When I work traffic into a non-towered airport, if I use "...frequency change approved." the target stays white and shows "1200", then the pilot responds appropriately followed by the target turning green.
 
When I use "...change to advisory frequency approved." the target immediately turns green with no reply from the pilot.

I use, "Radar service terminated, squawk one two zero zero, frequency change approved." Tbh, I don't recall any response from the pilot, target just turns green.

The AI pilot does respond and the target turns into a green "splat" with Mode-C readout. . .  *65 . . .

What you are doing with this command is handing the pilot off to a tower.  The tower is not under your control, which is one reason why you don't specify the tower frequency.  The pilot changes over to tower, and does not reply further to you.

In real life, and in the sim, you are actually terminating service with an aircraft that is landing at a non-towered airport.  There is no control tower at that field.  In the case of ABQ TRACON, ABQ and AEG are towered airports, hence the "contact tower, 120.3".  E98 Mid Valley and E80 Alexander have no control tower.  Planes operating at those airports use a Common Traffic Advisory Frequency (CTAF - pronounced "see-taff").

In my experience as a rw pilot, "frequency change approved" is used when terminating radar service mid-flight, such as class B or C service. The controller will usually say something like, "Cutlass 46D, leaving my airspace, radar service terminated, squawk 1200, frequency change approved." Often he may suggest the next controller, "You can try Jacksonville center on 134.0"
 
When approaching a non-towered airport to land then the "change to advisory frequency approved" is used.
 
In the sim, the former is handled normally, with the target going white splat and the pilot acknowledging the transmission then the target goes green splat. However, with the latter the target immediately goes to a green splat with no transmission from the pilot. This instruction should actually result in the same sequence as the former.

Further, in the case of the IFR flight landing at a non-towered airport, the aircraft should call back after landing to cancel IFR.

That's true. In this case, each aircraft had reported the airport in sight and been cleared for a visual approach. In the Sim, it's reasonable to assume they would cancel their IFR clearance in the air. In RL the controller would prompt them for the cancellation or instruct them to cancel with flight service on the ground. Without that cancellation, the field is closed to any more IFR arrivals until it's received by ATC.

Many times I've given the command, and they've read it back and gone VFR only A few minutes later they report entering the traffic pattern. Not a bug, I dont think, just interesting. Like the pilot just forgot to change his radio and thought he was on CTAF.

Also forgot to 'radar contact' someone, and a few minutes later they requesed flight following. That was kind if cool, since i never heard that before.
