Part 121	`part_121`	14 CFR Part 121 operations
Training	`training`	Training flights
Check Ride	`check_ride`	Proficiency or type checks

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

Currency status values:

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.
