I can't see AM on the aircraft bands being phased out any time soon
(voice anyway).

The readability of low signal level AM is better than FM.

Having said that, whether we'll get to the stage when voice comms wont
be needed, being superseded by data, I don't know.

Airinc has been pushing digital voice:

A bad idea of course, but there is this mentality that digital is
better than analog.
