This reference covers all crew scheduling data types, statuses, and regulatory constraints used across the Operations module.

Duty Time Limits
PlaneConnection monitors the following regulatory flight time and duty limits. These values reflect the standard 14 CFR Part 135 Subpart F limits. Your operator’s OpSpecs may impose stricter limits.
14 CFR Part 135 Subpart F (Flight Time Limitations)
| Rule | Reference | Limit |
|---|
| Daily flight time (1 pilot) | 14 CFR 135.267(b) | 8 hours in any 24 consecutive hours |
| Daily flight time (2 pilots) | 14 CFR 135.267(b) | 10 hours in any 24 consecutive hours |
| Weekly flight time | 14 CFR 135.267(c) | 34 hours in any 7 consecutive calendar days |
| Minimum rest before duty | 14 CFR 135.267(d) | 10 consecutive hours of rest before beginning duty |
| Rest after exceeding 8 hours | 14 CFR 135.267(d) | 13 consecutive hours of rest after exceeding 8 hours of flight |
14 CFR Part 117 (Additional Limits)
| Rule | Reference | Limit |
|---|
| 28-day flight time | Part 117 | 120 hours in any 28 consecutive days |
| 365-day flight time | Part 117 | 1,000 hours in any 365 consecutive days |
Compliance Status Indicators
The system displays compliance status using the following thresholds:
| Indicator | Condition | Action Required |
|---|
| Green | Under 80% of any applicable limit | No action needed |
| Yellow | Between 80% and 95% of any applicable limit | Monitor closely before assigning |
| Red | Above 95% of any applicable limit | Do not assign additional duty |
Currency Items
Six currency items are tracked for each crew member:
| Item | API Value | Regulatory Basis | Warning Window |
|---|
| Medical | medical | 14 CFR Part 135 Subpart E | 60 days |
| BFR | bfr | 14 CFR 61.56 (Biennial Flight Review) | 60 days |
| IPC | ipc | 14 CFR 61.57(d) (Instrument Proficiency Check) | 60 days |
| Type Rating | type_rating | 14 CFR Part 61 Subpart H | 60 days |
| Recurrent | recurrent | 14 CFR Part 135 Subpart G | 60 days |
| Status | API Value | Meaning |
|---|
| Current | current | Expiration is more than 60 days away. |
| Expiring Soon | expiring_soon | Expiration is within 60 days. |
| Expired | expired | Expiration date has passed. |
Expired currency items block trip assignment at the Confirmed status. A crew member showing any
expired item cannot be added to a trip leg that requires the expired qualification.
Schedule Assignment Types
Administrators can create custom assignment types that appear on the crew schedule grid. Each type has configurable properties:
| Property | Type | Description |
|---|
| Name | String | Display name (e.g., “Simulator Training”, “Office Day”). |
| Color | String | Hex color code for the schedule grid. |
| Flight Conflict | Boolean | If true, blocks flight trip assignment on overlapping days. |
| Terminates RON | Boolean | If true, ends a remain-overnight sequence. |
| Day of Work | Boolean | If true, counts as a working day for duty calculations. |
| Sort Order | Number | Display order in selection lists. |
Crew Roles
| Role | API Value | Flight Time Tracked | Duty Time Tracked |
|---|
| PIC | pic | Yes | Yes |
| SIC | sic | Yes | Yes |
| Flight Attendant | flight_attendant | No | Yes |
| Dispatcher | dispatcher | No | Yes |
| Mechanic | mechanic | No | Yes |
| Relief Pilot | relief | Yes | Yes |
Fatigue Risk (K-Score)
The fatigue risk score is computed per AC 120-103A (Fatigue Risk Management Systems). See How to Use Crew Intelligence for interpretation guidance.
| K-Score Level | Range | Meaning |
|---|
| Low | 0 — 30 | Normal fatigue levels. |
| Moderate | 31 — 60 | Elevated — monitor before assignment. |
| High | 61 — 80 | High risk — review before proceeding. |
| Critical | 81+ | Do not assign without rest intervention. |
