Flying with LX Eos
To get the best out of the LX Eos, it is important that some preparation is done prior to the flight
–
trying to
configure the instrument or set up a task while flying the glider may spoil your whole day! Preflight
preparation will ensure that the flight will be both successful and enjoyable.
22.1
Flight preparation on ground
- Check if you have desired TP data base uploaded.
- Prepare a task.
- Enter flight recorder information (pilot name, surname, glider type, recording interval
…).
22.1.1
Before take off
- Switch the unit ON at least 3 minutes
before take-off (this will ensure sufficient GPS reception and will
create a base line of the baro trace).
- Select correct pilot
(many settings belongs to pilot) on initial setup or create new.
- Check task if it is correct after using of Task stup
.
- The actual task during take-off will be declared
in flight recorder automotically.
22.2
During flight
The LX Eos HW and SW concept is so far optimized that the pilot doesn’t spend too much time to operate
the unit during flight. A very significant indication that shows
that the unit has changed to flying mode is
Logbook replacement with statistics page.
22.2.1
Set QNH
The pilot should input actual QNH value of the airport where he will take-off. This action should be carried
out on ground, after take-off, change of QNH in Setup/QNH Res menu will adjust altitude reading to actual
QNH setting.
22.2.2
Wind calculation
LX Eos is able to measure wind under two different methods. Wind calculation results are shown on main
vario page and on thermal assistant page. LX Eos will switch between straight and circling method
automatically and history of wind will be counted in new measurements.
Circling
:
Calculation
is based on ground speed (GS) oscillation due to wind influence in circling. The method is active
exclusively during climbing process. The process start automatically after circling is detected. The method is
based on fact that the ground speed is affected by wind. GS is maximal by tailwind and minimal by head
wind. This phenomenon is used by GS difference calculation method.
Straight flight:
On straight flight, wind will be calculated with use of iterative method which is based on IAS, GS and TRK
measurements.
22.2.3
Influence of wind in final glide
The actual wind data (speed and direction) influences the final glide calculation. In task mode the final glide
indication is based on remaining distance over all TP until finish (not over already flown turn points). Wind
influence for individual legs is based on current wind data.
