What should the slide pressure gauge indicate during preflight?

• A. In the green band
• B. In the red band
• C. In the yellow band
• D. Not connected

Answer: (A)

The main idea here is that you’re confirming normal, ready-to-use system pressure. The slide pressure gauge should be in the green band because that zone represents the normal inflation pressure the slide needs to function correctly. In the green, the slide is properly inflated and ready for deployment if needed. If the gauge shows red, that means the pressure is out of spec—either underinflated or overinflated—which could compromise the slide’s performance or cause damage, so it’s not acceptable for preflight. A yellow band usually signals a caution or borderline condition that requires maintenance or closer inspection, not a confirmed ready state. If the gauge reads not connected, you can’t verify the inflation state at all, which means you can’t confirm readiness. So the correct preflight indication is the green band.
