Portable D-ATIS
I cannot help thinking that the technology required to recieve a D-ATIS would fit in a smartphone, or at least in a box the size of a Garmin 296. I would give up the other ACARS features as probably more demanding technologically, but I think just the D-ATIS would have several advantages: no missing ATC calls (or interrupting intercom chat), no misunderstanding of ATIS contents and not having to write it down. But does such a box exist?
