How to Engage NAV and Acquire the Track

[Wink207 78]

Hi All:

I made my first hop today with the Falcon and generally all went well with one exception. I loaded in the flight plan without issue in the CDU and I at least thought it was in order but when I tried to transition from AP/HDG/V/S climb to LNAV, I could not convince the A/P to transition from HDG to NAV. After maneuvering so that I was on the desired track line on HDG, pushing the NAV button rendered no change except the HDG light in the PFD extinguished but a "NAV" or "GPS" light did not appear. So the A/P did not transition to LNAV. Could someone please suggest how I should procede? I read through the short Proline manual with the install and I'm pretty sure I loaded in the FP ok. I also noted a previous OP mentioned Direct To not useful to acquire the desired track. I did try that Direct To none the less in an attempt to acquire the track, but that did not change anything. The A/P would not acquire the track.

Thoughts please?

Thanks

Rick

Have you selected the FMS as your Nav source?   On your left PFD, under the speed tape it will either display VOR1, VOR2 or FMS for your Nav source.   Make sure that is shows FMS, otherwise it will look for your VOR1 or VOR2, which ever one is showing.    In order to change the Nav source, just to the right of your master caution lights on your glareshield  look for a square button labeled Nav/Brg.  It will be just to the right of the Baro knob.   Push the button, and then look to the far left PFD, a blue bordered box named " Nav Source " will open.  FMS will be on top followed by VOR1 and VOR2.   To cycle through these rotate the Menu Advance knob which is located just to the right of the Nav/Brg button on the glare shield.  (Menu advance is the inner knob)   You should then be able to cycle through the three nav sources.    If you want to follow your Nav radio  make sure you go back and choose the correct Nav source that you programmed your frequency for.    Hope it helps,

Matt

Thanks Matt. That helps a lot. The whole thing is very counter intuitive and the manual provides little help. I will say that one can make the Proline work, but it is not easy, and the aircraft handles very nicely in your hand. Once one figures out how to link the A/P to the FMS, as you described, then the next thing is how to make changes to a flight plan underway. Working on that.

Thanks again,

Rick

You're welcome Rick.   Have been doing some test flights with it, so far it's performing pretty well, it hit all of the altitude restrictions I had programmed in my flight plan .  Still figuring some things out, but overall happy with it.
