Really, then how does the system know you landed and not crashed on

The tower will know if you landed. What did you think happened?




I don't know how it happens, but the requirement is that they're
supposed to notice whether I have arrived at my destination not
whether I was handed off by approach. This means one of two
things:

1. Tower must tell the system that I've landed.
2. Tower must tell the system that I haven't landed.



The tower is "the system". At a tower without radar the approach
control will call on the landline and tell them about the IFR inbound.
At the agreed upon time/place the approach control tells the aircraft to
contact tower. Aircraft lands. Tower goes back to conversation on how
bad the Bears quarterback really is. The only time the tower calls the
approach control back is if something unusual happens. Aircraft never
calls tower at the expected time, aircraft has some kind of problem that
requires him to manuver unexpectedly thereby possibly affecting
separation of others inbound or outbound, etc. A normal approach and
landing is what's expected.
In a tower with radar all the above happens without a call on the
landline. The transfer of information is automated.

In the case of the nonradar tower, does the flight just "expire" in the
computer or does the approach controller kill the flight once the
hand-off to tower has been confirmed? If the pilot misses the approach
and then pops back to approach, do they have to enter the flight back
into the computer?
