Temporarily deviating from IFR

Danny Deger writes:

The call would be something like, "Request deviation 10 miles north of
course, altitude block of 2,000 to 3,000 feet and 3 360s to investegate a
possible car in distress." But, if the weather is VFR, "Cancel IFR" might
be the best call.

Can you reactivate an IFR flight plan after cancelling it and continue from
some point within the plan, or do you have to file a brand new one if you want
to return to IFR.

I take it there's no such thing as "suspend IFR."

What's it to you? You'll never fly.

You are correct. Once you cancel, you have to refile.

You are correct. Once you cancel, you have to refile.

If you are VMC and expect to remain so, you could request "VFR on top"
and a course deviation. If they don't have to hold a hard altitude for
you, they may be more flexible in granting deviations.

Certainly not in those words. There *is* such a thing as a compound
flight plan. This is used where you want to transition from IFR to VFR
or VFR to IFR at a certain point. However, the very few folks I know
who have ever tried to file such a thing have always run into problems
(controller doesn't understand, thing gets munged in the computer,
etc.). Usually easier to file TWO flight plans, one VFR and one IFR,
that swap off at some point. Or, more commonly, just request the change
in the air.

There is also a /D+xx that can be filed. It's used (at least in theory)
when you want to "suspend" the IFR flight for a few minutes at an
airport, usually to pick up or drop off a passenger. You file the route
something like CWK V17 TPL/D+15 V17 ACT where TPL is the Temple Texas
airport and you are going to be on the ground 15 minutes or less.

The problem is, it almost never works. Controllers have forgotten what
it means, and they don't like to have to keep the airspace sanitized
while you are on the ground. They would again much prefer you to simply
file TWO flight plans (in this case, one to TPL and one from TPL).

For the case you described that started this thread, the usual case is
simply to request deviations as needed. But IFR is really *not* for
sightseeing. [That's why airlines fly IFR always, now. They used to
always "sightsee" in good weather, until the day two of them ran into
each other over the Grand Canyon. After that the rules changed.]

You guys sure make this hard. The IFR system is not that rigid.

But there does seem to be a gulf between what is theoretically and formally
allowed and what actually works in practice.

Mxsmanic,

Not at all. It's all exactly the way it is in your game. No difference
between simulation and real life, remember?

The gulf I discussed applied entirely to real life, independent of any
simulation.

I was on a commercial flight years ago with an
active COM feed to the SLF headsets. Ours and
several other planes were picking their way through
a storm front and were continually requesting
10-20 degree right and left deviations to avoid
weather.
