We are now being asked to keep squawking C all the way to the ground.
This is per a recent document which I have read, remembered, but forgotten exactly what the document was.
The present and urgent requirement is to be able to submit a credible objection to GA (light) having to buy expensive mode S equipment.
I have yet to look at the AOPA link mentioned, but it would help if those that know post on this forum a credible arguement.
