Type of Ishihara at Gatwick?
Hi,
Anyone know whether the Ishihara plates used at Gatwick CAA medical office are the 24- or 38-plate variety?
I've applied for the ICAO Extended Renewal JAR Class 1 medical. I meet the Canadian minimum standard which is the Farnsworth D-15 test, a series of coloured disks you have to arrange in order from purple to turqoise.
However I routinely fail the Ishihara test, and am trying to "get used" to the plates. If anyone else is in the same boat, the 24-plate Ishihara is online at http://www.kcl.ac.uk/teares/gktvc/vc/lt/colourblindness/cblind.htm
Also, apparently there are (very!) tiny numbers on the real Ishihara plates, from 1-24 in series that match 1-24 on the online test above.
