Just a note on shelves. We have on a number of occasions noted very bad behavior of AHRS systems - even those with very expensive gyros when mounted on shelves. Shelves tend to amplify vibration easily and this usually happens at very specific frequencies related to the physical dimensions and mass ...

No Spam attacks since you registered so no problem. Regarding fuel flow senders - basically all of them have what it termed "open collector" outputs. What this means it is effectively a simple switch with one end connected to ground and the other is your signal line. The switch opens and closes. The...

OK there is a workaround for the record number - on closer look OpenFlightMaps simply increases that number by one for every line. But since there are only 5 digits they start dropping the digits to the right of the number so the whole thing is meaningless. The workaround is luckily simple: Insert t...

I prepended the ARINC file with a fake header: HDR01TEST2001T 001T013200947692001 30-OCT-202006:17:37 ATM CORP CAI TEST_v17 B0268330 HDR02 And fixed the line endings to CR/LF - it then imports but the airspaces have a big issue which has to be fixed at whoever creates the source. Fixing line endings...

There is a problem related to record numbering in this ARINC data. Here is an example: SEURUREDRED-R 132 A 00100B G N48123000E008570000 GND 18000MR ED-R 132 A (HEUBERG) 111532310 SEURUREDRED-R 132 A 00110 G N48123000E009030000 111532310 SEURUREDRED-R 132 A 00120 G N48123000E009060000 111532310 SEURU...

Downloaded some of the ARINC data from OpenFlightMaps (Germany) to see what the issue is. These files look like they contain ARINC424 data but they are missing the header - the first line or lines should start with HDR and contain header information. This details things such as the originator of the...

Importing the image tiles using Mapmaker2 works great for raster maps. Maps look good. Have not tried their ARINC data - not sure what is in there. We use the ARINC import for several sources (FAA, Jeppesen, Russian data (not anymore), Airmate). BTW, we have been working with Airmate for some time a...

We found that standard countersunk M3 (Metric) solid brass screws have just the right properties - shears clean at about 10Nm (on outer hole) and does not suffer from fatigue. Avoid mild steel screws. Stainless steel can be considered but not as good as brass. Make sure your screw is solid brass and...

I have been forced to delete all inactive users due to a massive attack resulting in some 25000 bogus users in the database. Inactive users are those that registered but never posted. If you are one of them, you registered but never posted your details would have been purged from the database and yo...

Could this new “MX2” be a drop in replacement for an MX1 without installing any other components? Yes but some minor rewiring would be required - I cleaned up the pin allocations on the DB25 connector to group things and make best possible use of the connector. The only pins that are still the same...
