Guys, I am a Captain with an airline flying jets in the Southern Hemisphere. I have many thousands of hours flight experience and have been flying now for over twenty years. I have not once experienced issues with colour deficiency in my professional aviation career.

I have sat the CAD test and have failed. Previous to this I have sat many colour vision tests, some I have passed and some I have failed. The tests I have consistently passed with 100% pass rate are any practical environmental test. I have passed PAPI test, tower gun tests and a pratical flight test during day and at night, I do not pass the CAD however.

As I have said, I have sat the CAD test and have failed. The CAD test has zero relevance to a pilots environment. For one, it's a synthetic light test done in a synthetic environment asking the applicant to to distinguish rapidly moving coloured targets in the dark after your eyes have had time to adjust. Please explain where in aviation would you ever have to distinguish multiple coloured lights moving rapidly in a controlled synthetic environment? But hey, I'm just a mere professional pilot with no idea about colour and aviation, I should leave that to the non colour deficient, non professional pilots that designed this test.

The CAD test is only good for distinguishing if the applicant is in fact colour deficient, that's all.

As a professional aviator we use an assortment of visual cues to establish whether we are safely "on approach". In the modern day cockpit we have many tools at hand, not just the PAPI lights. We must utilise all the tools at hand to safely fly an approach. On CAT2 and CAT 3B approaches you do not even use the PAPI as guidance. We certainly don't confuse ourselves with rapidly moving lights.

As professional pilots we adjust to our environment, much like colour deficient drivers having to distinguish traffic lights. You might see the lights as a slightly deferent colour, but your brain learns to adapt to your environment of which we work, day in, day out.

Military pilots have been navigating safely on night vision goggles for many years now without incidence. Night vision goggles do not display colour.

I have contributed to the legal challenge in Australia and suggest anyone who is pursuing a professional pilots career in the future should do the same. Google CVDPA.

In the meantime, CASA has written to all potentially affected pilots advising them to consider whether it is safe for them to continue to exercise their flight crew privileges subject only to the existing CVD- related condition, and encouraging them to seek the advice of their personal physician or Designated Aviation Medical Examiner about any adjustments that should be made to their flying practices, pending the outcome of CASA’s review.

"...The AFAP believes it is unreasonable and inappropriate that CASA is asking companies or the affected pilots to make assessments about their ability to hold a medical certificate. CASA issued the medical certificates in question and the affected pilots have been operating under these certificates in good faith.

AOC holders and the pilots themselves are not privy to the "recent medical research" to which CASA refers in its letter nor are they medically qualified to make the assessment requested. If CASA wish to change the regulations regarding colour vision then CASA should follow the correct and established processes. CASA’s letter of 5 June 2014 is in our view an abuse of process.

We request that CASA formally retract the letter of 5 June 2014.

Please also be aware that we will be supporting any of our members who are unfairly discriminated against as a result of CASA’s letter..."

Whygen
Clearly a case of someone in CASA trying hard to justify their job in an era of Federal Budget cut-backs. The irony is that after trying to defend this ridiculousness when challenged in court, they would have cost themselves (ie. us, the taxpayer) hugely and more than likely lost.

old akro Explain to me why the letter from CASA to CVD pilots is not good old fashioned. Bullying? If an employer tried something like this they would be prosecuted in the blink of an eye. Why is CASA exempt?

He wasn't called the 'Screaming Skull' in his last career for no reason. He makes his predecessor 'the Ayatollah' look positively mild by comparison.

these ex-raaf "we know safety" iron circle in CAsA are absolutely insane nutters. there is no other term for their actions in pursuing this senseless bastardry.

What on earth is the problem that Dr Navathe and CASA are expending so much energy trying to solve? It certainly has the close attention of hundreds of Australian pilots as yet another of their number, John O’Brien, prepares to confront CASA’s massive publicly funded legal firepower in the Administrative Appeals Tribunal in a hearing set down for July 21.

The case is scheduled to run for two weeks, and sources close to the matter believe CASA has about a dozen expert witnesses (mostly optometrists) from all over the world and, we’ve been told, has engaged Ian Harvey QC, to parade them before the AAT to convince the Tribunal that aeroplanes will start plummeting out of the sky because some of their pilots, in common with around 8% of the world’s male population, have some degree of colour vision deficiency (CVD).

CASA lawyer Joseph Rule told a recent Senate Estimates hearing that CASA’s costs for this extravaganza had already reached about $43,000, and when pushed a bit more by Senator Fawcett he also admitted to that “It would not be out of the realms of possibility to accumulate another $40,000 in costs.”

Is there $83,000 worth of demonstrably enhanced safety in there somewhere?

Other (usually reliable) sources reckon CASA’s ultimate total costs of running the O’Brien case could stack up to somewhere between $300,000 and $400,000 – not counting John O’Brien’s costs of course, and they’re wondering out loud whether all those dollars might not be better spent scouring global accident history for events that have any statistical link at all with CVD.

Aha! It seems there’s a new development that can maybe shine a little more light into those dark corners. One of Dr Navathe’s colleagues, Mr Peter Fereday at the CASA “Permissions Centre”, wrote to all AOC holders on June 05 that:

“Recent medical research indicates that the safety-related implications of an individual’s CVD may be more significant than they were initially considered to be.

And the following day in a similar letter he told all CVD-affected pilots about the same “recent medical research.”

Our curiosity aroused, we asked CASA’s redoubtable spokesperson Peter Gibson…….

Could CASA please direct me to the references to the original medical research papers that present the evidence referred to in the first and third paragraphs of the attached letter? [That’s Mr Fereday’s letter to AOC holders about CVD.]

…… and after only six days of probing, good old reliable PG bounced right back:

The recent medical research mentioned by CASA in its letter to AOC holders of 5 June 2014 refers to the research described in an article by Dougal B Watson, principal medical officer of the New Zealand CAA [and Dr Navathe’s former boss in NZ], appearing in the February 2014 issue of the Journal of Aviation, Space, and Environmental Medicine.

In May 2014, an article appeared in the magazine Aerosafety World, published by the Flight Safety Foundation, summarising Dr Watson’s research on inconsistencies in the assessment of pilots with CVD.

Enlightenment at last?

Afraid not. It transpires that the article is only available to super-rich people who can afford to commit US$30 (and their credit card details) to a little-known offshore organisation, especially before checking product quality.

However as we were coming to grips with this formidable challenge to astute journalism, a copy of Dr Watson’s treatise fell off the back of a passing truck, and we were back in business.

Or so we thought. But a careful perusal of the document, tantalising titled Lack of lnternational Uniformity in Assessing Color [sic] Vision Deficiency in Professional Pilots, quickly convinced us we must have the wrong bit of paper.

A note attached to the article off the truck had warned:

Take a gander at this rubbish. This [Dr Watson’s treatise] is not evidence of anything of any consequence in this entire debate. Indeed, it is evidence of what a mess the aviation colour perception standard is in worldwide. Imagine relying on this as legal evidence to impress a judge just how dangerous colour vision defective pilots are!

A bit harsh? Well not really. If I were Mr Fereday (or Peter Gibson) I’d be quietly seeking a second opinion before I passed on anything originating from the source of those assertions. Let’s remind ourselves:

“Recent medical research indicates that the safety-related implications of an individual’s CVD may be more significant than they were initially considered to be.”

Can CASA point out any recent research presented in the Watson article that indicates anything of the sort?

As anybody familiar with the debate would observe, the Watson prose is packed with subjective assertions, mind-numbing statistics, tables and flow charts that are in no way relevant to the “safety-related implications of an individual’s CVD”. In fact they don’t depict any safety-relevant medical research, and are in bad English, exacerbated by American spelling. The reason Watson doesn’t refer to relevant accident statistics (because there aren’t any) and his article comes up with just two not quite earth-shattering assertions that actually admit in its two listed findings:

“The main conclusions from this research are that:

There is a high degree of variation between States in the detection and medical assessment of CVD applicants; and

The observed variation stems not from the wording of the medical standards of the States, but from the application of those standards.

So 190 separate states have all figured out different but similar satisfactory ways of managing the same issue, right?

Furthermore Dr Watson’s research actually refers to:

the paucity of documented aircraft accidents or incidents where CVD is implicated as a contributory factor.” [Because there are none]. And states that:

It is beyond the scope of this report to analyze [analyse] the issues and the debates concerning CV standards and civil aviation”.

So! Dud information has been unintentionally passed back to us via CASA PR?

We haven’t yet seen any AOC-holder response to Mr Fereday’s June 5 letter, but its next-day follow-up to pilots has already caused at least one pilot body to reach for its keyboard and mouse. The Australian Federation of Air Pilots has directed a sharp response from its President Capt Bryan Murray to current CASA CEO John McCormick:

Dear Mr McCormick,

Re: Colour Vision Deficiency (CVD)

I am writing on behalf of the AFAP to express our concern over the letter dated 5 June 2014 from Peter Fereday to AOC holders regarding Colour Vision Deficiency (CVD).

The AFAP believes it is unreasonable and inappropriate that CASA is asking companies or the affected pilots to make assessments about their ability to hold a medical certificate. CASA issued the medical certificates in question and the affected pilots have been operating under these certificates in good faith.

AOC holders and the pilots themselves are not privy to the “recent medical research” to which CASA refers in its letter nor are they medically qualified to make the assessment requested. If CASA wish to change the regulations regarding colour vision then CASA should follow the correct and established processes. CASA’s letter of 5 June 2014 is in our view an abuse of process.

We request that CASA formally retract the letter of 5 June 2014.

Please also be aware that we will be supporting any of our members who are unfairly discriminated against as a result of CASA’s letter.

Meanwhile nowhere has CASA attempted to express in cost benefit terms, the safety benefits its proposed actions would deliver. So what is the problem to which all that public expense is supposed to be the answer? Where’s the history? Where are all the accidents that are linked to CVD pilots?

Although there isn’t any such history, there’s plenty that covers related legal activity.

In October 1987 the AAT reviewed a negative decision by the (then) Civil Aviation Authority that had been made in respect of Dr Arthur Pape, a licensed pilot, medical practitioner and DAME, and recognised as a world expert on colour deficiency in aviation. However the AAT decision was only in respect of Dr Pape’s private pilot licence, and imposed restrictions related to aircraft equipment, night flying, maximum takeoff weight and cruising speed, but and weather conditions.

18 months later in April 1989 the Tribunal heard another application by a CVD pilot, this one from commercial pilot Hugh Denison, a young colour defective pilot who had qualified for night flight in New Zealand, but who was prohibited by the CAA from night flight in Australia.

To quote Dr Pape, whose interest in these issues has never wavered:

“Again, the appeal succeeded and the ban on night flight was overturned for all colour defective pilots in Australia. To this date, the Denison appeal is still the most comprehensive examination of aviation colour vision standards that has ever been conducted in the entire world. The hearings lasted for over 30 days and called witnesses including experienced pilots and air traffic controllers, optometrists and visual perception psychologists to name just a few. As a direct result of the appeal’s success, many such pilots found doors opening to career opportunities that were previously denied to them”.

This AAT hearing resulted in an order that:

The decision under review is set aside and, in substitution for it, it is decided that the applicant is to be granted, under regulation 63 of the Civil Aviation Regulations, a commercial pilot licence to fly fixed wing aircraft and rotary wing aircraft, the said licence to be subject to only the following two conditions:-

(1) That he is not permitted to pilot an aircraft in international air navigation except with the permission of the appropriate authority of the country concerned;

(2) That he is not permitted to pilot aircraft within control zones unless the aircraft being flown is fitted with radio apparatus such that he can maintain two-way communication on appropriate frequencies.

In a detailed analysis of its decision, the Tribunal explained that it was running a “test case” and it also explained why:

“We understand that there are a considerable number of other pilots with defective colour vision who have requested the granting of licences which do not contain a condition prohibiting their piloting aircraft at night. For that reason the respondent [CASA] indicated that it wished to conduct this case as a test case.

“Mr Rose [Appearing for CASA], therefore, informed the Tribunal that the respondent intended to present its case in a manner which would encompass not only the applicant’s situation but also broader issues relating generally to defective colour vision. At the request of the respondent [CASA] the Attorney-General granted legal aid to the applicant to ensure that he was not disadvantaged by the respondent presenting his case in that manner.

“The matters which we have to consider in these proceedings have consequently been extended well beyond those which the applicant [Mr Denison] originally sought to raise, that is to say whether his defective colour vision made it unsafe for him personally to pilot an aircraft at night.

Costs to the various parties in the Denison case have not been identified, but the AAT discussed in great detail the whole procedure it had adopted, all of the issue-related questions asked and answered, the witnesses, areas in which there was broad agreement, types of CVD, the technologies used in assessing it, and its safety relevance in flight operations at all levels. The decision document also contains detailed analysis of every related issue discussed by witnesses and laid the foundations for about 15 years of relative truce. The ruling was accepted by all parties and has been the basis under which CVD pilots have been operating successfully until CASA resumed hostilities.

The last two paragraphs of the AAT decision are relevant to Mr O’Brien’s case:.

78. We recommend that suitable practical tests should be devised so that a protan [Mr O’Brien’s condition] can be tested individually, if he wishes, at his own expense to ascertain the extent of the loss of his ability to perceive the intensity of red lights. If his distant visual acuity is such that, when allowance is made for the loss of ability to perceive the intensity of red lights, he is able to see red lights at the furthest distance that they can be seen by persons who have normal colour vision and the distant acuity required by ANO 47.1.2.13 or ANO 47.1.3.13, as appropriate to the type of licence sought, a licence should be granted to him under regulation 63 subject to only the two conditions referred to above. If a change in his visual acuity is detected thereafter in the course of any routine medical examination, he should be required to undergo the practical test again. Otherwise a licence granted to a protan under regulation 63 should be subject to the additional condition that the pilot does not fly an aircraft at night.

79. Finally, while recognising that the Tribunal has no power to review decisions of the Authority to set medical standards under regulation 62, we suggest that protanomals ought not to be totally prevented, as they are at present, from meeting the colour vision standard. It appears from Dr Samuel’s evidence that some persons with mild protanomaly are able to perceive the existence of red lights at a distance which is as great as, or greater than, the furthest distance at which a person with normal colour vision and distant visual acuity of 6/6 can do so. We suggest that the colour vision standard be altered so as to permit such mild protanomals to take the Farnsworth Lantern test and, if they pass it, to meet the standard and so be qualified, so far as colour vision is concerned, for the grant of an unconditional licence.

Those two paragraphs go to the heart of Mr O’Brien’s situation and that of many others who are now threatened despite thousands of hours of uneventful flight.

It is completely untruthful to assert as CASA has, that there is anything in Dr Watson’s paper to suggest that individuals’ CVD pilot issues “may be more significant than they were initially considered to be.”

The only thing that has changed on the CVD scene since the AAT delivered its comprehensive analysis, findings and recommendations, has been the accumulation of several million more flying hours by CVD pilots without a CVD related accident. The person or persons responsible for this attempt to wind back the clock needs to be held accountable for their actions.

If CASA’s recruiting consultancy identifies a CEO candidate who meets all the key qualities it is seeking in terms of experience, critical competencies for success and other attributes, the newcomer will easily see this campaign for what it is.

A return to reality on CVD issues might then be one of the many early outcomes sought by the 269 contributors to the ASRR.

An important footnote

We would point out that there has in fact been one case where CVD got a mention in an accident investigation; however its CV relevance is widely disputed.

On July 26, 2002, a Boeing 727-238F freighter collided with trees on short final and crashed short of the runway at Tallahassee, Florida. The NTSB report said:

The National Transportation Safety Board determined that the probable cause of the accident was the captain’s and first officer’s failure to establish and maintain a proper glidepath during the night visual approach to landing. “Contributing to the accident was a combination of the captain’s and first officer’s fatigue, the captain’s and first officer’s failure to adhere to company flight procedures, the captain’s and flight engineer’s failure to monitor the approach, and the first officer’s colour vision deficiency.”

However the text of the NTSB report contained no supporting discussion of CVD or its role in the accident, and did not explain why both the captain and the flight engineer (who was also a pilot,) reported seeing the same displays on the PAPI as the co-pilot did.

when we were discussing the CAsA bastardry the other night in the clubhouse I named the 5 pilots. none in my presence could believe that they had any impairment.
they are 5 of the best pilots in the club.

BTW, what colour do night vision apparatus, CVD or non CVD pilots see as grass?

We're not grounding any pilots, we're not putting any further restrictions on any pilots, we're simply saying there is some new information out there which we're considering.
