IFR being held at 8,500 feet in VMC – less safety
 
At the present time in Australia pilots on an IFR flight plan cannot enter Class E without a clearance - even in VMC.

In the USA, most pilots on an IFR flight plan take off and climb through E without a clearance to 17,500 feet when VMC exists, which means they are not holding at low levels where traffic density is greater.

Does anyone have a suggestion on how this problem can be solved in Australia?

Capn Bloggs 23rd Oct 2018 02:54

We have 1/20 of the traffic and IFR pilots are legally required to prevent collisions by looking out in VMC. What's the problem?

Dick Smith 23rd Oct 2018 03:09

A big 737 will use more fuel leveling off at 8000’ rather than continuing to climb.

There is also more risk of a collision below 10,000’ compared to above. Why not get above most of the small planes?

Atlas Shrugged 23rd Oct 2018 03:09

Not this again........................FFS!

:ugh::ugh:

Derfred 23rd Oct 2018 03:47

I fly 737’s to Class G airports, and I’ve never had to wait outside class E waiting for a clearance.

Not saying it can’t happen, but if it did it doesn’t burn much more fuel. If I can’t get a clearance it will be because there is another aircraft in my way. In that situation I’d rather stay out of it’s way!

On the other hand, I’m almost always held down at 5000’ for several minutes departing 34R in Sydney in Class C.

junior.VH-LFA 23rd Oct 2018 07:39

When does anyone have a problem getting a clearance though... this is some serious low quality bait.

I'm not sure I understand the question. I am pretty sure in the situation you describe, the pilots will be operating under visual flight rules until they have their IFR clearance i.e. despite the flight plan they are VFR. And the opposite seems pretty common on approach, cancelling IFR once they are visual and no longer need IFR-IFR separation by ATC.

I don't know if there is a procedure to change from VFR to IFR in the air in Australia - it seems like it must be possible?

By 8000 it already has.

Dick Smith 23rd Oct 2018 08:50

Could it be “request clearance”?

TwoFiftyBelowTen 23rd Oct 2018 12:07

You are not correct Dick.
An IFR flight can enter Class E without a clearance in VMC using the “IFR Pick-up” procedure.
(it is not subject to ATC approval....they can’t “refuse” it)

Dick Smith 23rd Oct 2018 13:42

Has anyone actually used this procedure? I have not heard anyone use it.

TheGruntle 23rd Oct 2018 20:40

Why would they need to use IFR pickup Dick when they get a clearance. As seaid previously, on the incredibly rare circumstance that there is a delay in clearance, it is due to there being another IFR aircraft in CTA. And you want to just plough on through?

More often than not ATC will propose another option like a radial or heading to expect clearance on with a very minor delay.

Bear in mind that most aircraft that'll hit 8k fast enough to possibly cause a delay will be covered by company ops that require they don't do IFR pickup and furthermore, I know of places that will require the 'passive' party to IFR pickup to ask for avoidance.

How would you feel if you're IFR, punching along at 9k, or 13k and hear some jet denied a clearance due traffic in CTA only to have that jet then ask to punch through you on their own perogative?

Car RAMROD 23rd Oct 2018 20:51

Maybe no-one has needed to use it because they've all got clearances?

Has anybody here, when IFR, been held below 8500 because of no clearance? Never happened to me, and I've never heard it either on the radio.

Yes. Extensively. It was used as standard practice by a major Adelaide based Flight Training school for years. Departure ex YPPF in VMC but wanting to practice instrument approaches at YPED/YPAD. Depart VFR to SKI then track to HANCH (using point to point nav on the RMI when flying one of the non GNSS aircraft) or Buckland Park and then IFR Pickup.

Dick Smith 24th Oct 2018 01:30

Gruntle, so the advantages of our much proven G airspace and self separation can be used when VMC exists and the advantages of class A when IMC exists.

TheGruntle 24th Oct 2018 01:55

I'm not sure I follow your response Dick. The option of IFR pickup exists. The fact of the matter is that it is rarely needed, in the occasions that there is a conflict preventing a clearance, it is common for ATC to provide another option to ensure segregation such as a radial and in the very rare instances where it is used, the passive party wants out of it. Separation standards exist for a reason. Most everyone buys into them and this issue you appear to be trying to highlight is so rare in occuring that it's a non issue.

Capn Bloggs 24th Oct 2018 02:35

Say what? Pilot to pilots self-segregation comms on the Class E ATC freq? No! :D

As pointed out by Gruntle (welcome on board the Hampster Wheel) you'd be mad and/or an idiot to let another aeroplane, denied a clearance by ATC, go through your level without finding out where they are and what they are doing. Classic Class E hogpodge. Clayton's airspace.

PS: Glad you finally agree our Class G+ is a great system. :ok:

Dick Smith 24th Oct 2018 03:27

Yep bloggsy. Our existing class G is the way to go. An upgrade to E brings in full atc separation for IFR in IMC but professional pilots like you do not need the upgrade. Only an incompetent professional pilot would make an error like the king air one at Mt Hotham. You would never do that so class G can remain. Only those yanks who only designed and built the FA18 would need the upgrade to class E.

Please explain what Mt Hotham has to do with this Dick? That was an aircraft flying an arrival procedure in G, what are you suggesting needs to change to prevent a recurrence of such an incident?

Derfred 24th Oct 2018 08:40

Can I ask you to elaborate on your point, Dick?

Are you suggesting an expansion of Class E airspace, together with changing the rules of Class E airspace to allow uncontrolled IFR in VMC?

In other words, the cloudy bits of the airspace are treated as Class A, and the not-cloudy bits of the airspace are treated as class G?

How does the controller know where the cloudy bits are?


Dick Smith 24th Oct 2018 08:55

In the USA the controllers in E use this system and in many cases the IFR planned aircraft climbs to the highest level available while in VMC.

I am am not sure how the controllers in the USA know what level the cloud starts. Can anyone help with that one?

OK, thanks Dick.

So effectively what we’re talking about is Class G below cloud level and Class A above - varying dynamically with the cloud base.

Sounds fine to me, although with our traffic density is there any need to change the status quo?

As an RPT 737 operator, I currently operate Class G out of places like Kalgoorlie or Port Hedland and hit Class E at FL180. I could be in cloud for all of that time in Class G. If you lowered the Class E altitude boundary, that would take a load off me for pilot-to-pilot separation and transfer that load to ATC. That sounds great to me as an airline pilot, but wouldn’t it increase ATC costs?

What is your motivation for this?

junior.VH-LFA 24th Oct 2018 10:12

I really fail to see (as someone who operates IFR out of Class G daily) how this is necessary or could be justified in Australia with our traffic density.

If there's traffic, talk to them. It's really not that hard.

TwoFiftyBelowTen 24th Oct 2018 13:21

I’ve heard that Class E above F125 where it is currently F180 across the continent is not far away.
Can anybody tuned in confirm???

That is exactly the big sky theory. Talking works most of the time, there have been a few instances where talking failed, and we were reliant 100% on big sky theory. There are almost certainly more we never hear about.

The problem is, accurate navigation i.e. IFR effectively makes the sky a lot smaller. That is why ATC was invented.

Sort of, but only once.

Coming out of Glen Innes in the dead of winter, freezing level well below LSALT with lots of wet, grey cloud about topping at about 9,000. I was IFR, in IMC (but out of the clouds) and ATC said to remain outside controlled airspace.

A quick response of "required due weather" was all it took and the clearance was given.

We have great ATC here in Aus and I really, really had to scratch my head to remember the sole example that might qualify for Ramrod.

This thread should be made into a YouTube video !!

How, just how, did I know that this was going to contain exactly the same drivel as the last 2,000 threads started on the very same subject by the very same person over the past 10 years............. I can hardly wait for the reference to Williamtown Airspace and that bloody VFR lane or whatever it is up there and the Mt Hotham crash........... Oh... I see it's already a few posts back.........oh well, I'll just have to wait for Lismore & Ballina then........

Utter gibberish nonsense

Dick Smith 25th Oct 2018 05:57



Atlas, so sad you are angry with an obvious chip on your shoulder.

You dont have to read or reply to my posts.

Its a a free country and I learn a lot from being involved with this site.

Any success I have achieved is by asking advice and taking notice of the advice which is most likely to be correct.

Thanks to those who post in a positive way!

PS. Mt Hotham, Ballina, Lismore ect!

oggers 25th Oct 2018 12:36

Dick Smith you will of course be able to cite where in the FAA AIM it states that one is allowed to enter class e airspace under IFR without a clearance. Except I don’t know where you got that idea. It is for that reason one gets a clearance void time on every single IFR departure from an uncontrolled airport. You cannot enter controlled airspace IFR without a clearance. You are confused. In the states you can enter class e vfr without a clearance, not IFR. The end.

Oggers,
You do understand the extent of E in US, do you? And the slightly different use of terminology with VFR and VMC in the US? Although the result is the same.
Not to mention the ease of getting a clearance in US, or filing airborne, and I am not referring to radar or VHF coverage.
Tootle pip!!

Often ATC needs to coordinate with an adjacent sector to approve a clearance. As I have been told, “remain outside controlled airspace” is the response required until the clearance is agreed.

Dick Smith 25th Oct 2018 14:29

Oggers Look at my first post again. I made it clear that it was an aircraft that was on an IFR flight plan. I did not say it was in IMC.

My first post is factual. What bit don’t you understand?

Have you ever tried flying a 737 in the USA? It's great not having to worry about bloody CTA steps on descent like I have to here :rolleyes:

Dick,

A thinking pilot will set a standard IFR level OCTA (in your example 8,000 west bound OR 7,000 east bound) until receiving the clearance airborne.
It ain't rocket science.

Atlas Shrugged 25th Oct 2018 22:59


Atlas, so sad you are angry with an obvious chip on your shoulder.
I'm not in the slightest way angry - it's not in my nature, nor do I have a chip on my shoulder........to say that is entirely an assumption on your part

I simply have neither the need, nor indeed desire, to fly in that airspace and frankly, I could not care any less about it. I'm sick and tired of reading the same thing over and over and over again about it.

Having said that

You dont have to read or reply to my posts.
...............as you wish.....

Dick Smith 26th Oct 2018 00:18

To others, I think Atlas Shrugged means he does not want to see G upgraded to E anywhere.

Even though it would maximise the advantages of ADSB.

Incredible!

Dick Smith 26th Oct 2018 00:21

Banjo, that clearly does not solve the problem of pilots having to level off at lower levels when this would not be required in other leading aviation countries. Why not copy the best?
