look at it from the Avmed staff point of view; there is no “‘upside” for them in letting you fly. There is plenty of downside. They will automatically be blamed for letting you fly if you have an accident.
Their only defence is relying on the AAT and multiple specialists reports to diffuse the responsibility of letting you fly; such that they cannot be blamed.
They are on contracts so the easiest and safest thing for them is to say “no” to you.
This cannot change until the political pain of letting us fly freely is less than the political pain from preventing us from flying. We need (as I keep saying like a broken record) to create a lobbying body that is capable of inflicting great political pain on selected political targets. AOPA USA has such an attack dog. We need one too.
Unfortunately our potential attack dog was slipped a bait by the government and is no more.
