocity measurements are ambiguous, and several algorithms were considered for resolving the ambiguities. Only one algorithm was found which gave the required accuracy in resolving the velocity ambiguities. The measured radial v

A data collection program is described which would provide much useful information related to lateral pathkeeping performance of aircraft flying low-altitude VOR-defined airways. This data collection would provide specific information which would complement the information previously gained concerning the high-altitude VOR-defined jet route environ

Concept designs of the future en-route sector control suites, fabricated in full-scale, were assessed by Federal Aviation Administration air traffic control specialists with regard to human factors considerations. Potential hardware and software enhancements of the sector control positions were simulated with mockups and used to demonstrate possibl

Caution Bars (stop bars or hold bars) are used to identify taxiway hold lines and warn pilots of an approaching runway. Caution Bars are difficult to see when they are covered by snow or sand, or when a high-cockpit aircraft is at or close to the caution bars. Under these conditions, supplemental lights (taxi-holding position lights) could help. Th

This report addresses the challenges of integrating artificial intelligence (AI) and machine learning (ML) technologies into aviation while ensuring safety and reliability. AI/ML applications in areas such as autonomous flight control and collision avoidance show great potential, but there is uncertainty around how to employ them and certify them c

Frost that forms on the surface of wings with fuel remaining in integrated fuel tanks following a flight is referred to as cold soaked fuel frost. Frost roughness was characterized using two experimental facilities which provided different methods for capturing the thermodynamic environment representing the cold soaked fuel frost growth process. A
