Setting up your ILEC SN-10 Flight Computer

Software Version 2.2

Turn the SN-10 on. After the home screen automatically turns off, you might be on the “TASK” page. If not, rotate the page knob counter-clockwise until you are at the “left most” screen. This is the task page.

Turn the page knob clockwise. In the following order, you will see the moving map page, final glide page, thermal graph, wind, GPS, Alternates, Start/Finish, Summary, Calculator, and then the Vario Tuning page.

On the lower left hand corner of the Vario Tuning page, you will see either “FLIGHT” or SETUP.” You want SETUP, so move the cursor knob so FLIGHT is highlighted and rotate the value knob to change to the setup mode.

Turn the page knob clockwise one page to the right to the Audio Setup page.

The SN-10 can produce a variety of sounds, and you will want to try these in flight. Place the cursor on the top paragraph and turn the value knob to select different sounds.

Volume coefficient is how much the volume increases as you fly faster. You can change this volume so you can easily hear the audio at high speeds.

The SN-10 will give a useful beep, beep, beep “Lift Alert” sound when you enter an area of lift if you select “on.”

Turn the page knob one page to the right to the Variometers page.

On the Variometers page you select what the variometer indicators will show. You can choose Total Energy Variometer, Speed To Fly, 20 Second Averager, Thermal Averager, 20 Minute Climb Averager, Final Glide, Performance Index, Off, Relative, or finally, Netto.

If you have one ILEC variometer display, you probably want it to indicate Total Energy Variometer while climbing, and perhaps Relative Netto while cruising. If you have two variometer displays, one can read Total Energy Variometer at all times, while the other indicator might read 20 second averager while climbing and Relative Netto while cruising.

Turn the page knob clockwise one page to the “Units Page.” Here you select whatever units you prefer. Highlight each line with the cursor knob, then rotate the values knob to select the preferred unit.

After selecting your units, turn the page knob clockwise one page to the “Site page.” The SN-10 has storage space for two sites. It is common to keep your home site in one site and use the other for sites you visit. Before loading a new site data base, you must erase the location. A data base for many soaring sites are available from the SSA web site.

Turn the page knob clockwise one page to the right to the “Point edit” page. You can easily change turnpoint, airport or landing point data on this page. For major changes to lots of items it is easiest to use a computer program such as StrePla to develop or manage data bases.

Turn the page knob clockwise one page to the right to the Glider Polar page. Place the cursor on the glider type and rotate the value knob to select from glider types supplied in the ILEC database. You should also adjust the empty weight including pilot and equipment.

Turn the page knob clockwise one page to the right to the Airspeed calibration page. It is seldom adjustments need to be made here. If a reputable testing facility develops different data for your glider, you can make changes on this page.

Turn the page knob another click (one page) to select SN10 Options page.

Place the cursor on the square box next to “temp” and move the value knob to place an X in the box if you have connected the supplied outside air temperature sensor in the SN-10 wiring harness.

If you are using cameras rather than an IGC Data logger, place and X in the camera box.

Photo starts probably are not used anymore, however there is an option for this.

If you are flying a 2 place glider, you can adjust the rear seat screen contrast here.

Task type is explained below.

If your glider has an external flap switch or an external manual climb/cruise switch, select this option. You may optionally allow the SN-10 to automatically switch from climb to cruise by sensing G forces. To do this, place the cursor on “External Switch” and rotate the value knob one click to select “Automatic.”

If you have the SN-10 connected to a GPS engine, place the cursor on” GPS: None” and rotate the value knob to “GPS NMEA.”

You may select German language.

Finally, the lower right hand corner is where you select the task type. More below.

Turn the page knob clockwise one page to the right to the 2nd SN-10 setup page. You may select Club mode which limits the computer to a few simple pages, and also turn on a special Custom page where you can select items to be displayed. More on these later.

Turn the page knob clockwise one page to the right to the SN-10 resets page.

On this page you will set up the custom page and reload new software. More on this later.

Turn the page knob clockwise one page to the right to the “Raw sensor page.”

Adjustments can be made to the instrument, but it is rarely necessary.

Turn the page knob clockwise one page to the right to the Flight Recorder page. The bottom two lines allow you to enter your contest ID and name using the cursor and value knobs. Do this now.

More on this page later.

The final page is a simple final glide computer. You may use at any time.

OK, you have set up the basic settings of your ILEC SN-10.

Now it is time to fly. What do you want to do?

There are several choices: Competition mode.

Turn SN-10 on. Select the TASK page by turning the page knob counterclockwise to the most “left” page.

Turn the page knob clockwise 9 pages to the VARIO TUNING PAGE.

Turn the cursor knob until “Flight” in the left hand lower corner is highlighted. Turn the “VALUE” knob one click to change to the “setup” mode.

Turn the page knob clockwise 6 clicks (pages) to select SN10 Options page.

Turn the cursor knob until TASK is selected.  Here you can choose either competition or touring mode. Turn value knob until “Competition” is shown.

Move the cursor to the lower right hand corner of the screen where you may select from the following competition task choices: FAI, USA GPS, CLASSIC, or WGC99.

FAI tasks use sectors, USA GPS competition tasks use cylinders, Classic is when the pilot presses a “Mark Position” button to show a specific location, and WGC99 are European contest rules.

USA pilots will normally use either FAI or USA GPS.

Turn the page knob 4 clicks (pages) clockwise to the Flight Recorder page. Here you will designate the contest cylinder radius size. Move the cursor to “CYLINDER,” “FAI SECTOR,” or perhaps “NO NOTICE” and rotate the value knob to select “Cylinder” if you are flying a USA competition task, or “Sector” if you are flying a badge or record task.

If you select “cylinder,” move the cursor to the number to the right of “cylinder” to change the radius of the cylinder. At the time of this writing, the normal size is .25 statute miles.

If you select “sector” for badge and record flying, you do not need to designate the cylinder size.

On this page you may also select “Auto Start” by placing the cursor on the small box left of the words “autostart” and turning the value knob. It is normal to allow the SN-10 to automatically start recording when the glider begins to move.

Before flying a competition task:

If you are the only person using the SN-10 flight computer, you probably do not need to check every setting such as glider type, etc. If others may have made changes to settings, see the above instructions to check all settings before flying a competition task.
