Preliminary Human-in-the-Loop Assessment of Procedures for Very-Closely-Spaced Parallel Runways

Demand in the future air transportation system concept is expected to double or triple by 2025 [1]. Increasing airport arrival rates will help meet the growing demand that could be met with additional runways but the expansion airports is met with environmental challenges for the surrounding communities when using current standards and procedures. Therefore, changes to airport operations can improve airport capacity without adding runways. Building additional runways between current ones, or moving them closer, is a potential solution to meeting the increasing demand, as addressed by the Terminal Area Capacity Enhancing Concept (TACEC). TACEC requires robust technologies and procedures that need to be tested such that operations are not compromised under instrument meteorological conditions. The reduction of runway spacing for independent simultaneous operations dramatically exacerbates the criticality of wake vortex incursion and the calculation of a safe and proper breakout maneuver. The study presented here developed guidelines for such operations by performing a real-time, human-in-the-loop simulation using precision navigation, autopilot-flown approaches, with the pilot monitoring aircraft spacing and the wake vortex safe zone during the approach

Trade unions and work-life balance: changing times in France and the UK?

The mixed empirical findings to date have indicated that some, but not all, unions in industrialized countries are actively involved in campaigning and bargaining around work–life balance (WLB) issues, as part of a modernization agenda linked to feminization and to ‘positive flexibility’. This article seeks to identify factors that might encourage or inhibit trade unions from involvement in WLB issues, within a cross-national comparative perspective focusing on two countries (France and the UK) that have contrasting working time regimes and approaches to WLB. It draws on original research carried out in two sectors — insurance and social work — in these two countries. The article links the emergence of union WLB programmes and bargaining agendas to genderequality concerns within the union and to the gender composition of the sector, as well as to the working time regime, including the mode of action, partnership being a significant corollary of WLB campaigning in the UK. We find support for the modernization thesis in the UK, particularly in the public sector, but within severe constraints defined by employer initiative
