Every aircraft needs context.
A tail-specific operating record tells you what happened. Model Intelligence shows whether that record is typical for the model.

Diligence question
What explains the difference?
A question to investigate, not a diagnosis
Evidence and methodology
A benchmark you can inspect.
Every comparison shows which aircraft were included, how the population was defined and where the evidence has limits.
Eligible population
The report defines which aircraft and observations are included.
Consistent basis
Comparable aircraft are assessed using the same measurement rules.
Coverage and confidence
Population size, observation period and data coverage are shown.
Traceable method
Definitions, calculations and assumptions can be reviewed.

Frequently asked questions
Before you request a report.
The essentials, answered directly.
Which aircraft models are available?
Reports are available where tracked activity is sufficient to define a meaningful eligible population. We check coverage before confirming a request.
How is the eligible population defined?
Aircraft of the same model are assessed over the same trailing 12-month window. Each tail must have at least 12 tracked movements to be ranked.
How is this different from TailCheck?
TailCheck examines the operating record of a specific aircraft. Model Intelligence places that aircraft within the wider operating population for its model.
Does the report diagnose aircraft condition?
No. It shows position, difference and distribution. It does not establish mechanical condition, maintenance cause, value or future performance.
