• Mounted near equipment or panels to remind the crew of operating limits or procedures. Ensure correct text and location per the maintenance manual.
  
  

• Used to mark access panels or compartments so crew/passengers can quickly locate them in emergencies. Confirm legend matches the intended function.
  
  

• Placed adjacent to cabin or service doors with instructions like “PULL TO OPEN,” “PUSH TO CLOSE,” or location identifiers, assisting crew in correct operation.
  
  

• In ground-based trainers or cabin mock-ups, identical placards help simulate real aircraft environments for training crew in recognizing and responding to signage.

• What material is used, and is it fire-retardant?

Aircraft placards are typically made from fireproof metal or flame-retardant polycarbonate/film substrates meeting FAR 25.853/EASA equivalents. They use aviation-strength inks or metal photo processes to ensure flame resistance and durability.

• Can I store these placards long-term before installation?

Yes, store in a clean, dry environment at room temperature, away from direct sunlight and solvents. 

• How do I ensure the printed legend remains legible over time?

Use placards with durable inks or etching processes rated for abrasion and cleaning agents. During maintenance inspections, check for fading, scratches, or peeling; replace any placard showing degraded legibility to maintain safety compliance.
