No Radio Dick: The Next Instalment

[Capn Bloggs]

"Well,
On with the show. A couple of near-hits ain't gunna stop me!"
The CASA NPRM for changes to operations at non-controlled aerodromes has been posted here.

Safeskies, I note you made it into Flight International: well done. We need a similar petition for this MBZ nonsense!

[89 steps to heaven]

I might be having a bit of a slow start to the week, but after briefly reading the NPRM, I am not sure how or if part time CTAF's will work.

At an aerodrome where there is a part -time tower, non 24 hour op, outside of tower hours, does the CTAF become a non towered aerodrome and aircraft without radios are then permitted, or does it still remain by definition a towered areodrome.

If it is the 1st case, then I can see it raises problems with resuming tower operations as there may be aircraft in the airspace, not in comms. Also, there has to be an additional risk should the tower have to either open early or close later than published hours (normally to accomodate an RPT or an emergency).

As this change is not to comply with an ICAO procedure, I am also interested in what safety case the NASIG has, or will produce.

Incidents before 27 November 2003 - no emotive media releases, no Category 3s (Part 1

Captain Bloggs, you state

“Well, on with the show. A couple of near-hits ain’t gunna stop me!”

You imply that I do not have a concern for aviation safety. I can assure you that the opposite is the truth.

Following is a list of just some of the serious unalerted see and avoid and RA incidents which took place before 27 November 2003. Please note that all of these have simply been filed in respective databases and no proper "system safety" action has been taken.

The plan of the NAS is to reduce the number of these serious incidents. You will no doubt note that most of these serious incidents take place close to the aerodrome area where the risk of collision is highest. The new airspace system, following international practice, will concentrate resources close to the aerodrome to reduce this type of serious incident.

Captain Bloggs, can you advise why you have never campaigned against the very high number of incidents (as shown on the list) that take place close to the aerodrome area in the airspace before 27 November 2003?

I look forward to your advice.

Incidents before 27 November 2003 – no emotive media releases, no Category 3s

1. BOEING 747 POTENTIAL MID-AIR COLLISION – 400 LIVES!
Brisbane. Occurrence number 9601917. Incident category 4.
An air traffic controller made an error where an air transport Boeing 747 could have collided into the rear of an air transport BAe146 jet. The report states, “Had the aircraft not been fitted with ACAS, or had the crew not queried the controller, there was the possibility of a collision. Without an ACAS the crew may have observed the BAe146 through the aircraft’s windscreen, however this would have been subject to the crew’s cockpit workload.”

2. NEAR MISS, UNALERTED SEE AND AVOID, “FILLED THE SCREEN”
Taree. Occurrence number 9701187. Incident category 4.
A Piper Chieftain was enroute from Williamtown to Kempsey at 9,000 ft, and an air transport Dash 8 was flying from Taree to Sydney. The Chieftain had the Dash 8 fly across and directly in front of them. The crew of the Chieftain said the aircraft “filled the screen”. The Dash 8 crew knew nothing of the incident until they landed. Neither aircraft was given traffic on the other.

14. AIRLINE DASH 8 “EVASIVE MANOEUVRE” SAVES MID-AIR COLLISION
12 April 2001 – Dubbo
Occurrence number 200101714. Incident category 5.
The crew of an air transport Dash 8 reported that when they taxied for departure, and in reply to their transmission, the crew of a Cessna 152 responded that they were operating in the circuit area. The airline crew requested that the Cessna crew advise when turning onto final, then lined up the Dash 8 on runway 23. The airline crew had not heard a call from the Cessna and commenced their take off run. As they were committed to take off and about to become airborne, the Cessna 152 was sighted ahead and above at low altitude. An evasive manoeuvre was carried out by the Dash 8 crew.

15. AIRLINE DASH 8 UNALAERTED SEE AND AVOID – NEAR MISS
24 April 2001 – Dubbo
Occurrence number 200101900. Incident category 5.
The crew of an air transport Dash 8 reported that while they were on descent for landing, the aircraft’s TCAS activated an RA on opposite direction VFR traffic climbing towards them. All the appropriate radio broadcasts had been made with no response from the other aircraft. They responded to the TCAS advice by climbing their aircraft which caused tem to re-enter IMC. When the other aircraft had passed they descended again for an uneventful landing.

Dick

Don't bother posting reams of incidents just to prove you care.

It would be more constructive if you could give some guidance on my question please.

[Next Generation]

Dick Smith

It all started to go bad way back when someone decided to introduce the concept of "Affordable Safety"

Dick, you are determined to see your pet project through, and just like an over-protective parent, whose child can do no wrong, you fail to see the shortcomings of the NAS and continue to ignore the majority of the aviation community concerns.

Press on, ignore those of us in the industry at your own peril.

You only see things from a Private Pilot perspective, but I am sure that the Australian public are more concerned about the effects on Airlines.

In response to your big list of close calls prior to 27 November, you have failed to explain how the skies are NOW safer.

I can't see the improvement.

Please enlighten us all.

78. 22 November 2003 – Tamworth
Occurrence number 200205830. Incident category 5.
While inbound and assigned 5,000 ft visual, the pilot of a Piper Cherokee aircraft descended to 4,300 ft without approval, resulting in a breakdown of separation with a Dassault Falcon 200 outbound on a practice NDB approach at 4,000 ft.

79. 15 May 2003 – Coffs Harbour (Note: ATSB says not a serious incident – no press release!)
Occurrence number 200302172. Incident category 4.
During a GOS approach to runway 21 in reduced visibility, a Beech King Air aircraft’s left main wheel stuck a breakwater in the harbour north of the aerodrome. The wheels on the left main gear detached from the aircraft. The pilot initiated a go around and operated visually east of the coastline to enable rescue and emergency services to position on the aerodrome. The aircraft landed safely a short time after.

[Shitsu-Tonka]

Dick Smith:

I am a little confused at the exact point you are trying to make with your post.

Is it a case of "here I can prove we have lots of near-misses and TCAS saving the day before so on that basis we can now officially rely on unalerted see and avoid?". Is that really a case for removing the radio?

There is no mention of course of how many times pilots (on the right frequency) actually sorted out a satisfactory separation arrangement - or just simply were aware of other traffic in the circuit. Is that because it happens every day?

'unemotive examples'?? (who wrote the bylines like BOEING 747 POTENTIAL MID-AIR COLLISION – 400 LIVES! , NEAR MISS, UNALERTED SEE AND AVOID, “FILLED THE SCREEN” - the ATSB?!)

You say the NAS follows international practice - is this moving away from a strictly US system - the one that John Anderson says we will now have?

wtf? NAS? I think you have truely lost it now dicky boy.

[Howard Hughes]

Dick, Dick, Dick, (shakes head)

Having briefly read the incidents that you have so painstakingly put up in defence of NAS I would like to say this.

From my observations the majority of these incidents seem to take place OCTA, or there is a blatant cockpit breakdown (ie: non adherence to an ATC clearance!!).

The incidents post NAS have occured with high capacity RPT jets on descent into controlled aerodromes, where everybody involved was conforming to their clearances or proceeding as class E airspace allows.

Now my question is this, can you not see the difference between the pre and post NAS scenarios?

Secondly how can removing frequencies from charts whilst still expecting people to be on an "appropriate frequency" enhance safety OCTA? You yourself have already quoted a myriad of incidents pre NAS, that have in the large part been caused by miscommunications and/or aircraft with incorrect frequncies selected.


Cheers, HH.

PS: safe flying all.

Your entire post is disjointed and makes no sense at all.

You have not answered any of our questions.

79. 15 May 2003 – Coffs Harbour (Note: ATSB says not a serious incident – no press release!)
.....The wheels on the left main gear detached from the aircraft. The pilot initiated a go around and operated visually east of the coastline to enable rescue and emergency services to position on the aerodrome......

What the HELL has this got to do with NAS ???

Or did you just go off half-cocked without reading what you were actually cutting & pasting.

As this is a serious issue, (at least it is amongst professional pilot's), please have the courtesy to read whatever it is you are copying.

[Dick Smith]

Next Generation, I did not introduce the concept of affordable safety. I've never heard of anything so ridiculous in all my life. Safety has always been limited to what society can afford. That's why you have to be very astute and allocate the finite resources so they save the most lives.

The additional safety from 27 November changes comes from the fact that air traffic controllers and pilots will be more able to concentrate their resources where the collision risk is higher - that is closer to the airport. This will be reflected in a reduction in the number of serious safety incidents. The reason Class C airspace above places like Launceston has been changed to Class E is so that air traffic control resources can be moved to where the collision risk is highest and where the most serious incidents have been occurring.

Next Generation, you state:

I can't see the improvement

Of course, if you just look at incidents which take place in Class E airspace and not also look at incidents which take place in airspace closer to the aerodrome you will not be able to see a change, however, if you objectively look at the situation you will find that by concentrating air traffic control resources to where the collision risk is highest, that safety will improve.

To save answering a further question, the reason that unalerted see and avoid incidents will be reduced in MBZ airports is because VFR aircraft flying enroute will no longer be monitoring hundreds of calls which are irrelevant. The new system is simpler and will result in higher compliance rates in the airport area and there will be less "defusion of responsibility" because most calls received by a pilot in Class G airspace will be relevant traffic information. The USA appears to have a lower number of unalerted see and avoid incidents reported in the circuit area of aerodromes. This is primarily because there is no enroute ATC frequency for VFR pilots to monitor, and there is a simple and straight forward CTAF system that is common at every non-tower airport.

The reason the Coffs Harbour incident is mentioned is due to the fact that the ATSB did not send out a press release about it, whereas they did in relation to the Launceston incident.

[89 steps to heaven]

Dick

Still no answers.

Can't or wont?

Again

[DirectAnywhere]

Dick, I'll post additonal comments relating to 2c on here when I have more time. I've just downloaded the NPRM and am frankly quite disturbed by what I've seen on a brief read through.

I've just got a couple of quick questions at this stage.

That's why you have to be very astute and allocate the finite resources so they save the most lives.

At this stage, what cost saving is there to the tax payer in amending MBZ/CTAF procedures to this extent? Surely it doesn't cost the taxpayer a cent to leave these procedures as they are. No resources will be saved, in fact taxpayer dollars will be wasted as a result of these unnecessary changes. Scarce dollars that could be better spent, perhaps, in educating pilots better on our current procedures?

the reason that unalerted see and avoid incidents will be reduced in MBZ airports is because VFR aircraft flying enroute will no longer be monitoring hundreds of calls which are irrelevant

Any aircraft flying in an MBZ should only be hearing the calls that are made from within that MBZ and as such are directly relevant to the operation. This point simply doesn't hold water!!

where the collision risk is higher - that is closer to the airport

You accept this fact - in essence it is the raison d'etre for ALL NAS amendments. However, 2c seems to directly contradict this through the removal of MBZs. If this NPRM is accepted you will have High Capacity RPT aircraft that will be sharing airspace with aircraft that may or may not have radios. This can only lead to an increase in

serious unalerted see and avoid incidents.

The new recommended procedures, and a requirement for pilots to

take all reasonable steps to ensure that his/her aircraft does not cause a danger to other aircraft

are too general and, at the end of the day, are only recommended procedures.

I can assure you that I'll be responding to this NPRM through the appropriate channels also and resisting these changes.

As I said, I'll add some further comments later but I would urge you to reconsider this.

[Shitsu-Tonka]

OK! Now I get it.

The whole point of your post is that you have an axe to grind with the ATSB.

You obviously are not happy with the fact that LT was delcared an airprox? How close do you want them to get before it qualifies? If it makes you happier I would say that a fair swag of the examples you quoted OCTA prob qualify for airprox too.

This is really a case of playing the man not the ball - the problem isn't that ATSB or whoever don't like you Dick - it's that they don't like your system. Along with the majority of airspace users, air traffic controllers, CASA FOI's etc.

Do you think maybe that many people might actually have a point?

Let me tell you about your theory of putting air traffic controllers concentration closer to the airport - since NAS I can tell you (as a fact) that some air traffic controllers attention is now diverted away from the airport because aircraft need RAS on 1200 VFR on descent where airspae transitions from E to C. Instead of concentrating on the sequence and separating dep with arr with the appropriate level of attention, they are providing suggested headings to inbound aircraft who don't like what their TCAS is telling them - or providing vectors off standard routes to provide desc and climb clear of E airspace all together. Any idea what all this does for enhancing safety?

ATSB don't give you the answer you want: solution - discredit the ATSB.

Do that somewhere else - we are not that stupid.

[Dick Smith]

Howard Hughes, you asked

“how can removing frequencies from charts whilst still expecting people to be on an “appropriate frequency” enhance safety OCTA?”

Safety is enhanced because the system is simpler. Now when flying enroute, if a pilot is in the approach and departure airspace of an aerodrome, they monitor the aerodrome frequency. Where are airline aircraft likely to conflict with VFR aircraft? Yes, in the approach and departure airspace of an aerodrome.

I agree that many of the incidents quoted pre-NAS have aircraft with the wrong frequency selected. Proven overseas systems have shown that if you simplify the system and say to pilots that when in the approach and departure airspace of an aerodrome, monitor the aerodrome frequency, it is such a simple request that it is more often complied with.

I feel sure that you believe that VFR pilots flying enroute in the old system were religiously monitoring ATC frequencies and changing frequency when crossing a radio frequency boundary. You believe this happened, when IFR pilots (who are far more skilled) are told when to change frequency all the time and still make errors.

The old system may have given us a good feeling inside, but compliance was difficult and required pilots to be constantly looking down at charts rather than remaining vigilant.

As over 80% of airports are on frequency 126.7, a pilot can now fly enroute in much of the airspace monitoring 126.7, and be assured of receiving traffic information on aircraft approaching and departing those airports.

People on this forum constantly put down so-called “private pilots”, however incident reports show that all pilots make errors, and the simpler the system, the fewer errors are likely to be made.

I’m sure many will agree.

89 steps to heaven, I'm not sure after 10,000 words of posting what questions I haven't answered. Give me a call on 02 9450 0600 or 0408 640 221 to discuss this. Don't be timid! Bite the bullet and give me a call.

[Dick Smith]

DirectAnywhere, it is extraordinary that you don’t seem to understand my statement:

The reason that unalerted see and avoid incidents will be reduced in MBZ airports is because VFR aircraft flying enroute will no longer be monitoring hundreds of calls which are irrelevant.

This is a statement of fact. In the system before 27 November 2003, VFR pilots were taught to monitor ATC frequencies when enroute – that is why so many people want to keep the ATC frequency boundaries on the charts – and then were taught to change to the MBZ frequency when in the MBZ.

Unfortunately, the evidence appears to show that many pilots got to the MBZ and were then not on the correct frequency. This appears to be a greater problem in Australia (even though the requirement is “mandatory”) than in the US CTAF system, where the problem basically does not exist. They do not have a major problem of unalerted see and avoid at their non-tower airports.

There are two major differences. In the USA there is no requirement for VFR aircraft to monitor a radio when enroute. This means that the US VFR pilot can concentrate on monitoring the airport frequency. Also in the USA, rather than have some airports CTAFs and other airports MBZs, every non-tower airport is treated the same way. There are more self-announcements (seven, in fact) than in our MBZs, and the system results in a very high level of compliance and safety.

The reason we are moving to the NAS system for non-tower airports is not to save money. As you have rightly pointed out, there is no saving. It is to improve safety by reducing unalerted see and avoid incidents. In our system of “radio arranged separation” when VMC exists, the MBZ quickly overloads, and pilots cannot get an announcement in. With the NAS system, because there are more announcements and less dialogue, believe it or not, it can cope with more aircraft in the airport vicinity.

You appear to believe that by moving to NAS style CTAFs that there will be fewer pilots using radio. I do not agree, and if I thought this was the situation I would not support the introduction of NAS. I believe there will be no measurable difference in the number of aircraft using radios when existing MBZs are changed to CTAFs. However there will be less “diffusion of responsibility”, because pilots will be more vigilant.

You do not appear to understand the very great problems we have in existing MBZs. In December 2003, the ATSB completed a report (Airspace-Related Occurrences Involving Regular Public Transport and Charter Aircraft within Mandatory Broadcast Zones) where they made the following recommendation:

Some steps have already been taken in an attempt to increase the safety of aircraft operating within some MBZs. However, airspace-related occurrences within MBZs particularly those relating to radio usage, continue to be of safety concern.

****zu-Tonka, no I do not have an axe to grind with the ATSB. I’m happy that they declared the LT incident an airprox, however I believe it is important that they give the same amount of publicity to other airproxes which are just as serious or even more serious. If they don’t do this, there could be a false understanding that serious safety incidents have actually increased with the new airspace system, when they may have decreased.

The ATSB should be totally objective in their reports. I find it extraordinary that I have listed just some of the many incidents that have taken place over the last few years close to the airport, yet no system safety study has been done by the ATSB which mentions that we have a significant safety problem close to our airports.

[DirectAnywhere]

OK Dick. Sorry, I see your point now but I still don't agree with it. The issue you identify is not one of people monitoring the radio while in enroute airspace but FAILING to monitor the correct frequency when within an MBZ. These are two seperate issues. Incidentally, I agree the majority of calls monitored enroute are irrelevant. However, some aren't; but back to the issue. The second issue - the one you've identified as the problem - should be corrected by better training - not simply by removing the requirement to listen to the radio - either enroute or within a CTAF/ former MBZ under 2c.

Secondly, I do not believe there will be less pilots using the radio but there will be more aircraft, those not equipped with radios, now able to share the same airspace as High Cap. RPT aircraft. Even if an RPT aircraft does sight an aircraft within a 2c CTAF if that aircraft is not radio equipped it becomes a guessing game, based upon "recommended" - not mandatory - procedures as to what that aircraft is going to do.

This opens up a can of worms as a pilot can essentially do what they like - within the bounds of the remaining CARs - and whilst "taking all reasonable steps to ensure that his/her aircraft does not cause a danger to other aircraft". Of course, you need to know the other aircraft is there to do that!!

However, airspace-related occurrences within MBZs particularly those relating to radio usage, continue to be of safety concern.

And sorry, I have to say that again surely this is a training issue. The procedures work fine, so long as people follow them. And whilst I understand your desire to make things simpler, simpler isn't necessarily safer.

One of the major issues I have with Class E as it stands now has already been identified in this thread. Although, the airspace is simpler, and people are making less "errors", as the incident at Launceston has shown, everybody can do everything right and still have an airprox. At least in Class C, someone has to make a mistake for that to happen. I believe the same is true of this proposal.

[DirtyPierre]

Without getting too personal just some points,

1. The incident investigations of all those incidents would have determined a number of causal factors that contributed to the incident occurring. Many of these factors are system based, and some would be based on actual deliberate or accidental non-compliance by aircrew or ATC. Without that reporting by the investigating team, merely listing the incidents has no useful purpose and neither supports nor contradicts your position.

2. You keep mentioning the KISS principle, yet NAS moves Oz airspace to a more complicated airspace design with a greater number of differing procedures (eg. VFR on top, VFR climb/descent, IFR pick-up).

3. I can substantiate S-Tonka's assertion about NAS actually taking the ATC's attention away from his primary tasks of separation. The ATC now has to continually monitor the flight paths of RPT traffic in E airspace even though the ATC has separated the acft from all known traffic. VFR pop-ups on radar occur at anytime, on occasions without height readout. Assessing and passing traffic involves more radio transmissions than separation, consequently taking up valuable ATC thinking time. Radar coverage, even under the J curve, is a patchy thing, thats why ADS-B is being developed.

4. Dick, can you provide any evidence of suitable accredited qualifications and experience in relation to airspace and procedures design, incident investigation, aviation quality assurance, or air traffic management? Being Chairman of a Board might give you management experience, but it doesn't give you specific experience in the core services of that organisation.

5. Did you read the thread started by the Voices of Reason? I noticed you didn't respond. Why?

Dick, like I said before, your heart is in the right place, but leave the professionals to do the job. Well meaning amatuers will never do as good a job as any half decent professional.

Hasta la vista.

People on this forum constantly put down so-called “private pilots”, however incident reports show that all pilots make errors, and the simpler the system, the fewer errors are likely to be made.

Firstly, this is a PROFESSIONAL pilot's forum.

Secondly, we are not putting down private pilot's. We just feel that a private pilot's opinion should not be the deciding factor in determining what is the safest Airspace System for Australia.

[missy]

Dick,

You say "I did not introduce the concept of affordable safety". Whilst that statement in itself may be correct the first time I heard it was from your mouth.

Your tedious posting of 79 Air Safety occurrences prove only one point and that is a human system within which we operate, humans make mistakes. From what I can see NAS does not improve safety.
