Not interested in driving trains or being a NASA astronaut but points taken. I've always said that to colour deficiency has never affected my ability to fly an aircraft. Even if you couldn't tell the PAPI lights what happened to runway situation recognition and for that matter the ILS. Doesn't matter how colourful your glass cockpit is you would still be able to distinguish the the relevent information.
What about when EASA sticks its nose in, how many PPL's will loose their night ratings or instrument ratings.
I was always told you have to be able to see distinct colours mainly White, red, green, never seen that many cloured dots so close together in a cockpit anyway. With modern day communications GPS and alike you would think that we could now fly safely without the need for relying on colour. Runway, approach and taxi way lighting are all distinctive shapes anyway.
You've done it now you lot . I thought I'd left and got rid of all these negative feelings.
