Five Amended TAFs in less than 90 minutes, that has to be a personal best. Listing the METARs and the ATIS for the same period would be very interesting.

Perth Fog,



With $35 million spent, to upgrade Perth to Cat3 b landing in 2018, why are so many in the industry not yet certified?


Basic Questions regarding DH concept for CAT I/II/III Ops

Money. An accountant has done the sums and has figured out that the cost of the average number of diversions due low fog and re-accommodating pax is still cheaper than training crews and maintaining equipment to low vis standards.

It is a step by step assessment, always complying with the rules until you have the circumstances such that you can no longer comply with all of the rules.
eg. You carry 10’ hold for ATC and they tell you that it will be 16’ and you don’t have it.
You’re not just “entitled” to continue an approach. If you’ve truly passed a “point of NO return” then literally you have no other option than to land on the bitumen at that airport which may have suddenly gone down to 300 metres vis in unforecast fog, using the capabilities of your aircraft to their maximum possible potential to ensure the approach is as accurate as it can be. The only other alternative (wouldn’t really call it an alternative) is a Norfolk Island ditching situation.

Cat lllb is as much about airborne equipment as it is crew training. Which aircraft have fail safe multi channel approach capability that aren’t currently using it? Even the standard 737 with its basic 2 axis autopilot* isn’t Cat lll certified. Its only by using the HGS that QF can do it at all.

* Apparently a 3 axis option exists, maybe Virgin has it?

Or try Pearce.

If budget carriers in Asia can train their crews, maintain currency and keep the aircraft up to scratch, it bewilders me why airlines in Australia can’t do it. For gods sake it was an extra 30mins or so in the sim session every 6 months to maintain currency and that was it.

FFS, in an airline, a pilot just can’t go to any piece of bitumen that suits them.
An Alternate has a capital for a reason. It is assessed for all sorts of criteria and if it meets the tests it is approved as an Alternate.
Then there are others. Airports for use for twin engine aircraft for use when they have problems. They need to be approved. Then there are Emergency Airports which are assessed and approved for use in emergency, but emergency is not really a real emergency. Then there are funk holes. They are bits of bitumen where the PIC reckons he/she can put an aircraft down.
Most , but not all military airports in Australia don’t get assessed as an Alternate. There are a couple of exceptions.

Hey Austral………

We don’t have any HGS at VA but we have 3B approval in the old girls. Not all machines, just the fail operational SFP’s. The earlier models are only fail passive so Cat 2 only. The fail ops do compensate for rudder so 3 axis I suppose, whereas the fail passives don’t.

In the Perth scenario, presumably you would find any piece of bitumen that suits rather than attempting a ditching. While Perth may have fog, Pearce may not.

Emergency Fuel is very important and the delay in planning is unacceptable.

It's about time we saw some strategic thinking and planning, because if we keep cutting it that tight we mightn't be so lucky next time

10 years ago, we are still waiting

https://www.watoday.com.au/national/...124-1qew3.html

Controllers and crews at times resorted to discussing the alternative landing strips at the RAAF's Pearce base in Bullsbrook north of Perth, when winds reached 40 knots at the runway's threshold, as well as its Gingin airfield.

One crew even asked about Rottnest Island which also has an east-west runway but no night landing facilities, according to the aviation website.

And everything from the -300 onwards is CatIIIa capable.

Cat2 or Cat3a? If only Cat2, thai's interesting- is it an Aussie thing that you can't do Cat3a fail passive?

At QF anything below Cat ll has to manually flown using the HGS. Since you have to disconnect the 2 axis autopilot right after touchdown to prevent unwanted roll input in lieu of yaw I think they settled on Cat ll being the limit for autoland. That also may have been informed by too many dodgy roll outs in other than low visibility conditions when the ILS wasn’t protected. A Boeing tech bulletin refers.

QF has of course only one HGS, and the F/O is subjected to 90 seconds of terror watching me be a meat servo while staring into the sole low viz guidance source.

It may not have that fog but as it’s only a few miles from Perth and at the bottom of the scarp as well very good chance Pearce is affected by the same fog as Perth. Way too close to be considered a practical alternate.

Best bet is for all jet operators be capable of conducting low vis approaches. This isn’t a new concept, Tridents were doing low visibility approaches in the early 60s.

Can the VIP RAAF B737 BBJ aircraft land in CAT 3 b at Perth?
I imagine it can.

I should have explained a bit better. The later model SFP’s are certified to 3B fail op. Due to snags they can be downgraded to 3A fail passive such as LAND 2, like if the IFSD shits itself, etc. The earlier models that we have are (no IFSD) only certified to Cat 2 fail passive so any problems and it’s straight back to Cat 1. Neither have HGS.
