Who is typically authorized to apply range markings to an instrument dial face?

• A. Apprentice technician
• B. Certified airframe mechanic
• C. Flight instructor
• D. Aerospace designer

Answer: (B)

Range markings on an instrument dial face are maintenance work that must be done by someone with proper certification and authorization to perform aircraft systems maintenance. A certified airframe mechanic has the training and legal authority to apply markings and calibrate instrument components according to approved data and manufacturer specifications. An apprentice technician isn’t yet certified to perform such tasks; a flight instructor’s role is teaching rather than maintenance; and an aerospace designer focuses on design, not performing field maintenance. This is why a certified airframe mechanic is the appropriate person to handle range markings.
