Checkboard,

Pprune is sure hard work these days. Why on earth would you need a reference ?

What about a LSALT, if that is lower than the MSA?
You're splitting hairs. FAA consider LSALT to be MSA. Local definitions are hardly the point. Call it LSALT/MSA whatever you want the 3 principles equally apply.
What about in a published holding pattern, with a MHA lower than the MSA?
Well that will be another version of a procedure then.
(In Australia) What if you are established on a VASIS associated with an ILS and within 10 miles?
In any country if you're established on a VASIS then you're visual ! The clue is in their title.

The 3 practical rules always apply. Most of us dont need a reference.

Hi, I asked for the reference mostly to determine where you are. The rules change with location - the Australian reference is a case in point, as you can't descend below the MSA at night, even if "visual" unless you are within 3 nm or on a VASIS, or conducting an instrument approach.

New question considering full procedure approaches

EHAM ILS approach 06

http://www.ais-netherlands.nl/aim/20...-IAC-06-1.pdf?

So imagine approaching RIVER and having a comm failure (just to avoid responses like you will normally receive vectors and ATC will tell you what to do etc.)
I know entry in procedure turns is restricted to 30 degrees left and right but the angle overhead SPL VOR is to sharp to make a normal turn.
So you enter the hold for repositioning to be able to continue to the NDB (correct?)
Is there a maximum angle here that allows you to take the turn or reposition in the hold? (like the 30 degrees with a procedure turn) I found something about maximum 90 degrees in a precision approach and 120 in a non precision but I believe this is the maximum angle between the initial approach and the intermediate approach.

Can someone clear this up for me?

Thanks!
