CAD Testing
Hi guys,
Cliche as it sounds, I've always wanted to become pilot ever since I was a little kid.
Upon discovering that I was CVD I decided to stray away from this industry. Having recently completed a bachelors degree I realised that with my CVD condition, purusing a career may be possible. Thus having gone to my aviation medical examiner- as expected I've passed all other components of the test (for a Class 1 Medical) however failed the ISHIHARA plate tests. Subsequently I was directed to the fansworth test which I had failed as well with a 'severe deficiency' result. Thus I've recently scheduled a CAD test (a make or break for me).
Thus I have a few questions:
How can I practice for the CAD test?
What does it involve?
Has anyone attempted this test before? What is the pass/fail rate of the test?
To my understanding a Class 1 Medical is required for any remunerated work in Australia.
If I fail this component am I eligible for a Class 1 Medical-with restriction to day time flying only. Realistically what are my career prospects with this restriction in Australia?
Any assistance would be greatly appreciated!
Thanks in advance.

Accuracy of CAD Test
How accurate is the CAD test? My son has failed it miserably even though he was told to guess if needs be! I can’t understand how any test, where responses are guessed can provide an accurate and reliable result 🤔 Thank you for any feedback you can provide.

The CAD is an accurate way of diagnosing and quantifying levels of colour vision deficiency.
Here's what it looks like: https://youtu.be/Jgq6Qhy2FQk?si=kZTa...Taia43P7sx_Hxo
Spot the big coloured squares traversing the little grayscale squares.
