I have absolutely no idea what you're talking about. The GP is literally about a lone controller in the tower having a medical episode and what would happen after that.
replyThe pilots would execute untowered approach procedures, a small airport with little to no traffic and VFR flight you may self-announce on frequency, a larger airport you go back to approach, etc.
replyEach of those flights should have an alternate and be prepared (have enough fuel) to divert. If there is a fuel emergency then self-announcing is likely appropriate as the plane is coming down anyway, but that is multiple things going wrong.
replyA big part of it is what category of airport it is, and plane. General aviation almost always goes to self-announce (which includes some business jets perhaps, they often land at untowered airports) but not category 135 air travel or whatever it is.
