Takeoff and Turbulence in Modernizing Peru

Modernizing WAAS

The Wide Area Augmentation System (WAAS) became operational on July 10, 2003. Currently this system provides en-route through non-precision approach guidance. Further, the signals are capable of providing vertical guidance to bring an aircraft within 250 feet of the ground. WAAS offers significant benefit to both aviation and non-aviation users. However, the vertical guidance availability is vu...

Modernizing the informal sector

Th e multiplicity of policies proposed to support the informal sector refl ects the lack of a common defi nition. Although they may produce positive eff ects, these are limited and fail to constitute a comprehensive strategic approach. Th e diff erent interpretations in the absence of a common defi nition as well as the strategies emerging from them are reviewed. Th e identifi cation of informa...

Modernizing Our Cognitive Model

Although still popular, the Observe-Orient-Decide-Act (OODA) Loop is outdated as a model of human cognition. Based on advances in the cognitive sciences since the 1950s, the CritiqueExplore-Compare-Adapt (CECA) Loop is proposed as a better descriptive model. The model puts two mental representations, the conceptual model established through operational planning, and the situation model, which r...
