I had a problem that if I added an approach mid-flight, the airplane would do a 180 and go back to the previous waypoint before starting on the approach.

I found a video that explain how you can work around this.

 

 

Thanks to Clumsy for the video.

You could try to just to hit "load and activate". But that's a problem.

It's a work-around,  temporary I'd add. This is an Asobo problem and seeing it's not on the road map, we're not likely to see a solution anytime soon. Our only hope is 3rd party developers and that could be a while.

 

There are dozens of threads/comments about this already. It's a bug, I doubt it will ever get fixed. 

The video isn't particularly helpful and overstates the problem. Seems like a "clumsy" solution. And I'm having my head buried in my MFD while rifling through waypoints. 

1. Load or Load and activate the procedure right after you pass the final waypoint before the iaf. Plane will do a 360 then continue on and will fly the approach without any issue or problems. Just tell your passengers you're flying a hold due to air traffic.

To avoid 180°, I delete all previous points in the Fpl (C172 old).

This is a known issue.  

It stems, in part, from the fact that ATC doesn't usually give you your approach information until after you pass the last waypoint prior to the start of the approach.

My work around is to add waypoints at the end of the flight plan so that if I get rerouted to the last waypoint, it's not as far to go.

If you go into the filters part of the flight planner and activate all the navaids, including the GPS and Fix data, you get a lot more points close to your destination that you can add to the flight plan you currently have in the editor.  

I had one flight plan where the last way point was over 100 miles behind me.  I had forgotten to follow my own advice.  So instead, I opted to synchronize the hdg bug and then fly the rest of the approach through the AP HDG mode until I was on final.

The other work around is to manually add the approach itself to the flight plan.  That way you can activate the approach before ATC gives it to you.

I think another option to, is add the "transition" in the flight plan.  That way you get the transition automatically added to the flight plan and it makes the approach seem to be less wayward.  

Those are just some things I've done with varying levels of success.  

But yes, it is broken.

That is well and good in that aircraft model with the Mod he points out that he has applied for the GPS.  Not nearly as easy in other aircraft, particularly with G1000 or GNS.

It is well documented now that in at least some MFS aircraft models you must activate the approach before reaching the last waypoint in the flight plan that precedes the first fix in the approach itself.  If not it will turn you around, fly you to that prior fix, and incredibly may continue flying your flight in reverse. perhaps all the way back to where you originated.  I let it continue like that through four prior waypoints one day before I quit the flight.

Here is an example.  If you are flying in to St Paul Downtown (STP), St Paul Minnesota, USA, from the south using the RNAV (GPS) 32 approach, the IAF or initial approach fix is LDASH.  Your last fix in your flight plan before LDASH is likely the VOR at FGT.  If you activate the approach before you reach FGT the G1000 will currently enunciate with a magenta bracket the approach segment from LDASH to the next approach fix FOMRU.  But it will first continue you to FGT, then pick up the approach.  No real issue.  If you wait until after FGT to activate the approach is when the issue occurs.

This is not true to real life and there is a posted question over on the MSFS forum for the September 30th developer Q&A session.  It is at this link: https://forums.flightsimulator.com/c/community/developer-q-a-questions/172.  I recommend if this is important to you that you go to the site, seek out the related question or questions, and vote.  That may escalate it in importance.

If you are flying without a flight plan, my suggestion is to load a published fix first and have it start you to it before loading the approach.  Then before you arrive at that fix, activate the approach.

I have had some success when turned back 180° by going into the PROC page and activating the approach a second time.  Just allow the #$%^^%$ G1000 to fly you past that prior fix first.
