Continue, Monitor, Repair or Replace, scored from test result, condition, age, failure history, cost and circuit criticality.
Pick a component, enter its test result and condition, age, failure history, repair cost and how critical its circuit is. The tool scores the evidence and returns Continue, Monitor, Repair or Replace, with the reasons behind the score. The result updates as you type. Add each assessed component to the decision list to print or copy a batch.
Critical circuits get a stricter decision: +2 points.
Placeholder. Set from your specification or datasheet.
Items marked ⚠ are safety-related. A “Poor” rating on any of them leads straight to Replace.
Same currency as repair cost.
No components added yet. Score a component on the Assess tab, then choose Add to decision list.
| ID | Type | Score | Decision | Main reason |
|---|
Score = test result + condition checks + age + failures + criticality. The total maps to a decision, then three overrides can raise it to Replace.
| Factor | Rule | Points |
|---|---|---|
| Test result | Pass / marginal / fail | 0 / 1 / 3 |
| Condition checks | Good / Degraded / Poor | 0 / 1 / 3 |
| Age ÷ design life | ≥ 0.8 / ≥ 1.0 | +1 / +2 |
| Failures, 12 months | 1 / 2 / 3 or more | +1 / +2 / +3 |
| Critical circuit | Selected | +2 |
A minimum-type limit (insulation resistance, light output, luminance) is marginal at 80–100% of the limit and a fail below that. A maximum-type limit (CCR current error) is marginal at 100–125% of the limit and a fail above that.
| Score | Decision |
|---|---|
| 0 – 2 | Continue |
| 3 – 5 | Monitor |
| 6 – 8 | Repair |
| 9 or more | Replace |
Any safety-related check rated Poor gives Replace. If the component is not repairable and the decision would be Repair, or Monitor with a score of 4 or more, it becomes Replace. A Repair decision becomes Replace when repair cost is 60% or more of replacement cost.
The scoring bands, the 60% cost rule and the acceptance limits are starting values for a first decision. Adjust them to your maintenance policy and specification, and treat any safety-related finding as a reason to inspect on site before relying on the score. Light output below 50% of the specified intensity is unserviceable under ICAO Annex 14, so 70% is a planning level.
Quick answers on how the Continue, Monitor, Repair or Replace decision is scored.
It scores a component and returns Continue, Monitor, Repair or Replace, with the reasons behind the score. You pick a component, enter its test result and condition, age, failure history, repair cost and circuit criticality, and the result updates as you type. You can add each assessed component to a decision list to print or copy a batch.
Isolating transformers, connectors and splices, primary cable, light fittings, CCRs and signs. Each has its own test result (for example insulation resistance, light output, output current error or face luminance) and its own condition checks.
Score = test result + condition checks + age + failures + criticality. The test result scores 0 for pass, 1 for marginal and 3 for fail. Each condition check scores 0, 1 or 3 for Good, Degraded or Poor. Age adds +1 at 0.8 of the design life or more and +2 at 1.0 or more. Failures in the last 12 months add +1, +2 or +3 for 1, 2 or 3 or more, and a critical circuit adds +2.
A score of 0 to 2 is Continue, 3 to 5 is Monitor, 6 to 8 is Repair, and 9 or more is Replace. A critical circuit (CAT II or III, stop bars or approach) gets a stricter decision through its +2 points.
Any safety-related check rated Poor gives Replace. If the component is not repairable and the decision would be Repair, or Monitor with a score of 4 or more, it becomes Replace. A Repair decision also becomes Replace when the repair cost is 60 % or more of the replacement cost.
A minimum-type limit (insulation resistance, light output, luminance) is marginal at 80 to 100 % of the limit and a fail below that. A maximum-type limit (CCR current error) is marginal at 100 to 125 % of the limit and a fail above that. The acceptance limit is a placeholder to set from your specification or datasheet.
No. The scoring bands, the 60 % cost rule and the acceptance limits are starting values for a first decision, so adjust them to your maintenance policy and specification.
