What are the parameters for the green, yellow, and red indicators?

A UAS is "UP" (ready) when it is not grounded and has no overdue component replacements, PMs, or custom inspections; yellow means at least one upcoming replacement/PM/inspection. Component/PM/inspection indicators turn red when overdue and yellow when nearing thresholds. Pilot indicators turn red when any certification's days remaining is below 0 and yellow when below 30 days.
