6.  Background Information

6.1.  Memory Structure

The internal system memory of the VOLKSLOGGER is divided into three areas.

 

Flight Data Memory

 

Database Memory

 

Flight Registration Form Memory

Each area has special properties.  The individual access to the particular memory areas is
described in the following:

6.1.1.  Flight Data Memory

The most important  memory area is the flight data memory.  Here, all the information
received by the GPS or measured by the Altimeter as well as the information about the
instrument status, are stored in a variable recording interval.

Important Note:

The flight data memory is designed in such a way that 

the recording is stopped

 when the

upper memory limit is reached.
Therefore it is absolutely essential to 

clear the flight data memory before takeoff

(ACT.MEMCLR) 

or at least examine the available residual storage time 

(INF.MEM)

.

The dependence of the remaining storage time upon the selected storage interval is taken
into consideration during the display.  If one discovers during the flight, that the memory
might be full before the end of the flight, the residual recording time can be increased by
lengthening the storage-interval  

CFG1.LOG.INT

 during the flight.  However it is

necessary that this decision is made in a timely manner (and not three minutes before
reaching the capacity limit).

The memory contents can be read out with the different readout programs of the
manufacturer (DOS-readout software, Windows software) and stored on the hard-drive
of a PC.

Note:

During the clearing of the flight data memory, the contents of the flight declaration form
fields remain untouched and therefore can be used for declaring further flights even
after clearing the flight data.

6.1.2.  Database Memory

The integral database contains several sub-divisions.  Since this is a static database, the
maintenance of the database can be performed 

exclusively 

with

 

the PC-software shipped

with the unit; a change in the database, the addition or subtraction of way-points, routes
or pilots in the logger itself is not possible.
