Pilot weight is set in the Flight recorder menu (see Chapter 6.1.2).

For aircraft with flap, it is also recommended to enter flap position labels and speed range

for corresponded flap position. Speed range shall be given for reference wing load or

based on current wing loading and g-factor.

6.1.14 Profiles and Pilots

All settings and navigational page layouts are stored in a profile. Profiles can be used in

different ways:

 For club operation or multiple pilots sharing the same glider. Each pilot can have his

personal profile.

 When the user is flying a glider which can have a different wing spans. In this situation

the pilot has two profiles, one for each configuration.

 When a pilot is flying in several different locations. A separate profile for each location

can be created (examples: France, Spain, Namibia, WGC2014).

Profile consists of two parts:

 Navigational page layout defines which navboxes and symbols are visible on

navigational page. It defines colour of navboxes, font sizes and colours, how many

navigational pages are visible and which modes are enabled. Navigation page layout

can be setup with LX Styler or on device itself (See chapter 7).

 Device settings includes glider polar, selected databases, selected airspace and

waypoints file, map colours, vario indicator settings and flight computer properties.

Device settings can be modified on device itself through setup menu (See

chapter 6.1) or with LX Styler.

An active profile is selected when the system is powered on (see Chapter 8.1.2).

Use this dialogue to add a new profile, delete a profile, load/save a profile, copy device

settings, change name for an existing profile and to activate a profile. The active profile is

the profile which is currently being used. Select a profile using PAGE selector knob. Press

TO USB or TO SD for the profile will be stored to a USB stick or SD card. A profile is stored
