Purchase the Yaesu (Vertex) dual band aviation and 2-meters. It is
type accepted.

No. It's not legal and the aviation frequencies you are looking for
are HF, not VHF.

Although not legal, I've seen many an Icom set up for the aviation
bands for transoceanic flight.

There are several HF aviation bands and I don't have a copy of the AIM
here (not sure if it has them or not), but as I recall they are a bit
above 75, 40, and 20.
