Flight Recorder Operation
If you have selected any value other than OFF for REC INTERVAL, the Argus will
place values for latitude and longitude in a sequential block of memory. This memory
is sufficient to hold at least 3500 entries, which, depending upon the interval you have
selected, will hold from about 2 to 10 hours of flight data. The Argus does this
continuously as long as power is applied, regardless of speed, location, or altitude.
Recording is suspended when the Argus is in demo mode or being used as a dedicated
terminal. It also is suspended when you are viewing a previous flight and the second
DISPLAY LIMIT is not set to CURRENT.
The main consideration in selecting the interval is how long a record you wish to
maintain. Obviously, a 10-second interval will record 5 times as much flying time as
will a 2-second interval. A reason you might want to use the shorter intervals is if you
are doing a lot of maneuvering and wish to be able to view the fine details of your trip,
such as with IFR practice approaches. If you are doing cross-country flying, there is O*.
little reason to select the shorter intervals.
As mentioned above, the Argus will attempt to display data from the most recent
previous trip and the current trip. The "most recent previous trip" is determined by a
gap of 10 minutes in the flight record. Thus, if you take off for a $100 hamburger and
return, you will automatically see the trip to the present airport on the way home, but
should not see the record of any previous trips. A flight that is interrupted for less than
10 minutes is considered to be one trip, so brief refueling stops should not interrupt the
record. You can always manually extend the length of the assumed trip by adjusting
the START TIME on the flight recorder AMEND page.
You can also review any trip (or trips) as long as they are still present in the recorder's
memory. First adjust the START TIME to the beginning of the trip. Note that the
END TIME automatically tracks the START TIME so that one trip is bracketed. ^
Once you have selected the START TIME, you can move the cursor to the END
TIME and increase it to encompass as many past trips as you desire, until it reads
"CURRENT," which, of course, cannot be passed. When the "end time" is selected
to anything other than "current" no new points are recorded. This avoids possibly
