GEN II PC Simulator
This Windows-based simulator allows pilots to operate a virtual FRDS GEN II firegate installed on a AT-802F on a PC. This is great training for new SEAT pilots and is just downright FUN. The simulator is a free download.
Whether you already own an FRDS GEN II, or you’re just considering an upgrade to the FRDS GEN II, you should check out the app. You’ll be amazed at how simple operating the world’s premier fire gate truly is.
You can find the download file and program documentation in our Documentation section under Documents/Product Documentation/FRDS GEN II Documentation titled 5751-0050-FRDS-Sim-Installer.exe.
Functions
This simulator shows how the controls are used to set up and perform the recommended dumping operation. The tutorial and the simulator are NOT a substitute for pilot training. Pilots should receive formal training on an actual system before conducting live fire fighting operations. Trotter Controls, Inc. accepts no liability arising from any discrepancies between the simulator and the actual FRDS system.
STARTING THE SIMULATOR
When FRDS simulator starts, you’ll see two following screens. The right hand screen represents the cockpit controls of the FRDS Gen II. The left hand screen shows a gate animation together with some other displays and controls used in the simulation. The “Fire” and “Manual Salvo” buttons as well as the “Emergency Dump Lever” are simple representations of the controls in the aircraft. The gauges, screen and annunciator panel are for simulation purposes only and do not form part of an FRDS Gen II installation.
Note: the simulator displays will open “Always on Top” of any other applications you may have open, and you will not be able to view these. To change this behaviour, uncheck “Always on top” from the File menu.
The screen shows the FRDS system in powered off state. To start it, “turn” the key by clicking on the image. The FRDS screen will briefly show two initialization screens and will then power up. The system is not armed and hydraulic power is off. The hopper contains around 800 gallons of retardant. As in the real aircraft, the level will fluctuate as the contents of the hopper move around in flight.
SWITCH OPERATION
On the simulator, the switches are operated with a mouse. The ARMED and HYD POWER switches have two positions and are operated by clicking in the zones immediately above and below the switch. The mode switch has three positions, and so has three click zones. To select TIMER, it is easiest to click the switch itself. The YES/FOAM, LAMP TEST, and GATE switches have a spring loaded momentary action and will operate for as long the left mouse button is held down in the upper or lower click zones. The Datawheel also has three click zones. Clicking on the left arrow will decrease relevant values. Click the right arrow to increase values and the centerspot to change fields. The Contrast wheel has no function in the simulator.
DISPLAYS & CONTROLS
Most elements of this screen are self explanatory. The key feature is the LCD panel, which provides a graphical illustration of the dump pattern, depending on the values selected in the FRDS screen, as well as a “G” meter. The annunciator panel shows the dump outcome and allows the hopper to be re-filled at any time. It will illuminate in red when the hopper is empty. To operate the eDump lever, click and hold the button on the top of the stick and slide the mouse forwards slightly. To raise the lever, click on the handle and move the mouse slightly backwards.
PERFORMING A DUMP
The aim of this example sortie is drop 400 gallons of retardant with a coverage level of 1 gallon per 100 ft2. Assuming the simulator is powered on, select HYD POWER ON. Click the center of the Datawheel and the text “MAX” will be highlighted showing that this value will be adjusted. Click the left side of the wheel to reduce the value to 1.0 (gallons per 100 ft2 ). Now click the center of the Datawheel to highlight “PILOT” and adjust this to the value of 400.
You will notice that each time you change a value – either coverage or gallons to dump - the image on the graphical display on the left screen changes. We are performing an AUTO dump, in which the system will adjust the gates to maintain a constant flow. To see the difference between AUTO and TIMER mode, in which the gates open to a fixed angle, click the MODE switch in the center to change to TIMER, just for a moment. Because the gate angle is fixed, the coverage will vary according to the quantity of retardant remaining in the hopper.
Now, re-select AUTO mode by clicking in the zone above the switch. The graph will change to show constant coverage and the settings will be as previously selected. Try clicking the FIRE button. If you’ve followed these instructions correctly, nothing will happen, because the system is not yet armed. The LCD will remind you of this. Arm the FRDS by clicking in the top click zone of the ARMED switch. You’re ready to dump! So hit fire again.
Many things will happen quite quickly. First, the FRDS screen will change to show a dump in progress. Then the gates open to about 300 . Because this is an AUTO dump, the gates will continue to open as the dump progresses. Towards the end of the dump, the gate indicator will be indicating around 60o and the hopper quantity gauge will be showing half tanks. After that, you’ll have seen in the animation, the gates close and the display returns to normal.
Throughout an AUTO dump, the LCD screen tracks the coverage and groundline. The ball in the G meter will rise, indicating the +G forces the pilot will feel as the mass leaves the aircraft. Initially, the ARMED label and the AUTO ARMED light will flash to indicate a low pressure situation. The AUTO ARMED light will remain on once the pressure reaches 2600psi. The gallons to dump has changed to “ALL” because the quantity remaining in the hopper is less than the previously selected value.
Perform a second dump by clicking FIRE once more. Everything will work as previously, except that this dump will clear out the contents of the hopper. This will be indicated on the annunciator panel with a red “Hopper Empty” light. Clicking “Refill Hopper” restores the contents of the hopper and leaves all other settings the same, if you wish to repeat a particular scenario.
SLOW MOTION
Because everything can happen very quickly, the FRDS GEN II simulator has a slow motion facility, which can slow down some of the action. Click “100%” in the upper right corner of the FRDS window, and it will change to 50%, then with a further click 25% and then 10%, followed by 100% once more. This will slow the simulator down so that the changes are more easily visible.
To examine the screen in detail, the simulator can also be paused by clicking the “Pause” icon. A further click restarts. The “Running” indicator changes accordingly.
Note: Excessive use of these features are not recommended, because the simulator is not then representative of the real situation.
PANIC BUTTON
If you get stuck in a particular scenario, the “Reset” button restores the simulator to a default state.
