FAA regulations generally require aircraft operating with an experimental certificate to display the word EXPERIMENTAL near each entrance to the cabin, cockpit, or pilot station. Under 14 CFR 45.23(b), the letters must be at least 2 inches and no more than 6 inches high.

This 12"W x 2.25"H aircraft placard features 2 inch high EXPERIMENTAL lettering. The characters are permanently engraved into the material rather than printed. The placard is available in contrasting background and character color combinations and has a 3M self adhesive backing for installation.
