Do NOT attempt to load any data into the SN10! All software, firmware, waypoint and parameter updates are made by the glider steward! If you have any issues with the device, contact your local glider steward for a resolution.

In order to configure the device for SSA/FAI badges and state records look for a specific document that will be published. After it is published the document will be your guidance.

The ILEC SN10 and it's associated SN10B repeater is a widely used glider navigational flight computer. It is used for flight planning, flight monitoring, navigation, glide path prediction, igc file creation and a whole lot more. For an overview of the device, visit: ILEC SN10B

Electronic devices in the cockpit can be highly useful, and highly distractive. Educate yourself on the use of this instrument prior to attempting to use it in the cockpit! Distractions in the cockpit cause errors. Errors lead to accidents.

Practice with the SN10 simulator until you can operate it without a thought.
