Thanks! Keep forgetting there's a 'setup' on the main menu.
Quote:iNavX and MacENC use exact same code/logic for CPA/TCPCA calculation. Both require valid: COG and SOG of your vessel and valid SOG and COG of the AIS target to be computed.
Okay - so they should have been seeing the same data, given iNavX got its feed from the laptop which was hooked to the NMEA feed. We didn't spend long looking at it - we just popped inside to the laptop to check the CPA when we didn't see it on the iPad.
Will do some more exploration next time...
Cheers,
