I can think of the following situations where I might encounter a full
deflection yet a recovery is the right thing to do:
1. Flying an ILS behind a heavy to a 9000 foot runway with an 800 reported
ceiling. I want to land long, stay well above GS and might accept a full
deflection high.

2. I have a full lateral deflection, but I just WATCHED it deflect full and
I therefore know where I am, my distance from where I want to be, and I know
that I can recover. (as opposed to I was distracted, lost my scan, look up
and see a full deflection but I have NO idea how long it has been deflected
full)

3. On a VOR approach, I just passed the VOR as FAF and the CDI swings to a
full deflection. I know I am on course because I was only one dot off a half
mile before the vor and I will likely be the same one dot off shortly.

Think about it it just makes sense. Once you have full deflection you can
no longer tell where you are latterly on the approach. An unsafe
situation.

It is common wisdom, and often common sense, that if a full deflection of
a CDI (or GS) is experienced, a missed approach is to be flown. But a lot
of people seem to think that it is REQUIRED. I have had a CFII tell me it
is required. But I can not find anything in FAR or AIM that states such a
requirement.

Again, in a lot of cases I can understand why to do it. But I can also
imagine others where it might make just as much sense to recover the
approach and not go missed.

Can anyone point me at a rule that requires a missed?
