Report leaving 7000, assuming that was an assigned altitude. 5000 was never
assigned, so there's no need to report leaving it.


2) Its VMC and I'm IFR to Temple, level at 5000. At 25 miles out I report
Temple in sight. "N7NZ cleared visual approach to Temple, remain this
frequency til you're closer in". At this point I may descend at will,
right? When I do decide to descend, do I report leaving 5000?

Assuming 5000 was an assigned altitude, yes.


3) I'm level at 7000. "N7NZ, descend 3000 pilots discretion". Do I report
my descent? Can I level off at an intermediate altitude, and if so, do I
eventually report leaving that altitude?E.g. "leaving 7000 descending 5000"?
Then later "leaving 5000 descending 3000"?

Report leaving 7000, assuming it was an assigned altitude. You have discretion
to 3000, so you may stop at an intermediate altitude. No need to report leaving
altitudes that weren't assigned.


Please read the above "do I" as "am I required to". In my (small) IFR
experience to this point I have made the reports in many/all the above
cases, so I'm now trying to confirm which of them are unnecessary...
