"I did my class one medical i was asked to read the 4th line which was fine and 5th line which i did but with some strain. However i couldn't read the bottom line. Could anyone guess, to tell me what my eye-sight is?"
Depends on the chart but I think the 5th line would normally be 20/15 or 6/4.5 which is fine for JAR or FAA class 1. The doc at Bascom Palmer tells me the military pilots she has seen are all 20/10 (6/3) - they can read the bottom line with no problems. Even after $5k of surgery I cant read that line at all.
