HUD Low status is represented by what, and what is the pressure range?

• A. Flashing red continuously until shutdown or 200 PSI 35%-0%
• B. Solid red 0%-35%
• C. Solid yellow 0%-35%
• D. Flashing green 0%-35%

Answer: (A)

HUD Low status shows as flashing red, grabbing your attention when air is running low. It stays flashing red until one of two things happens: you shut the system down, or the cylinder pressure reaches 200 psi. This flashing signal communicates urgency and the need to take immediate action, such as switching to a backup or exiting the area. The low-air window is defined from 35% of cylinder pressure down to 0%. That means as soon as remaining air drops to 35%, you enter the Low status, and the indicator continues flashing all the way down to empty. The 200 psi point is a training/operational cue that marks a concrete action threshold within that low range. The other color statuses (solid red, solid yellow, flashing green) correspond to different conditions and don’t describe the Low status in this context.
