Default Re: Why is aeronautical VHF AM?

No, it's not quite such a product of evil intent. The specs are written around what the receiver has to achieve, not how it has to do it. Sometimes this approach leaves you free to find a new technique other times it leaves you wondering how you can walk a knife-edge and sometimes wondering if they've asked something just on the impossible side.
