C'mon Rob. It's Qantas. It'll be somewhere between 0 and 3% with the flat 3 looking the likely option.

Going Nowhere 1st January 2014 23:31

You'll be doing well to even get 3 out of them at the moment! :(

Does Eastern or Sunstate have "operated by" on the side of their aircraft?

Capt Claret 2nd January 2014 03:38


There is no way Ansett flew DC9s from CBR to BNE. It didn't have the range nor performance.
TAA must've had better DC9s than Ansett then because I flew in one SYD to Townsville in 1980, and they often ran MEL-BNE-MEL, both longer stage lengths than CBR-BNE. :ugh:

Capn Bloggs 2nd January 2014 04:03


MEL-BNE-MEL, both longer stage lengths than CBR-BNE.
C'Mon Clarrie, sealevel ports with runways longer than 50 MCGs can't be compared to CBR 35 at 35°.

nitpicker330 2nd January 2014 04:07

I never flew the 9 but I do know that CBR was a problem especially at hot temps. Elev terrain temps etc etc.

Capt Claret 2nd January 2014 04:12

True Bloggs but the 71 isn't the only aircraft that can be payload limited ex CBR, 727, DC9 from the distant past, 737 300/400 from more recent past. If the decision is made to upgrade to C engines I'd guess the problem will possibly be no more.

PPRuNeUser326772 2nd January 2014 05:20

" jet like speeds", sorry couldn't let that one through to the keeper.
Wondering which jet is as slow as 360kts, the max cruise speed of the Q400?
Even the 146 would happily cruise at 400, most other jets are at least 100kts quicker than the Q400

Confucius say "props belong on boats"

Fuel-Off 2nd January 2014 06:38

And jets belong in spas... :E

Fuel-Off :ok:

KABOY 2nd January 2014 06:52

Bring back the 146, i don't recall it having severe payload restrictions ex-CBR in the summer!

For all its faults it could still uplift a decent payload off short strips.

Icarus2001 2nd January 2014 07:05


I don't care if Cobham flies 717 s for Qlink but FFS put Cobham on the side of the aeroplane and tell the public.
It is on the side of the aeroplane by 1L. It is also on the boarding pass.

How does a thread about weight limits on a type end up about pilot salaries. (Rhetorical question) :ugh:

Just think of all the code-share aircraft out there that will now need multiple titles on the fuselage.

The reality is that QantasLink is a single brand set up by Qantas. It's aircraft are owned by multiple entities and operated by multiple entities, some Qantas owned and at least one, not.

Farm gate 2nd January 2014 08:12

From memory the SIDs in Canberra only included terrain clearance in the late eighties, by which time the DC9s had retired. On hot days the Nine mostly departed on 17 with a lot of tailwind.

When the new SIDs included terrain clearance requirements the payload on departure for all aircraft dropped significantly.

I would expect that that is why the Nine operated with a higher payload than the 717?

neville_nobody 2nd January 2014 08:17

If this problem is actually true doesn't QF run afoul of IATA rules in regard to a non stop flight. You cannot advertise and charge people for a non stop RPT flight if you have to keep making tech stops enroute because it is no longer 'non stop'.

Martin VanNostrum 2nd January 2014 09:13

Ansett DC9's
 
I flew the 9 for Ansett in the early '80's till they were retired in '82. I cannot ever remember operating CBR-BNE in it. From memory all BNE flights ex CBR were via SYD. We operated plenty of CBR-MEL and CBR-SYD though. You have to remember back then (30 years ago) BNE was a backwater and the airport was Eagle Farm which was small and basic. There was nothing like the traffic today. I just don't think there was the demand for CBR to BNE direct; however I may be wrong.

Jack Ranga 2nd January 2014 09:17

It's still a backwater from what I hear ;)

Capt Claret 2nd January 2014 09:51

All this palaver is probably moot in the long run. I suspect a statistical analysis at the end of 12 months will probably find a relatively small percentage of flights couldn't carry the load on the day, and an even smaller percentage made tech stops. And then when the engines are made into Cs, the refrain will be "problem, what problem".

Flava Saver 2nd January 2014 12:28

...also remember being in a TAA DC-9 TSV-SYD which also had a massive thunderstorm on arrival back in the early 80's, and we held for yonks...

SIDS N STARS 2nd January 2014 12:48

I pax'd on one of these birds last week. From where i was sitting, looked like every second seat pocket was missing/torn/half attached, unable to hold anything!! Due to short flight time, unable to use IFE.

Not just performance problems??

I dunno what the J class passengers get..

critical temps for CBR
 
Hey Clarrie,

What are the critical OATs for departure 35 for the A and C engines?

A rough look at the BoM max temps for the last 5 years for CBR airport for January shows a monthly mean of 30.3C with a standard deviation of 4.7C, based on 153 daily observations showing a range of max OAT of 23.4C, the highest being 42.0C. The distribution is a reasonably symmetrical approximation of the normal distribution, so even Alan's mathematical genii in Route Planning can easily calculate the probability of a particular temperature occurring during that month. For a slightly bigger bonus, they could probably develop a correlation estimate between the new airport data and the old airport data (kept from 1939 to 2010) and work it out on a daily basis to match the traffic data.

For a huge bonus, they could even talk to Yield about providing a daily seat limit, making it easier for the boys to manage the variations on the day.

Now, getting back to the troll's original bait, the cost of power by the hour for a 21K engine compared to an 18.5K engine is eye-wateringly disproportionate for the number of take-offs required above 18.5K. Let's just say you need 21K for 30 departures but the rest (say 120) are at maximum derate of around 15-16K: you pay for every minute of time in service as if you are spinning the fan off the front at max TGT through the emergency gate.

Would I assess the probabilities of getting away with 18.5K engines :E or would I just pay through the nose for 21K and look at it after 3 months? :eek:

Farm Gate,

Anybody limiting TOW to maintain OEI SID compliance at CBR either had big expensive engines or doesn't grasp the benefits of Special Departure Procedures... :{

Neville N,

I didn't realise that IATA had taken over from the ACCC in protecting consumers... :uhoh:

Stay Alive,

Blitzkrieger 2nd January 2014 20:50

SIDS N STARS, welcome to the wind up :)

Sorry to hear our newly re-fitted interior has been destroyed already.

Regarding the IFE, I am assuming you were travelling between SYD-CBR. How would mainline or the real q-link handle the IFE on a 25 minute sector?

Some one also mentioned the temperatures QF used to predict the performance of the 717. I am told the figures used were yearly mean temperatures (mean max in the hottest month of January 28.5 deg). Which would indicate to the QF performance guys that there would be no restrictions even with 18.5k engines. Obviously an overly simplistic approach you could say.

Prince Niccolo M 3rd January 2014 02:05

which would indicate that it was a heads or tails bet that the OAT would be higher than 28.5 deg... :(

UnderneathTheRadar 3rd January 2014 02:17

Almost but not quite.......

How's it Hanging 3rd January 2014 02:40

Most aircraft with weight issues off rwy35 in Canberra can go with 10kt tailwind off rwy17 at much higher weights.
Does that work for the 717?

Blitzkrieger 3rd January 2014 09:43

Yes it does.

Typhoon650 3rd January 2014 20:04

Any IFE on a 717 has got to be better than on Qantas's ancient 737's. Nothing like 3 or 4 tiny old CRT tubes (with obligatory safety tape on the bottom for anyone over 165cm tall) and a VCR for the latest and greatest.
How Qantas get away with charging at all for flying in a -200, I don't understand. It's like sitting in a doctor's surgery in 1980....

Capt_SNAFU 3rd January 2014 20:25

-200's your on drugs. Haven't even had 300's for years. The IFE in the 400's is crap but what do you expect when they will be gone soon.

As for performance issues not alone in that department. QF 737s had issues with de rated 800s going into places.:ugh:


Which would indicate to the QF performance guys that there would be no restrictions even with 18.5k engines.
Why is QF performance doing things for Cobham?

josephfeatherweight 3rd January 2014 20:28

Does not utilising the offset Type-A chart for RWY 35 (353 degrees) provide an OCTG of around 3.4%? Please note, I'm not privy to the Cobham SOPs, but can they not employ such methods to calculate departure, or is the 717 performance worse than that... From memory (and it's scratchy), the use of the offset Type-A chart permitted departures on RWY 35 ahead of RWY 17 due to the reduced gradient and the lower MSA to the north (4600' vs 5100'/7500' to the south).
Interested to know if I'm a) wrong or b)how they are specifically restricted by a 35 departure.
Thanks.

It won't matter soon... Once Network get their 20 red tail A320's I don't think the 717 or cobham will be needed much longer (Qf shorthaul either for that matter). Checkmate.

Capn Bloggs 3rd January 2014 22:31

Snafu, who said QF Perf was doing anything for Cobham? QF would have done internal assessments regarding performance; these routes, after all, are QF routes.

No. Have a look at the current Radar and RNAV SID and tell us what the gradient is. ;)

Haha, probably right! They are in the business of going broke ;)

Nah, I'm aware of the 6.6% gradient required for RWY 35 SIDs, but for my operations, that's not a show stopper when you can calculate other options.
Options (in order of ease/preference):
1) If you can achieve 6.6% to 3400' - great, easy.
2) Can't make 6.6% - what's the standard (straight ahead - as published in the RDS in ERSA) splay gradient? Can I achieve that? Can I also achieve the 25nm MSA by the end of the splay?
3) Can I use the 5 degree offset splay gradient (I think about 3.4% from YSCB RWY 35 Type A-Chart). Can I achieve that? Can I also achieve the 25nm MSA by the end of that splay?

Surely Cobham/Qantas/Virgin don't always have to achieve the 6.6% gradient requirement?

How'd you work out 3.4% when the published departures on the 353 (5° rght offset) give a gradient of 6.6%? What splay dimensions are you using?

mustangranch 4th January 2014 02:05

Am I missing something? Generally it is hot weather that causes this issue. Therefore it is probably cavok. What would stop a visual departure being requested? Just a thought, I am no doubt wrong.

As mentioned previously, using the YSCB Type-A Charts. Sorry, I'll amend my post to make it clear...

Capn Bloggs 4th January 2014 02:22

My understanding is Hi cap RPT operators do not allow Visual Departures.


using the YSCB Type-A Charts
I'm not familiar with Type A charts. What splay left and right of the departure track centreline (in this case 353° from the DER/VOR/ECKKS) do they assume when coming up the 3.4% value?

BPA 4th January 2014 02:29

HC RPT DEP at Willy are given a visual dep unless the weather requires a SID or Radar DEP.

Capn Bloggs 4th January 2014 02:53

That may be so, but do the crews then use visual tracking performance charts as opposed to IMC tracking performance charts?

josephfeatherweight 4th January 2014 03:19

Ok - a few things to clear up.

The gradient is important to consider in the one-engine inoperative case - it doesn't matter if you're IMC or visual - the only difference is, if you're visual and you're not achieving the minimum gradient to avoid the ground, you'll get a great view of the it before you smack into it...

Type A charts are usually provided by the airport authority and cost a fair bit to a) produce and b) purchase. They identify ALL obstacles in the splay (based off the centreline, usually, but sometimes in special cases they do offset calcs such as at YSCB RWY 35) which is a straight line extending out to 15,000m with a 15 degree "splay" either side. The benefit of a Type A chart over the basic RDS info is that you can identify the most limiting obstacle and hence the most limiting gradient. Pretty sure the splay is based off 35' from the DER - haven't looked for a while and don't have my docs with me...

Anyway, with the above data, you can calculate less restrictive engine out climb gradient requirements...
