5. Entering data from glider computer SR940:
If the recorder is connected to glider computer SR940 and if the SR940 is equipped with the correct
program version, data can be exchanged between recorder and SR940.
The SR940 has a special text page to communicate with the GP941; this text page has several sub-
menues:
The route selected on text page 11 of SR940 can be transferred to
GP941 as a declared task . This tranfer must be done before takeoff
to be valid. The turnpoints are selected on text page 11 only; selection
of turnpoints must be done according to FAI rules in this
sequence:
takeoff point, departure point, turnpoints, finish point, landing
point
. If takeoff point and departure point or finish point and landing
point are the same, the waypoint name must be entered twice each.
So an out and return flight consists of 5 waypoints.
The route cannot be programmed on this text page 21; however it is possible on this page to check
the correct sequence of waypoints by advancing the two digit leg number.
When a task is declared according to FAI rules, the day of the intended flight must be entered to-
gether with the task.
A task declared via SR940 is only valid for the same day
(the date visible on
text page 21).
If cursor is moved to NO and 1 is pressed, then YES is shown and the task is written into
GP941. Within the recorder the task data get a time and date stamp using the internal clock of GP941
to mark when the task was declared. At the same time the task is copied into the flight data.
After declaration of the task, the recorder and SR940 may be turned off. When power is applied again
to the recorder, the task data entered last are copied into the flight data record just when recording
starts.
A declared task can be changed as desired up to takeoff time; after takeoff it is still possible to enter
tasks but these declarations are unvalid, as the time of declaration is later than the takeoff time.
Attention: when recording starts, the task which is stored within the GP941 is written to the flight data
record. But if the task is old, the day of the intended flight will not be the day of the actual flight; so an
old task is unvalid.
The following submenues allow transfer of waypoint lists, routes and configuration data between
GP941 and SR940. When saving and restoring configuration sets it should be noticed, that sets no.
1...6 can be read to SR940 but only sets no. 1..3 can be saved from SR940 into GP941. So sets no.
4..6 cannot be overwritten by SR940, but sets 1..3 must be brought to 4..6 using a PC program like
WinGP.exe
