If program version 2005 or later is loaded into SR940 and GP941 has version 2.04 or later, then the
name of the pilot can be written from SR940 to GP941. Up to three names are stored within SR940
and can be selected by number #1 to #3. Transfer of name should be done before takeoff, as this will
begin a new flight data file within GP941.
6. How to use GP941:
Here are some suggestions for pilots and competition organizers:
Flights during central competitions:
Before takeoff waypoints must be loaded into SR940 / SR920D. The coordinates of the waypoints
must be exactly those which are used for the given tasks. Use only waypoint lists provided by the
competition organizers!
Enter name, competition class and competition number into GP941.
Select the correct GPS alarm (Photo sector or circle) at glider computer SR940.
The recorder must be turned on in time before takeoff, so that GPS reception is already active before
takeoff.
In the air any point can be stored acurate by one second when the marker button is pressed. These
marks are in addition to the standard 4 second fix interval. Pressing the marker button also initiates a
sequence of 10 more measurements with 1 second interval.
If SR940 announces entering the photo sector or circle, an automatic mark signal is transmitted to the
recorder, which adds 10 additional fixes with 1 second interval to the recording. This automatic mark
signal is transmitted only once when entering the photo sector or circle.
After landing the recorder is turned off and is removed from the glider.The competition organizers will
read the flight data from the recorder and evaluate the flight.
Flights in a decentralised competition:
Before takeoff there should be done a written declaration signed by an official observer. This flight
declaration must contain:
date of the intended flight
full name of the pilot
type of glider, competition class, glider registration number
used GNSS flight data recorder: manufacturer, type, serial number
The declared task can be written on the same paper or the flight declaration is marked with task as
written into flight data recorder . If the task is done by writing then the task within the recorder should
