The simplest and most accurate
alternative test is the Farnsworth
lantern (FALANT) test. This is the
preferable test to the other option, the
color signal light test, because FAA
authorization is not required to take the
test. If you pass the Farnsworth, an
unrestricted medical certificate is issued
by the AME. If you wish to obtain a Letter
of Evidence the FAA has a complex
process for this. See a summary of the
requirements here
