Just bringing this to the top again.
I have just returned from City University where I spent a couple of hours doing Dr Squire's various colour tests including her new computer based test being developed to try and remove any subjectivity from the pass fail issue.
Dr Squire's is, as Phil Smith said, doing some research for the CAA who are now begining to think the existing tests may be too hard and may not reflect the requirements of current aviation. She is interested in testing for the purposes of her research both colour defective and normal colour vison pilots and is especially keen to hear from anyone flying commercialy with any type of colour defects.
In order to fully develope their new colour testing computer programme, they have all the traditional colour testing lanterns known to mankind which she will use to validate their own computer test.
In addition to the colour tests she is interested to hear what views pilots have on the colour question, for example if (like me) you are colour defective in some way, how and to what exent does this impact on your actual flying and what if any compensatory actions do you take to overcome the defect. Is colour really that important in aviation?
I found it totally fascinating and learnt a lot about the extent of my colour defectivness, something no one has really been able to explain before and so it was well worth a visit just for that. It may also help future wannabes if the tests are changed to be less difficult or more relevant.
If you are interested in taking part, I recommend that you conatct Dr Squire on the e mail address in Phil's earlier post, preferably within the next couple of weeks as one of the lanterns they have on loan has to go back to Switzerland!
