The ability to create a completely immersive training environment relies on
the quality and integration of a simulator device's key technologies:
F2Si's strength lies in the ability to create and integrate technologies with variable complexity levels in order to deliver custom, quality, and cost effective solutions to any training need.
A completely immersive training environment demands the seamless cohesion of numerous, precisely replicated vehicle systems within a dynamic and detailed environment. F2Si has continued to prove its ability to produce and deliver simulator devices throughout the training industry in an affordable simulation package, customized for any training environment.
Advanced Simulation Training
Tomorrow's cockpit is here today, and it's a far cry from yesterday's “6-pack” instrument displays. Even for general aviation aircraft, Primary Flight Displays (PFDs), Multi-function Displays (MFDs), GPS, Mode S Transponders with TIS and other advanced avionics offer enhanced position awareness and safety but also present new training challenges. Aviation insurance underwriters will require that as much training as possible for Technically Advanced Aircraft take place in full motion simulation devices like the F2Si MOTUS.
The broad acceptance of TAA aircraft is even causing the FAA to rethink how primary flight training is conducted. Programs like FITS (FAA/Industry Training Standards) are providing a framework for flight training organizations to accelerate training in TAA aircraft by utilizing a variety of training tools, including simulation devices.
F2Si can provide a device with any of the various glass Avionics platforms. By using actual manufacturer's LRUs or digital simulations of the equipment, F2Si can meet the customer's needs and budget. Using the actual GDU displays and GMA audio panels from Garmin can offer the highest level of specificity, functionality and tactile feel. Updated firmware or ancillary options such as SVT or TAWS are fielded quickly when the real equipment is used.
To save costs and meet a restricted budget, digital simulations can provide the necessary training. F2Si has experience to meet the functionality of the PFD displays such as in the Universal 890R suite. The digital simulation of the PFD along with actual FMS components and replicated control panels offers the customer a lower cost solution without losing capability.
What does MOTUS mean? It is Latin for "motion".F2Si is unique in being able to offer full motion flight simulation at an economical price. The all-electric design of the MOTUS simulation device is extremely reliable and avoids all the maintenance headaches associated with older hydraulic designs. And unlike many other electric base designs, the motion itself is smooth and quiet.
F2Si is experienced in integrating industry leading motion seats to provide motion cueing for situation in which full motion base is not desired or impossible. Motion seats provide 6 Degrees of freedom while not moving the rest of the simulator.
6 Degrees of Freedom Motion Systems
F2Si's patented motion base interface flies like the real thing. Similar to Level D simulators costing tens of millions, the MOTUS simulation device includes "washout" and other techniques to provide the same vestibular cues found in actual flight. A "Disorient" function is also available to provide motion cues out-of-sync with the flight parameters, and drive the trainee to focus on the instruments.
In MOTUS devices, turbulence and wind shear are not theoretical phenomena. The turbulence function "loads" a pilot and provides a level of authenticity that is simply unavailable in fixed-base training devices.
There's never been a question as to whether motion cueing is desirable - only whether motion cueing is worth the rather significant additional cost. But the cost of the MOTUS simulation device is comparable to - or less than - an equivalent fixed-base design. Since pilots and insurance underwriters alike dramatically prefer full-motion flight simulation to training in static devices, MOTUS can uniquely drive the growth of a flight-training organization.

LCD Mosaic Wall™
F2Si’s high resolution LCD Mosaic Wall™ provides a detailed, wide-angle external view that greatly increases the utility of the simulation device. It provides higher pixel density per scene than other visual systems costing many times the price. Unlike lower-resolution projected displays, the highly detailed LCD Mosaic Wall provides the visual cues necessary to use MOTUS for a wide range of VFR maneuvers. The external display works perfectly in concert with the six-degree-of-freedom motion base to provide Total Flight Immersion. Each visual channel is driven by its own computer to ensure a 60 Hz frame rate with no stuttering.
MOTUS comes complete with a worldwide airport and topographical database. Pilots can train at any airport anywhere on earth. And the database is fully user-reconfigurable. If terrain or taxiways are not exactly as they are at the actual airport, they can easily be edited to match. Users can even add visual objects to the display, including buildings, dams, towers, and other detail, to enhance the training experience.
With some editing a plain and flat landscape can turn into a beautiful skyline full of visual references. The image to the left is the way the Toronto Buttonville airport is seen.
F2Si provided the customer a detail package that transformed the skyline into the images seen above.
F2Si is experienced in integrating projection systems, providing a wrap-around dome with a seamless image. In a recent simulator, a series of projectors, project an an accurately edge blended image across a fabric screen to provide a fully immersive 200 degree horizontal FOV by 60 degree vertical.
The Feel of Flying
With traditional flight training devices, only two of the pilot's five senses - sight and sound - are engaged. The F2Si MOTUS device takes this to a new level with its proprietary six-degree-of-freedom motion base, providing both the vestibular sensory input sensed by pilots in actual flight as well as the turbulence functions necessary to "load" a pilot for a realistic training session. But even then the pilot doesn't "feel" the aircraft in the flight controls. Dynamic Control Loading allows the pilot to incorporate fully many of the different "feel" aspects of flight training.
The change in required input to the flight controls depending on airspeed – for instance, as the airspeed decreases, correspondingly different control input will be required to cause a desired result.
In many rotorcraft and in some modern fixed-wing applications, force trim adjustment allows the pilot to place the flight controls in the desired state…and leave them. The controls maintain the position desired by the pilot.
Modern autopilot systems, particularly in helicopter simulation, move the cyclic in response to A/P commands.
Many regulatory standards (FAA & JAA) require a specified static and dynamic feel of the controls to achieve desired approval levels.
With the advent of "follow trim" in many aircraft, the dynamic control loader also has to be a subtle control positioner following the logic and resolution appropriate to the aircraft being simulated.
Lite or heavy: If it is a 150 pounds of force on the control column during boost off conditions or 3 pounds during normal flight conditions of a single engine piston, F2Si Flight Simulation has a solution
F2Si has developed great expertise in these and other areas relating to dynamic control loading. With this capability in addition to its six degree-of-freedom motion base and LCD Mosaic Wall™ external visual display, F2Si is closing the gap between inexpensive flight simulation devices and Letter-Level flight simulators costing millions more.
Aerodynamic & Physics Modeling
F2Si utilizes a number of industry tools and in-house expertise to craft and refine the model for each simulation device. Everything from the basic lift and drag characteristics of an airfoil, to the dynamic effect of downwash on a tail rotor are accounted for to present the trainee with real-to-life reactions to their control inputs that they'd experience in the authentic vehicle.
Data sourced from flight testing, manufacturer documentation, and industry partners provides the foundation to measure our flight models. Whether for an AATD or FTD, F2Si strives to provide complex aerodynamic and physics modeling in all levels of devices, regardless of certification. Traditionally low fidelity devices can now incorporate detailed physics and vehicle dynamics typical of elite, higher level devices, at a fraction of the cost.
Flexibility in design, and rapid data comparison to multiple sources allows F2Si to quickly prototype and refine physics models into quantifiably accurate simulations. Optional on F2Si simulation devices is the powerful Laminar Research PlaneMaker aerodynamic design utility, a Virtual Wind Tunnel that offers F2Si and its customers total control of flight dynamics for each aircraft.
The PlaneMaker aerodynamic design software is so realistic that Imperial College London and West Virginia University have both purchased F2Si's MOTUS simulation devices primarily as aerodynamic research tools.
With PlaneMaker, users can modify the flight model to meet end-user or regulatory standards. Consider for a moment the options if a flight model in an installed simulation device requires a small modification in climb performance, stall speed, or stability. Other providers could offer only an expensive upgrade after an extended delay. With MOTUS, users can easily modify flight model aerodynamic characteristics as necessary to meet their training requirements. Only MOTUS provides this added value.

Fluid Dynamics and Physics Modeling
F2Si offers experience in modeling maritime ballast control that utilizes industry practices to produce accurate physical responses. Vessel hydrostatic tables are imported for high resolution results for draft, metacentric heights, center of gravity, center of buoyancy, and center of flotation. This allows a full range of training – from simple pitch and roll responses to negative GM scenarios.
Environmental modeling extends this flexibility by offering realistic wave responses through rolling periods and free surface effects on all ballast tanks. Weather can be setup with custom scenarios or through single button clicks on the Beaufort scale.
Fluid dynamics of ballast piping offers realistic training scenarios by importing real oil rig tank tables. Valves can be opened to allow any number of tanks to be either free flow equalized or controlled via pumps. Air venting is simulated to enhance training of compressibility for holed tank scenarios.
External forces that are applied to maintain position can have a drastic effect on a maritime vessel. F2Si offers solutions for dynamic positioning systems as well as mooring systems. Mooring winch control panels allow additional students to cooperate with the ballast control operator in maintaining vessel stability. F2Si has incorporated sophisticated catenary physics to maintain both wet and dry chain/wire lengths and produce accurate torsional forces.
