AIP ..ILS - Also confused
AIP 1.5- 32 7.3
Altimeter Checks:
The final aproach contains a fix (FAP) at which the glide path/altimeter realationship should be verified. If the check indicates an unexplained discrepancy, the ILS approach should be discontinued. The following should also be complied with:
a. To maintain obstacle clearance,both LLZ and GS should be maintained within half scale deflection (or equiv. on expanded scale
b. If at any time during the approach, after the FAP, the LLZ or glideslope indicates full scale deflection, a missed approach should be commenced.
c. For ops where the temperature on the ground is colder than -15c the DA/H should be adjusted for true altitude.

A missed approach must be executed if:....
A: during the final segment of an instrument approach, the aircraft is not maintained within the applicable navigation tolerence for the aid in use
(b) seems to contradict (A)
What the...?
