“…Examples of parametrisation results from these equations are given in Table 1 for four different examples. These were obtained using Equations (1)- (6) and clearly show (as expected) that, in the case of a steady turn at constant altitude: (a) airspeed does not change load factor but increases turn radius, (b) increasing allowable load factor leads to higher bank angles and higher heading change rates:…”

“…In that sense, the impact of pilot experience on results must be understood prior to any simulation. Note that it is recommended to use only few pilots (sometimes only one) in cases where experiments are still undergoing maturation [6]. The specification of performance standards, number of repetition, and overall length of the test are also influential parameters which have to be discussed: repetition for instance should not be considered for failure scenarios [39], and analysis involving pilot fatigue or adaptation should, on the contrary, consider repetition as an influential parameter.…”

“…Aircraft handling qualities were widely misunderstood at the early stages of aviation [5][6][7][8]. Pilot hands-on flight experience did not match theoretical predictions and understanding of desirable aircraft manoeuvrability derived from the equations of motion [9] and what theoreticians understood as desirable aircraft manoeuvrability.…”

“…Finally, and to cope with changes in design and operational use of a variety of aircraft, an evaluation of multiple representative vehicles was made still using pilot opinions and feedback [19] in an attempt to unify the methods and conclusions of handling qualities work. The reader is referred to excellent summaries of historical development and progress into static and dynamic stability theories (central to early methodical research efforts to understand and limit undesired behaviours) [5][6][7] for more in depth reading.…”

Development of a Multi-Directional Manoeuvre for Unified Handling Qualities Investigation

A slalom and alignment tracking manoeuvre was developed for multi-directional handling qualities analysis of large transport aircraft in simulation environments. The manoeuvre is defined and scaled as a function of aircraft characteristics, flight conditions using a simple set of mathematical models. Throughout the manoeuvre, the trajectory and overall performances are monitored at a set of gross position and alignment control checkpoints methodically distributed and sized to buoy the task and allow handling qualities analysis based on Cooper Harper Ratings and quantitative data analysis. Initial tests have shown that the manoeuvre sizing method led to feasible manoeuvres at multiple points of the flight envelope of a large civil transport aircraft. The manoeuvre capability to highlight desirable and undesirable handling qualities was also highlighted based on the initial findings for a couple of commercial large transport aircraft, a high aspect ratio wing and in-flight folding wingtip aircraft concepts. The relevance and applicability of the manoeuvre for multi-directional studies are discussed and compared against a more conventional offset landing manoeuvre. Finally, the potential use of the manoeuvre for different aircraft type and test flight is also suggested based on augmented reality technology.

“…The engineering analysis/analytical framework from which to evaluate these data, technologies and their resulting influence on the pilot is provided by the pilot-vehicle dynamic system, 28 is shown in Figure 4. This diagram identifies the influencing factors and characteristics that "govern the ease and precision with which a pilot performs the tasks required in support of an aircraft role."…”

NASA's Aviation Safety Program, Synthetic Vision Systems Project is conducting research in advanced flight deck concepts, such as Synthetic/Enhanced Vision Systems (S/EVS), for commercial and business aircraft. An emerging thrust in this activity is the development of spatially-integrated, large field-of-regard information display systems. Headworn or helmet-mounted display systems are being proposed as one method in which to meet this objective. System delays or latencies inherent to spatially-integrated, head-worn displays critically influence the display utility, usability, and acceptability. Research results from three different, yet similar technical areas -flight control, flight simulation, and virtual reality -are collectively assembled in this paper to create a global perspective of delay or latency effects in headworn or helmet-mounted display systems. Consistent definitions and measurement techniques are proposed herein for universal application and latency requirements for Head-Worn Display S/EVS applications are drafted. Future research areas are defined.

Eye tracking is the process of measuring either the point of gaze (where one is looking) or the motion of an eye relative to the head. This paper investigated use of eye gaze trackers in military aviation environment to automatically estimate pilot’s cognitive load from ocular parameters. We used a fixed base variable stability flight simulator with longitudinal tracking task and collected data from 14 military pilots. In a second study, we undertook three test flights with a BAES Hawk Trainer aircraft doing air to ground attack training missions and constant G level turn maneuvers up to +5G. Our study found that ocular parameters like rate of fixation is significantly different in different flying conditions and significantly correlate with altitude gradient during air to ground dive training task, normal load factor (G) of the aircraft during constant G level turn maneuvers and pilot’s control inceptor and tracking error in simulation tasks. Results from our studies can be used for real time estimation of pilots’ cognitive load, providing suitable warnings and alerts to the pilot in cockpit and training of military pilots on cognitive load management during operational missions.
