What is the preflight check for a solid-state oxygen unit?

• A. Location and white temperature-resistant sticker outside unit
• B. Battery level
• C. Expiration date
• D. Color of seal

Answer: (A)

In preflight checks for a solid-state oxygen unit, the priority is to confirm the device is in the correct place and properly labeled so you know it’s the approved unit and still within safe operating conditions. Checking the location ensures the unit is where it’s supposed to be for proper use, accessibility, and integration with the system. The white temperature-resistant sticker outside the unit provides a quick, visible indication that the device has been reviewed for temperature safety and identification, helping prevent use of a unit that’s been exposed to conditions that could affect performance. Battery level isn’t inherently applicable to every solid-state oxygen unit, and expiration dates are more relevant to consumables or specific components rather than the basic safety and placement status. The color of a seal is a tamper-evident feature, but it doesn’t convey whether the unit is correctly located or within safe temperature parameters.
