Data Logging On G2-3-4-9

 

 

European Windows Warning

The standard field delimiter for CSV files is the comma. On American Windows versions, the comma is set as default for the "List Separator", which is okay for CSV files. But on European Windows versions this character is reserved as the Decimal Symbol and the "List Separator" is set by default to the semicolon. You will need to change the decimal symbol to a period and the list separator to a comma in control panel. I have a PDF document with step by step instructions on how to do this using Windows 7 Professional. On another version of windows the steps may not be identical but they should be similar.

Data Logging Perfected

 

Utilizing the old data log files was difficult because the information was lacking. Oh there were plenty of temperatures all right, but without parameters like altitude, and airspeed some error prone assumptions had to be made to put all the pieces together. The new G3/4 solves that problem. It incorporates not only its own measured data but data from the TAS-1000 air-data system and the GPS(Coming Soon). Adding ambient data to the file facilitates meaningful comparisons of one flight to another. Another key benefit of these extensive data files will be in processing them to create airplane specific performance charts.

 

Unlimited Storage for Free when we introduced the GEM 610 years ago 32 Kbytes was the largest available non-volatile memory chip. If ordinary techniques were used this is scarcely enough storage for an hour-long flight. Far from the 50-hour goal. At first it seemed an insurmountable limitation. Packing the instrument with dozens of expensive chips was impractical. A custom data compaction algorithm was developed that would pack more data in a small memory chip and shorten transmit time over the infrared interface. Luckily today none of this matters. Fueled by the digital camera revolution flash memory is so cheap it may as well be free. We chose the SD card for its widespread availability and low cost.
Fortunately the card is small enough fit in the tiny space below the display.
The card has a Windows compatible file system with Excel compatible files so you can read it without any special software. The cards have huge capacity, large enough to store engines entire life history.

Datalog files are automatically created and stored on the GEM's SD card each time the GEM starts up. All data measured and displayed by the GEM is automatically logged once per second except for vibration data. To log vibration sensor data, turn the GEM display to one of the vibration pages and press and hold the Page knob (PG) for a few seconds. This triggers the capture of one set (X,Y,Z) of the current vibration data and stores it in the current datalog.

Each flight's data is stored in an individual log file on the SD Card in CSV format (comma separated values). Every file has an identification header containing the date, time, and instrument configuration. The log file can be viewed and graphed using a word-processing or spread-sheet application, or one of the after-market datalog analyzer applications. See the vibration application notes on the Insight website for more information about vibration data.

SD Card

 

Data-logging with the G3 provides the benefits of long-term trend monitoring through a standardized personal computer interface. The G3 data-log system makes it easy to retrieve log data from all flights. The G3 automatically records parameters during every flight. Each flight's data is stored in an individual log file on the SD Card. Every file has an identification header containing the date, time, aircraft- registration and data log configuration. All data is sampled and recorded every one second of flight data allows up to 5,500 hours of flight log to be stored on on the SD Card. Data acquired with the G3 can be viewed directly in raw form, or imported into spreadsheet and database programs for graphical analysis.

 

G3

 

Enable the pilot/user to mark an event in the log file.

 

If during a flight the pilot notices something unusual, maybe a drop in one of the readings, he may want to closely examine the log file later. 

In order to make it easy for him to find the entry in file we need to provide a means for him to mark or tag a record in the file.

Implementation: In order to mark the event the user simply presses and holds the top button. 

The screen momentarily pauses and increments and displays a number assigned to this event. 

The first press generates a ‘1’, the fifteenth press generates a ‘15’ etc.
