Err I don't think that's 100% correct but it will do for MX.

Please then for my benefit point me to such a regulation.

Technically speaking, it is illegal to descend faster than about 25,000fpm
(needs to be adjusted based on density, since it's give in terms of
indicated airspeed) when below 10,000ft. I doubt too many flights would
need to worry about this limitation.


You've got it! Also Vne is usually a lot slower than that for most GA.
There are other "tricky" examples I can think of.

Well, what if you exceeded the 250 knot limit going down in class E
below 1000?

Oh boy, would you be in trouble with the FAA then!

No, you can do it if ATC waive it. Happens all the time.

Certainly. Vne is a limit that must not be exceeded (there are
others). This sets a limit on how fast you can legally descend
(remember pilots must fly within operating limits). You must also not
use ascent or descent rate that put you in conflict with ATC unless
you have got clearance. When NORDO you cannot ascend or descend into
controlled space except as part of a flight plan. The descent rate at
or below 500' must be zero or negative except at an aerodrome or
within a LFZ. You can probably now see other examples. Pilots should
think outside the box ;-)

Actuall, that's "should not" There are airplanes in which it's permissable
to go to Vd in an emergency, though they might have Vmo instead of Vne now
I think about it.
I'm not even sure if I've flown one or not...

Never mind!

What? You believe that an aircraft with no radio is not allowed to
enter controlled airspace without being on a flight plan?

Can you please provide a reference to that regulation?

The descent rate at
or below 500' must be zero or negative except at an aerodrome or
within a LFZ. You can probably now see other examples. Pilots should

Where?

Not to get into the whole parsing argument but for the subset of flight
known as VFR, there are no climb and descent rules that apply only to VFR
flight. The rules about airspace and operating limits apply to both VFR and
IFR flights.

That's how I viewed the question. The airspace/limits don't specifically
refer to VFR cruise, although cruising under VFR would still make you
subject to broader airspace and operating limits.

So are there general limits for climb and descent rates that apply to VFR?

I know there are constraints for climbs and descents directed by ATC, but for
climbs and descents initiated by the pilot on his own (which would usually
apply only to VFR, although there are some IFR examples, too), I can't find a
specific maximum or (especially) minimum.
