Comprehensibility Testing for Pictogram-based Aircraft Markings and Placards
This SAE Aerospace Recommended Practice (ARP) applies to aircraft markings and placards that are intended to provide information to passengers, crew and ground personnel. When the term placard is used in this document it refers to all markings and placards that are purely based upon pictograms. Text-based markings and placards or markings and placards where text is complemented by pictograms are not in the scope of this document.
Rationale: Standards are in place to describe test methods for pictograms on markings and placards in public areas. This document is intended to give guidance for the consistent definition of test procedures and acceptance criteria for future tests that aim at proving comprehensibility of pictogram-based markings and placards for aircraft.
