NZ RNAV procedure turns
On the Wanganui RNAV approach plate for runway 11, I notice that if you come in from the IAFs from the SW or NE (i.e. not DUDED), there isn't a noPT (see here: www.aip.net.nz/pdf/NZWU_45.1_45.2.pdf ).
I normally would see this on FAA charts (see here for example: flightaware.com/resources/airport/KBGR/IAP/RNAV+(GPS)+RWY+33 ). I'm assuming you wouldn't be expected to do the procedure turn when starting at BUPKA or AVLOR? Any idea why the CAA doesn't indicate you don't need to do the PT? |
Not quite sure what you're asking, but in Australia the charts look pretty much the same. You can: #1 honour the RNAV capture region, or #2 make whatever sector entry is appropriate (using the sector LSA) an any entry point.
I certainly do not make a hold without a good reason (delay). If you're a student/low-time IFR pilot, you might be thinking that holds are normal. Not the case, they're very abnormal - it's a long time between holds - only made if required because you need the time or to delay ... why burn expensive holes through the air when you could go straight there. If you do make a hold without telling Centre, you'll get all sorts of confused questions :) They expect training aircraft to do that stuff as part of "airwork" but not real IFR flights. |
I'm not sure what you're asking either. You don't need to do any procedure turn, you just fly to the most appropriate iaf and do the approach

He's asking why the term 'noPT' is not displayed in on the legs between the initial and intermediate fixes.
Firstly, CAA don't publish the NZAIP, but that's semantics. The reason you don't see 'noPT' - you won't find 'noPT' on any New Zealand chart - I don't think it's actually a PANS OPS term. It shouldn't matter anyway, because from a practical standpoint, you couldn't make a procedure turn even if you wanted to - they are used for reversing direction (when you're talking straight-in approaches like this), and there is no way you can fly this approach that would require a reversal. |
Thanks, Rudder Sir. That's what I was looking for. Agree with the others that it'd be impossible to make that course reversal otherwise. The noPT must be an FAA special from low-time instrument pilots who've tried to crank in unneeded turns.
To your point that they're for reversing course though, if you come straight in, you'd also be expected to make the procedure turn? I understood they can also be to lose altitude. |

‘No PT’ means exactly what it says - a procedure turn is not permitted. If it’s not there, then a PT is permitted. If the PT is depicted, then it’s required unless you’re on radar vectors.

Ironic, considering your question. It means that you’re not protected if you attempt one.

No, even if it's there you don't have to do it. Don't confuse USA rules and procedures to NZ, they are not the same country.
The T layout / multiple IAFs are there so you can come from any direction and fly straight in. That's the beauty of RNAV in that it's point to point. Not referenced to only one point. The only time I can think of having to do a procedure turn on an RNAV is if there is only one central IAF and you are not coming straight in. I know there used to be a few RNAV approaches in NZ like this as I had to do them, but this was a long time ago in the more infant stages of RNAV approaches in nz. I doubt there are any (or many) around like that still.

The fact that a procedure turn is still applicable if your IAF is the middle waypoint (but you aren't under radar control, say) gives an indication there is an additional purpose.

Thanks for the clarification and the rest of the detail. Being a completely optional turn is very different to the US.
States (nations) choose a design standard. The two most common are ICAO PANS - Ops and TERPS. |
