I've been flying around with the CRJ for a few months now, I've had no problems whatsoever. However, now for some reason I've run into some problems with position being off and as a result the LNAV not working. Example, I want to do a flight from CYRI to CYZV, which is a little under 200nm. I load up at CYRI, turn the IRS to NAV and input my init pos, no problem so far. I put in my route, select my departure/arrival info. That's when the problem starts, for some reason my initial fix keeps show at 4500 something NMs and as a result my LNAV doesn't work. I've attached a screen to show what I mean, this is really frustrating as it was working fine just a few days ago. Any help would be greatly appreciated
