Hi Ed - I do now have more info: I went in simulation mode as suggested and ran a flight from E38 east into the Laughlin One MOA (at 10,000 ft - the floor is 9000). It did NOT give me an alert. I do have MOAs set to alert with an alert button. HOWEVER, I then turned on "Other SUA" to alert with a button and now (under simulation) the Laughlin One MOA DID alert.
Hmmm...it really is an official MOA but seems it's treated as an other than MOA airspace. I have not yet tried an actual flight into the MOA with "other SUA" activated but I surmise it will act as it did in the simulation.
So to summarize, the alerts only recognize MOAs if "Other SUAs" is set to alert. It does not alert on MOAs if just "MOA's" is set to alert.
