Cheers - I've had a look at this sight and it looks good. The example plate tests that are on the site seem remarkably easy (but the site does warn you about this). It is also good to see that the FAA accepts a selction of tests whereas the CAA seems to think along the lines of 'Ishihara or Holmes lantern or bust'.
A previous message explained the FALANT test to me - but surely you will only ever see one of the following selections of nav lights ?
From behind, white, white, white.
From the front,left to right, green,white ( assuming the landing light's on), red.
And from port and starboard only the appropriate red or green and maybe the tail.
This asumes that you are not inverted and at the same altitude as the other aircraft but is the FALANT test a true representation ?
Any thoughts anyone (I haven't done it)?
