Investigation and Evaluation of a Computer Program to Minimize VFR Flight Planning Errors
… After the subjects completed a conventional VFR navigation log, they were asked to plan the return trip of the flight using a computer aided flight plan. It was initially expected that the computer aided flight plans would have fewer flight planning errors than those calculated using …

Crisp and Fuzzy Signal Detection Theory and Pilot Weather Judgment: Implications for VFR Flights Into IMC
… 90% are attributed to visual flight rules (VFR) flight into instrument meteorological conditions (IMC). The situation assessment hypothesis suggests that pilots may inadvertently enter IMC because they lack the sensitivity needed to distinguish between visual meteorological conditions (VMC) …

UNEXPECTED TRANSITION FROM VFR TO IMC: AN EXAMINATION OF TRAINING PROTOCOLS TO MITIGATE PILOT GAPS IN KNOWLEDGE AND PERFORMANCE
… accidents identified as Visual Flight Rules (VFR) into Instrument Meteorological Conditions (IMC). These accidents have a nearly 90% fatality rate and hundreds of people have been fatally injured (ASI, 2014a). The general aviation community, including the Federal Aviation Administration, has …

An Aviation Weather Preflight Decision Support Tool to Improve GA Pilots' Preflight and Inflight Performance
… US university. Forty-one visual flight rule (VFR) private pilots were randomly assigned to the control group (no preflight decision tool) and 37 VFR private pilots were assigned to the experimental group (preflight decision tool). Participants performed a weather preflight and a simulated …

Multi-Method Approach to Understand Pilot Performance in a Sociotechnical Aviation System
… between pilots who flew by visual flight rules (VFR) and those who flew by instrument flight rules (IFR) or within each of these pilot groups in terms of objective flight performance. However, there were several significant differences between VFR and IFR pilots and within each pilot group in …

Optimizing aerobot exploration of Venus
Venus Flyer Robot (VFR) is an aerobot—an autonomous balloon probe—designed for remote exploration of Earth's sister planet in 2003. VFR's simple navigation and control system permits travel to virtually any location on Venus, but it can survive for only a limited duration in the harsh Venusian …

Investigating Pilot Performance Using Mixed-Modality Simulated Data Link
… In the second study, 16 visual flight rules (VFR) rated pilots were evaluated for their data link performance using a flight simulator (ELITE i-GATE) equipped with a mixed-modality simulated data link within one of two flight conditions. Data link modalities included textual, synthesized …

Factors Contributing to Weight Loss Induced by Intraventricular 6-Hydroxydopamine Lesions in Diabetes (db/db) Mice.
… and with a food restricted db/db vehicle group (VFR). Both 6-OHDA treatment and food restriction produced weight loss in db/db mice. Furthermore, 6-OHDA lesions suppressed food intake in diabetes mice. Blood glucose and body fat were reduced in both 6-OHDA and VFR db/db groups. However, in order …

Visualisation of chemistry in flow
… agar gelling agent and in a vortex flow reactor (VFR). The agar system allowed the production of FDO patterns in the absence of a packing material and could be forced by a periodic change in reaction temperature. Synchronisation was found in space-time but not time. This was in contrast to …
