- The SIVOR project, currently being developed by ITA and Embraer, consists of designing andimplementing a high fidelity flight simulator based on the use of COTS industrial robots. The aim of theproject is to provide a cost-efficient and flexible platform that can be used along the design phases of theaircraft. One of the advantages of an industrial robot over the traditional Stewart platform is theavailability of a large workspace, which provides more flexibility for defining the washout filter. Thisfilter converts the aircraft dynamics into robot movements, which has a limited workspace. The mainpurpose of the flight simulator is to provide a motion feeling similar to the one imposed by the aircraftmovements in a real flight. The representativeness of the motion cue is usually evaluated in a qualitativeway by the pilots that fly the simulator. Quantitative methods to evaluate the entire range of actuation of asimulator are complex, inducing tests in fractions of the flight to increase performance. In this work, wediscuss the use of FOQA (Flight Operational Quality Assurance) as an additional quantitative tool for theevaluation of the motion cue in the SIVOR flight simulator. FOQA is a voluntary safety program fromFAA, detailed in AC-120-82. It proposes a set of parameters that can be used by airliners to analyse flightsafety and increase operational efficiency. The verification of FOQA parameters checks whether or notthe pilot complies with the standard operational procedures defined by the airliners and aircraftmanufacturers. The purpose of this work is to analyse whether or not, and to what extent, the FOQAparameters can be used to evaluate the quality of the motion cue of flight simulators. For this purpose, wedefine an experimental procedure that compares flights performed by pilots under different motionmodes. It then calculates a set of behavioural parameters that has been proposed in order to quantify howthe motion affects the inputs of the pilot. The results are submitted to ANOVA statistical analysis thatverifies the relevance of the motion factor. Finally, we discuss the capability of a FOQA basedexperiment to estimate the contribution of the motion to the realism of the flight simulation.

Experimental evaluation of the contribution of adding a motion system to an EDS

- The use of flight simulators in pilot training campaigns has become a cheaper and saferalternative to the use of a real aircraft, as simulators will not cause any kind of humaninjury or vehicular damages. However, the degree of fidelity of the simulation is of theutmost importance for this application, thus it has become the subject of discussion inseveral studies.It is understood as a flight simulator with a high degree of fidelity, all kind of simulatorsthat are capable of providing motion cues that are sufficiently similar to those obtainedduring an actual flight, so much so that a human would be incapable of noticing anydifference (Giordano et al., 2010). Many argue that the only way to obtain such a highquality of simulation is by using a motion platform, which makes the cost of thisequipment the same order of magnitude of a real aircraft.Several recent studies have contributed in this topic of discussion, the influence of themotion platform is still unclear (McCauley, 2006), (Proctor, Bauer and Lucario, 2007),(McDaniel, Scott and Browning, 1983). Bürki-cohen, Sparko and Bellman (2011) madea thorough review of the need of motion platforms in aircraft simulators while discussesthe need of motion platforms in military helicopter simulators, butThe objective of this work is to analyze the contribution of adding a motion system to anEDS (Engineering Development System), yielding a flexible and reconfigurablesimulator, available as soon as the official aerodynamic databank is made available. Theadvantage (if any) of creating an EDS with motion platform is that it brings to the aircraftdevelopment cycle, the opportunity of anticipating the knowledge acquired in thelearning-by-using approach, by means of a simulation environment that resembles thebehavior of the final product, especially in the early development phases.
