Though you may have another aircraft with a UNS FMS, please be aware, this one doesn't work the same way.

To use it effectively please follow these simple rules. Doing anything else will simply break it...

To fly using the FMS...

Set up your flightplan in the FMS
Turn on autopilot
Click the FMS button so that "FMS" is displayed
Click on LNAV button to engage FMS steering
Do not touch anything until you are ready to resume manual flying

I did precisely that and it flew the first few vectors following the flight plan, then all of a sudden with LNAV, FMS, all showing the green indicator, and the AP engaged, it just veered off to the right on a course of its own. Even deleting waypoints ahead of the next waypoint and re-engaging LNAV again after using HDG to put it back on track did not help. I had to fly the remainder of the route monitoring the EFB map follower manually. It does not level out at the selected ALT too. I have to engage ALT HLD to stop it climbing beyond the pre-set ALT.

Your waypoints are too close together.

Altitude Pre-Select does what it's supposed to do. You must engage ALT HLD however for it to do its job...

Let me get a handle on this. So, even after pre-selecting Altitude in that display unit next to the FMS, I have to also select ALT HLD to stop it shooting past that pre-selected altitude?

Thanks for that. So, even if the flightplan was generated by a flight planner such a Aivalasoft's EFB, I still have to delete waypoints that are too close to each other and it will then follow the FMS+ LNAV combination?

I'll give that a shot.

Question - how to enter the SID or STAR number greater than 99? For example, from LFPO I need SID103?

EFB is not a flight planner and even if it was, real planners also need corrections sometimes.

It isn't?? I use it to choose Departure/Destinations, routing, altitudes, SIDs and STARS, approaches, etc.
What else does a real flight planner do?
I stopped using Flight Sim Commander in favor of EFB thinking EFB would be better. Am I missing something?

Ihope we will have the sp1 soon because for my and a folloew all the the step to engage the fms and thats never work for me....

That's a bit strange because it actually does work. Just for some it can cause a ctd.

i don't had the lastest hot fix...do you thinks thats the reason?...

Possibly. WhAts it doing?

i follow the route in the beginning and during the flight the plane beginning to turn right i have lot of space between legs...so i finish the flight with the hdg...i had no problem the follow the route with the gps only with the fms...a follow too the instruction you write to engaged the lnav fms and autopilot...you are base in montreal just come in Quebec City i will show you what happen ...

Funny guy. Install the hotfix.
