Big changes to IFR routes in WA
 

Just got the new DAP amendments and next issue charts and noticed that there are some big changes happening all over WA. Biggest changes around Perth, most SIDs and STARs have changed due to all the waypoints moving and also changing names. There is also a large increase in one way routes and many old favorites have completely disappeared.

Should make for some interesting times as crews try to catch up with the new procedures and even more interesting times for those operators that aren't so good at keeping RNAV databases up to date.

I assume this is in response to the reported delays and airspace issues that we keep hearing about.

I guess it’s a bit early but can the crews in WA keep us posted how this one works out and if it helps or makes things worse.

Cheers,
W&F

An AIC regarding this has been on the Airservices website for some time!:ok:

Thats funny..we have huge changes in NZ too. Heaps of new RNAV waypoints and new routes around the middle of the Nth Island.

..actually its probably the king of Taupo again making more room for his skydiving outfit..the new waypoints being called PARRA and CHUTE:O

Cool nothing like changes but it all looks alright to me.

Why?
- Because most of industry refuses to embrace ADS-B, making the huge increase in jet traffic in non-radar WA not economically or safely manageable, resulting in too-long periods stuck at lower levels waiting for clearances;

- the refusal of too many captains to use off-track departures OCTA, thereby forcing nose-to-nose conflicts in the climb or descent, which is at best a silly idea. At least we won't have to worry about the Virgin E Jet aces trying to climb through other aircraft's levels with minimal nose-to-nose separation...

It won't help delays at Perth much. There will still be 40 jets trying to land on the one piece of bitumen that can only handle 24 per hour.

Bloggs,

It might not help with delays (as you so well put it, 40 just doesn't fit into 24!) but it will help us controllers as jets and props will be on different SIDs/STARs so we won't have to push planes around to get everything to work. Provided the weather is nice, it will be a big improvement for us doing the radar enroute around PH - when the weather turns to poo though, it is going to be very ordinary!

On the ADS-B thing, even if every aircraft flying through WA had it, nothing would improve with delays as there is no ADS-B feed into the PH TCU for the flow. All the flow sees are squares (flight plan tracks, ie don't know where they are) or circles (radar tracks). Until they equip PH TCU with the ADS-B feed, there will be no improvement. When will this happen? Got a date yet for hell freezing over?

Also, ADS-B was supposed to have been fully rolled out, completed, operational, yaddah-yaddah-yaddah for 5nm separation by now across the whole continent above F300. Ask any manager in AsA when it will actually get to that point and all you will get is a shrug of the shoulders.

Once ADS-B is all done and the feed is delivered into PH TCU, provided there is decent coverage at turboprop levels out to 250nm+ from PH, there should be a big improvement in the service you receive (won't have to use a procedural standard) and delays will be much better handled as the flow will be able to sequence from an extra 100nm+ out. I wouldn't hold your breath on that happening before 2012 though.....

hey Bloggs

No need to display your jealousy about not flying the ejet!

Its a bit early to tell at the moment but from what I've seen,


Bad

• no more direct tracking (dct HAIGH R21, dct SPUDO R24 etc) when its quiet
• more track miles on SID's and STARS's
• won't be assigned below A100 til inside 36nm
• a certain PJE drop zone more restricted when PH is on R03/06
• changes have to align with AIRAC dates – totally new airspace design goes live for the first time on a Thursday morning :eek:

Good

• No 52 DME hight requirement :ok:
• sperate turbo and jet SID/STAR's so much less likely to be taken off SID/STAR or delayed on climb/descent
• inbound and outbound routes mostly separated, more likely to get unrestricted climb straight to planned level without daft height requirements
• STARS flow from flight planned route – no more recleared to XXX, YYY transition
• all holding points published AND on flight planned track
• many STARS have different tracking for different runways only inside 36nm – RWY changes might actually be safe!
• racetrack pattern into/out of GEL southbound
• NRV inside 125.4 FIA, less broadcasts for PH-NRV traffic
• a certain PJE drop zone less restricted when PH is on R21/24

It would be very interesting to hear what the customers think once its up and running.


NB

Technically, airspace (procedures) can and does create delays. If we are talking about 'capacity', then the runways/taxiways are generally the limiting factor.

Happy to be corrected.

Perth had to go to taxi slot times because TWR could fire aircraft off one RWY fast enough to 'overfil' the airspace. As soon as it calls DEP an aircraft becomes 3nm long and 3nm wide, radar sectors it's 5nm long/5nm wide, in procederual airspace (160nm PH) it's 20nm long and 28nm wide (GPS) or 10 minutres long and 60nm wide. The fact that 90% of PH traffic is in a 135 degree arc doesn't help.

NB

2 days and counting ...

Jepp's seem to have arrived well on time for this update - much appreciated. Now for that RNAV data base .. fingers crossed otherwise I'm off to the lucky shag. :ok:

myshoutcaptain

Have you noticed that the amendment doesn't contain the Flight Planning route requirements? :\ :ugh:

Capt - I haven't no , I am just about to look through .. I did see the route planning as a NOTAM last week however on searching it seems to have gone.

Route data is available from airservices

Scroll down , select , 6 - 6.1 Western Australia

Flight planning post Nov20
 

A word of caution - the new route structure and data are firmly established around 'city pairs' planning. Please ensure you pick the right one or flight plan via the correct TMA/ENR gate so that the magic machine will generate your SID correctly.Also - the new routes do not solve the log jam in the TMA. Turbos and jets will join at about 20nm inbound. Be prepared for some serious speed if the winds are strong up top.Runway changes will be a bun fight - expect to hold if you are outside 50nm when we do the change, until the TMA have sorted out those caught inside 30nm. 03 to 21 will be a right royal pain due to the significantally different number of track miles.Above all - please be patient as we are getting used to new conflict points and airspace configurations. We have done 3 simexs covering varying scenarios and are coping with copious amounts of new/altered local instructions, there will be floor walkers in support for the first couple of weeks so we hope that all goes well.

Floor walkers! Where did you get the extra staff?

Best of luck for the transition - hope it goes smoothly for all.

Cheers,

NFR.

I hope they got rid of that rediculous waypoint called "ALWYN":E

Perhaps they will when you learn how to spell! :}

Who is that joker Alwyn anyway? Who's she upset to get her name in lights? Dick Smith?

Last day for head-on pics tomorrow troops - take your cameras and don't forget to smile as I go past!

Best of Luck
 

Major airspace changes/route structures require an enormous amount of planning, simulation and enthusiasm for change.

Best of luck from BN CTR.....

I know some of my peers in ML CTR especially the BIGHT controllers have a lot of concerns about the changes.

Hope those concerns are wrong??

Good luck to all!
 

Good luck from an ex- West Radar controller now training in Ireland, hopefully all will work out for you guys.

Can't say I miss it though. :ok:

I thought I was already here:E

Although it was called Arrivals when I was doing it in Perth!
