ok, here we go...
i found the following info at the airnav site...

WX ASOS at MPO (20 nm SE): 120.275 (570-839-1584)
note that the last line says that weather (WX ASOS) comes from airport MPO (KMPO) located 20 nm to the southeast... i tuned the UFO's COM1 to the given freq and was able to pick up the weather data... it closely matched the METAR for KAVP... apparently KAVP does not have live ATIS/ASOS and uses the KMPO station for this information...
IF ATIS is available at KAVP, it will be given on the ATIS freq when tuned on one of the NAV radios... not a COM radio... i did try this but didn't get anything on that freq...
additionally, it seems that airports without a 50 line in apt.dat, like KAVP, only need that line added IF they do support ATIS... i'm not sure if there is any other data needed to be added anywhere, though... my above about defaults.atis and defaults.tower are misleading and should be ignored... apparently those files are no longer used... at least several devs have expressed that since i wrote it...
"You get more air close to the ground," said Angalo. "I read that in a book. You get lots of air low down, and not much when you go up."
"Why not?" said Gurder.
"Dunno. It's frightened of heights, I guess."
