No. When you get the Clearance you are IFR and bound by all IFR rules. At
our airport (WVI) when we ask for clearance to the SNS VOR stating that it
is for "climb to VFR conditions" we will be able to get that clearance as a
"pop up" clearance since NorCal (Sierra, Monterey ?) approach will keep us
in their airspace. They will expect us to cancel IFR when we break through
the tops. If we want a clearance to our destination and it is outside the
sector then we can expect to wait 15-30mins while the request is processed.

and will continue VFR once through the layer.
Receiving a clearance for ...on top while on an IFR flight would not
cancel the already filed IFR flight plan since the flight is to be
conducted under IFR rules (just on top).

I hope I worded this well enough to make sense to someone other than
myself.

This was for a clearance to a VFR flight in progress wanting a
clearance through a layer and continued flight VFR. Your statements
are true for ground initiation, but this is for somethong already in
progress, therefore the flight will be bound by IFR rules from the
time cleared 'till the time on top.

I was trying to correct a previous statement. This may help sort it
out:

What are you supposed to do if you don't break out of the clouds, and you lose comm?

as a

See earlier posts. Here at WVI I am talking about a summer fog layer with
the tops always below 3000 ft and usually the nearest clouds in afternoon
convective activity over the Sierras 150NM away. As another poster mentioned
this (almost daily) fog from June to Oct. must be somewhat an anomaly. I
jokingly refer to my IFR ticket as my "fog license". The nice thing about
fog is the smooth, predictable tops. The bad thing is the irregular,
unpredictable ceiling.

That brings up the age old question about following procedure vs. using
judgment. For example, if I've just departed ELM for say BOS and lose
comm on climbout, procedure would have me fly to BOS, assuming I don't
encounter VMC along the way. However, if I know that I have minimums or
better at ELM, I'd be inclined to shoot an approach there and get back
on the ground at my home drome and not be in the system for 1.5 hours
and flying into a fairly busy airport NORDO. I'd also think you ATC
folks would rather I do that as well, but I suspect that if anything at
all went wrong while doing this, the FAA would be likely to bust me for
not following the prescribed procedure.

I'm assuming that a successful outcome could be justified using the
"good judgment" clause referenced above, however, it does suggest that
good judgment only comes into play for cases NOT covered by the procedures.

I would explain that I had a complete communications failure for unknown
reasons and that while my navigational radios were functioning, I wasn't
sure how long they would continue to do so. To avoid a possible loss of
navigational capability in IMC I used the emergency authority granted me by
FAR 91.3 to deviate from FAR 91.185.
