Missed Approach - when to climb?
Here's an interesting one I can't seem to find an answer for in the AIP.
ENR 1.10.1
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 tolerance for the aid in use; or
b. during an instrument approach and below MSA (as specified on the IAL chart) the performance of the radio aid becomes suspect, or the radio aid fails;
Most plates say "track xxx, at xxxx feet turn left/right" etc. Diagramatically, they show the climb beginning at the MAPt.
In both the above cases, there's a good chance you won't haven't reached the MAPt or DA/MDA. So do you level out and track to the MAPt before starting to climb in the hope of getting visual, or do you start your climb straight away knowing that if your aid has failed and/or you are off track, you may be heading for a nearby obstacle (because you are no longer on the IAP flight path)?
I have seen both suggestions in other literature, but can't find a definitive answer in the regs. Maybe I'm not looking in the right place . . .
