The Effect of an Unconscious Auditory Stimulus on Pilot Performance under Varying Instrument Flying Conditions
… performance under varying instrument flight (IFR) conditions on the aircraft flightdeck. Forty IFR student pilots underwent two eight-minute simulated flights, whereupon they were presented with different IFR weather conditions. During the trial, the experimental group listened to a UAS, …

Comparing the immediate free recall of verbal and visuo-spatial stimuli:List length, capacity and output order effects in single- and dual-modality tasks
… the items in any order (Immediate Free Recall; IFR), they tend to initiate their recall with the first list item when presented with short lists and with one of the last four items in longer lists. Chapter 2 examined whether this tendency necessitates a language-based retrieval mechanism by …

Multi-Method Approach to Understand Pilot Performance in a Sociotechnical Aviation System
… 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 terms of workload and especially situation awareness …

"Can religious treatment choices justify additional healthcare expenditure and, if so, are there limits to this?"
… treatment, Individual Funding Request (IFR) Panels within the NHS have to decide how to balance individual rights with the fair allocation of resources. This paper considers religious perspectives on healthcare treatments and whether, in respecting these, additional expenditure can be …

Behavioral Traps in Flight Crew-Related 14 CFR Part 121 Airline Accidents
… Descent Below an Instrument Flight Rule (IFR) Altitude. The purpose of this dissertation was to study the nature of their occurrence in the airline domain. Another key component was to explore the relationships between the behavioral traps and factors such as pilot age, pilot flight …

Ridge waves
… (JdFR, 4 days) and the Iceland-Faeroe Ridge (IFR, 1.8 days). Topographic cross sections of the ridges are fit by a double-exponential depth profile and the linearized shallow water equations are solved with the simplified topography. In the northern hemisphere the western ridge flank supports …

Comparing capacities and delays at major European and American airports
… control procedures, Instrument Flight Rules (IFR), American airports achieve equal or higher capacities than European airports with similar runway layouts. These discrepancies cannot be explained by the differences in separation requirements alone. Besides, through their extensive use of …

Crisp and Fuzzy Signal Detection Theory and Pilot Weather Judgment: Implications for VFR Flights Into IMC
… had trouble in distinguishing between VFR and IFR conditions, especially determining ceiling. Overall, pilots had a low sensitivity in determining whether the ceiling was VMC or IMC and tended to overestimate ceilings. This problem was amplified by an interaction with visibility. Pilots' …
