Compliance
Every rule carries its source.
A flight’s eligibility is checked against real rules (medical validity, rating currency, recent experience) and each one clears with the regulation it comes from, so the decision is auditable rather than remembered.
Eligibility · Capt. Reid + 1
Northstar- Class 2 medical valid MetPart-MED · to 2027-03-14
- SEP class rating current MetPart-FCL · to 2026-11-30
- Passenger recency, 3 in 90 days MetPart-FCL.060
Every check records the rule it applied and the moment it was made
A flight’s eligibility is checked for Capt. Reid carrying a passenger. Three rules clear in turn (a valid Class 2 medical under Part-MED, a current SEP class rating under Part-FCL, and passenger recency of three take-offs and landings in 90 days under Part-FCL.060), each shown with its source, and the flight is cleared to fly.
Rules are data, not code.
Medical validity, rating currency and recent-experience rules are configured with their regulatory basis and effective date, so when a rule changes, you change the rule, not wait for a release.
Checked with the reason.
When a flight is cleared or held, each rule shows the regulation it applied (Part-MED, Part-FCL, the recent-experience rule) and the date that basis took effect. Nothing is a private judgement.
The audit trail is automatic.
Every check records the rule it applied and the moment it was made. When a standardisation visit asks how you knew a pilot was eligible, the answer is already written down.
Your exposition, not ours.
The rules follow your approved or declared procedures, with their source and jurisdiction, so the system helps you operate your exposition. It does not impose a generic one or claim an approval it cannot give.

The cost
“We just know” is not an answer to an auditor.
Eligibility usually lives in experienced heads: who’s current, whose medical is due, who needs a check ride. It works until the person is away or the auditor asks how you knew. FlyerOS makes the rule explicit and records every decision against its source, so the knowledge is the system’s, not one person’s.
