Comprehensibility Testing for Pictogram-Based Aircraft Signs and Placards
This SAE Aerospace Recommended Practice (ARP) applies to comprehensibility testing of aircraft markings, signs, and placards that are intended to provide information to passengers, crew, or ground personnel exclusively through pictorial symbols (pictograms).
Markings, signs, and placards where text is complemented by pictograms are not in the scope of this document. In case text and pictograms are used in a redundant manner, comprehension testing is not required.
Standards are in place to describe test methods for pictograms on markings, signs, and placards in public areas. This document is intended to give guidance for the consistent definition of test and acceptance procedures that aim at proving comprehensibility of pictogram-based markings, illuminated signs, and placards for aircraft.
