Avgas and fanta(stic pilot obviously) : dont have the regs on me, but does Pilots shall broadcast thier intentions to join a five mile final straight in approach as close as practical to 15nm ring a bell?
Yes it does. But, last time I checked when you say "***### is 5 mile final RWY XX" that actually meant that you were on a 5nm Final. Much like when you call ***### is downwind RWY XX, it is normally expected that the aircraft might actually be inside the CTAF.
