I am doing some preliminary work on approaches in my area on the sim. I load them up from the Garmin 430 on the sim. I also down load a copy from AOPA and print them out. The VOR RWY 27 gives I think a right procedure turn to 133 deg. The Garmin flew it to the left. Did I miss something or is the Sim Garmin just not up to date? I used the Hibbing procedure.

I just ran the EVM VOR 27 approach in GPS mode and VLOC mode on my 430 sim and it does not enter the PT automatically. I had to switch to HDG mode to make the turn in both cases. After the PT was completed it did give me the next DTK of 268 and resumed auto tracking. The PT is depicted on the display as a right turn entry 133 degrees as shown on the approach plate. The sim navdata date is 2/16/06 on mine. Software version is 5.01 .
 
The Garmin 430 does not repeat not fly PT's or holding patterns. If left to its own devices, it will, when it crosses the fix, turn in the shortest direction back to the fix, and 50/50 that's going to be on the unprotected side (nonholding or away from the barb). Therefore, if you're flying a PT, you must shift the a/p to HDG mode when you're ready to leave the outbound radial for the PT and fly it through the outbound PT leg and inbound turn via the heading bug before reengaging the NAV mode to reintercept the inbound course.

Ditto HP's -- you must go to HDG for the oubound turn, outbound leg, and starting the inbound turn. Once you have the nose pointed back towards the inbound leg, you can reengage NAV on the a/p and it will intercept the inbound leg back to the fix. If you're flying a HPILPT and will depart the fix inbound to the runway upon the second crossing of the fix, you can leave it in NAV. If you are remaining in the HP, you must reselect HDG mode once again to fly the oubound turn, outbound leg, and starting the inbound turn back to the fix.

I was using a 430 (SimFlyer) in MS 2004 flight sim. It was depicted as a left turn. That is the reason I asked. It must just be wrong in the data. The real 430 will not do all the turns but the 430 I have in MS 2004 will turn them all automatic and the hold. The first time through I just let the auto pilot do the approach to make sure that I am practicing it correct. This one just through me for loop because I was pretty sure I was correct.

Ron I will try clicking off the auto pilot and starting the turn to the right and see if the auto pilot can recover. I did notice that when it went into a hold it turned the wrong way also.

You've hit on another reason I don't like my trainees using noncertified software like MSFS to learn these systems -- they often lack fidelity, and the result is negative training transfer.

That is a good point. It did however make me work at understanding it and doing research to make sure that the plate was correct. If I study my approved plates and know in advance how I think they should go, I should be able to find any mistakes that the sim makes. At the very least it should open up questions for me. I plan on going over all the approaches with my CFI. I just can not get in the air at the moment. Winter in WI and all.
