IFR Cancellation Question

IFR would be then cancelled once wheels touch ground???


ATC takes no overt action to cancel an IFR aircraft landing at a
towered field. You just land.


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

ATC as in approach takes no overt action. The tower controller hits the
land line to approach and says "N12345 is on the ground" end of IFR flight.

He does no such thing. No calls, whatsoever. There's no need to.

I've been in a tower cab when this happened. I've also been there when
they've hit the button, called the tracon and gotten a release.

Were they special occasions? I don't know I don't spend a lot of time
visiting.

Explain how it happens at your location.

When I worked at what is now a class D it happens as I said. Airplane
lands and I tell him to contact ground control. No calls to the
facility that was our approach control. There was no need to. For
releases it depends on what you have worked out with your approach
control. At that facility we had to call for each release. There could
just as easily have been a letter of agreement allowing me to release
IFR aircraft on certain headings at my discretion. I work at a class C
now. The tower controller is, by definition, an approach controller
here. Everything is automatic. The only time you call for a release is
when you want to launch someone opposite direction and then only if you
are running standard procedures. Many of us just make a quick verbal
agreement between tower and approach that I as a tower controller can
launch aircraft anytime, anywhere and the approach controller will
accept them.

Are you saying that a telephone call isn't made or are
you saying that nobody in the tower closes the flight
plan?

Both. Nobody does anything.

What is so hard about this? When you cancel IFR inflight all
controllers down the line from whatever point you cancelled must be
notified that you have cancelled. This is normally done by the
computer, controllers receive a "remove strips" message for your
flight. When you land at a controlled field you're at the end of the
line. There are no controllers down the line to advise that you've
cancelled because you're at the end of the line.

Does the last computer to handle your IFR flight simply can it after
some time period has expired? I'm just curious what event removes the
last trace of my IFR flight from the ATC computers.

There is an anti-flight plan floating around in a parallel universe. When
your wheels touch the ground the two universes come into contact and the
flight plan and the anti-flight plan annihilate each other.

And a photon is emitted (either that or the end of the universe occurs).
