On doctors’ accountability and flight deck safety [PDF]
Croatian Medical Journal, 2015 People have an inherent tendency to view events as being more predictable than they may actually be, especially in hindsight. This predisposition is known as hindsight bias. However, putting hindsight bias aside, one should consider the discussion in the media raised by the recent Germanwings Flight 9525 air accident from a medical point of view.

Oil Fumes, Flight Safety, and the NTSB [PDF]
Aerospace, 2021 During its investigations into a series of ten aircraft crashes from 1979 to 1981, US National Transportation Safety Board (NTSB) officials were presented with a hypothesis that “several” of the crashes could have been caused by pilot impairment from breathing oil fumes inflight. The NTSB and their industry partners ultimately dismissed the hypothesis.

DeCGAN: Speech Enhancement Algorithm for Air Traffic Control
AlgorithmsAir traffic control (ATC) communication is susceptible to speech noise interference, which undermines the quality of civil aviation speech. To resolve this problem, we propose a speech enhancement model, termed DeCGAN, based on the DeConformer generative

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
