There are no climb gradients on FAA missed approaches for public
procedures except for Burbank, California. They are evaluated for a 40:1
clear surface from (typcially) 250 feet below MDA to not less than 1,000
feet below the final missed approach altitude. Hopefully, you can climb a
lot better than 40:1 (152 feet per n.m.)

If no fix is specified you turn when you reach any specified intermediate
turning altitude. It's protected for the worst climber (152 feet per
mile) to an F-18. If there is a turn fix specified, you keep climbing
(assuming you're out climbing a 40:1 slope) but you don't turn until the
specified fix.

With the KCNO ILS you turn as soon as you get to 1,400 feet assuming you
are past the MAP. If you miss early you don't turn until the MAP but you
can keep climbing towards 4,000 feet. The missed approach hold is shown
in the plan view as right turns on the PDZ 078 radial. If you're a slow
climber and you reach PDZ below 4,000 feet you continue the climb in the
hold to 4,000.

At KCRQ you climb on heading 245 until you intercept the Oceanside 145
radial (325 inbound). Whether you reach 3,000 before or after
intercepting the 145 radial is irrelevant, you intercept the radial at
3,000 level, or climbing to 3,000.

Perhaps an example from "nospam" of an actual plate would be more
instructive.

Take a look at the ILS to RWY 24 and (K)CRQ

This is where I saw the missed. It is not a good example as the missed
takes you out over the ocean and in fact either way you look at it, it
would be safe.

I'm just trying to understand in the general sense what the rules are.
In reading the recent AOPA magazine it had a sumary of accidents in
CA and one was someone getting a radar vector and assuming that he
could let down to the crossing altitude of the next segment.
He did this at night and it was fatal.

I understand that not understanding the subleties of what the rules
are for flying IFR can also be Fatal so I'm just trying to understand.

Another approach with a similar missed that is unlclear:

KCNO ILS RWY 26R

Missed:
Climb to 1400 then climbing left turn to 4000 direct PDZ and hold.

Looking at the plate missed seems to be about 4 mi from PDZ.
DH is 836 so at 200ft /mi 1400 gets you to 6 mi from PDZ
Assume that the turn gives you another 200 ft thats 1600 and 6 miles
at 200 per nm that gets you to PDZ and 2800.

The missed specifies 4000

So what do you do hold at PDZ and climb to 4000?

Again in this specific case it looks like that would be safe.
