Following an approach to runway 4 right at New York's John F. Kennedy International Airport, the airplane touched down about 4,700 ft (1,440 meters) beyond the threshold of the 8,400-foot (2,560-meter) runway and could not be stopped on the runway. The airplane was steered to the right to avoid the approach light pier at the departure end of the runway and came to rest in Thurston Basin, a tidal waterway located about 600 ft from the departure end of runway 4R.

The points listed are limited solely to commercial passen- ger aviation, but cover various independent topics such as the cabin, the aircraft systems, the airline and many more. The depth of the elaboration of the respective topic depends signifi- cantly on the complexity of the same. Depending on the situation, visualizations in the form of figures, tables and graphics are used, and the simplest basic physical-technical knowledge is required. The explanation takes place in a scientific-theoretical and nevertheless entertain- ing manner. In total, 13 curiosities are analysed and subsequently assessed. The individual points which this thesis deals with were selected in such a way that in practice they arouse in- terest, but in part also incomprehension, and are usually not self-explanatory.

Abstract The rising costs of air travel and the increased demand for consistent service has motivated providing avionicssystems which enableall-weather landing capability. All-weatherlanding can be at least partially accomplishedthrough provision of auto- maticlanding (autoland) systems andimproved landingaids such as the microwave land- ing system (MLS). The trend towardsincreased automation, together with increased equipment and maintenance costs, have motivated a rethinking of the potential role of the crew during automaticphases of flight. The problem,addressed in this study, con- cerns the waysan Independent Landing Monitor (ILM)may be used by the crew to comple- nent the autolandfunction. In particular, a systematicprocedure is devisedto es- tablishthe information and display requirements of an ILM during the landing phase of the flight.

  • Robust Autoland Design by Multi-Model H Synthesis with A
    aerospace Article Robust Autoland Design by Multi-Model H¥ Synthesis with a Focus on the Flare Phase Jean-Marc Biannic * and Clément Roos Systems & Information Processing Department, The French Aerospace Lab (ONERA), 31055 Toulouse, France; [email protected] * Correspondence: [email protected]; Tel.: +33-562-252-916 Received: 29 November 2017; Accepted: 7 February 2018; Published: 9 February 2018 Abstract: Recent advances in the resolution of multi-model and multi-objective control problems via non-smooth optimization are exploited to provide a novel methodology in the challenging context of autoland design. Based on the structured H¥ control framework, this paper focuses on the demanding flare phase under strong wind conditions and parametric uncertainties. More precisely, the objective is to control the vertical speed of the aircraft before touchdown while minimizing the impact of windshear, ground effects, and airspeed variations. The latter is indeed no longer controlled accurately during flare and strongly affected by wind. In addition, parametric uncertainties are to be considered when designing the control laws. To this purpose, extending previous results published by the authors in a conference paper, a specific multi-model strategy taking into account variations of mass and center-of-gravity location is considered. The methodology is illustrated on a realistic aircraft benchmark proposed by the authors, which is fully described in this paper and freely available from the SMAC (Systems Modeling Analysis & Control) toolbox website (http://w3.onera.fr/smac). Keywords: multi-objective H¥ control; multi-model design; flare control design; aircraft control; autoland systems 1. Introduction The steady growth of air traffic in recent years has led to drastic safety standards with the goal of limiting the number of accidents.
