What the Agent classifies

Multiple agreements, one Agent

Aviation payroll involves multiple collective agreements per jurisdiction - pilot unions for cockpit, cabin crew unions, ground handling unions - plus EASA flight time limits and international per diems. (UK: Post-Brexit, UK CAA retained EASA FTL. BALPA, Unite, and GMB negotiate separately for cockpit, cabin, and ground.) You know the complexity. Here is how the AI Agent resolves it:

Cockpit: seniority bands and pay scales

Pilot collective agreements cover multiple seniority bands from Second Officer to Senior Captain, fleet-specific rates, and pension contributions. The AI Agent identifies the current seniority band and fleet assignment from the employee master record and maps to the correct pay scale. On promotion from First Officer to Captain, the new band applies automatically.

Cabin: shift premiums and flying pay

Base pay plus shift premiums, purser allowances, and per diems by rotation plan. The AI Agent distinguishes short-haul from long-haul and calculates the correct per diems and duty patterns per rotation. On route changes: automatic recalculation.

Ground: handling agreements and premiums

Multiple pay frameworks covering check-in, ramp, baggage, and cargo, each with night, weekend, and bank holiday premiums. The AI Agent classifies pay grade and experience level from the employee master record and job profile - including when staff rotate between check-in, ramp, and baggage handling.

EASA FTL: flight time limits as payroll boundary

EASA Flight Time Limitations define hard limits: maximum 900 flight hours per year, Flight Duty Period maximum 13 hours. The AI Agent checks every payroll cycle against these limits and escalates when thresholds are approached. Exceeding limits risks licence revocation and fines - that is no longer a payroll question, it is a legal one.

Per diems: 180+ country rates

A London-Dubai-Singapore rotation: three country rates in a single duty period. The AI Agent calculates meal and incidental expenses per rotation segment based on national tax authority rates per jurisdiction, including meal deductions and minimum stay durations. On IROP-related rotation changes: automatic recalculation. The same logic also powers travel expense processing in the Travel Decision Layer.

One aviation payslip. 50 to 120 micro-decisions.

A long-haul captain. The Payroll Decision Layer breaks down their payslip into individual decision steps:

Step	Decision	Decision maker	Rationale
1	Classify personnel group	AI Agent	Agent identifies: cockpit, cabin, ground, or maintenance from master data and position key
2	Assign collective agreement	AI Agent	Agent maps to: pilot union, cabin union, or ground handling agreement. Additionally: which airline entity (group subsidiaries have separate agreements)
3	Calculate base pay	Collective agreement	Lookup in versioned pay scale: seniority band, fleet, experience level
4	Calculate shift premiums	Collective agreement	Cabin: shift and flying pay premiums. Ground: premiums per shift model. Cockpit: integrated in base pay
5	Check FTL compliance	Rule engine	EASA FTL check: 900h annual cap, FDP max. 13h, cumulative limits. Escalation on approach
6	Classify per diem	AI Agent	Agent classifies rotation: which countries, what duration, which per diem rates apply
7	Calculate per diem	Rule engine	Per diem rates per national tax authority, meal deduction, minimum stay. On IROP changes: automatic recalculation
8	Calculate pension contributions	Rule engine	Occupational pension, airline pension fund. Deterministic per agreement
9	Variance check	AI flags, human decides	AI detects variances more reliably. But the assessment stays with a human - Employment law requires transparency in pay governance
10	Generate journal entries	Rule engine	FI/CO posting, multi-entity (group subsidiaries), cost centre - deterministic

Simulation

Calculated for aviation volumes

We configured the Payroll Decision Layer with realistic aviation parameters and ran the simulation. Multiple collective agreements, EASA FTL, international per diem rates, cockpit seniority across multiple bands.

Simulation parameters

Crew strength	10,000 to 50,000+ (cockpit, cabin, ground, maintenance)
Parallel agreements	2 to 5 (pilot, cabin, ground, plus subsidiary-specific agreements)
Jurisdictions	Multi-jurisdiction (home base UK, stations EU/worldwide)
IROP rate	10-20% (irregularities with payroll impact)
Per diem countries	180+ country rates per national tax authority
Cockpit seniority bands	Multiple bands (Second Officer to Senior Captain), pension contributions

Before / After

Dimension	Manual	Decision Layer
Error rate	3-12% (APA, aviation uplift)	< 0.3%
Zero-touch rate	0%	82%
Per diem calculation	Manual per rotation, error-prone	Automatic, 180+ countries
FTL compliance	Separate check, after the fact	Integrated, real-time limits
Agreement renewal (3 unions)	Weeks per union	< 24h (all in parallel)
Audit readiness	Manually reconstructed	Automatically generated

APA: American Payroll Association. Aviation collective agreements 2024. EASA EU Reg. 83/2014. National per diem rates 2024. Simulation results: Gosign model calculation.

In our simulation, the Decision Layer achieves a zero-touch rate of 82%. The remaining 18% are genuine exceptions: IROP-related rotation changes, union switches during group transfers, FTL threshold cases requiring escalation, cockpit promotions crossing agreement boundaries. For the 82%, a complete, audit-ready decision record is available.

Architecture and implementation

The Payroll Decision Layer runs entirely within your infrastructure. For aviation, this means: integration with crew management systems, processing of rotation plans and FTL data, three parallel agreement frameworks, and a complete audit trail through to SAP HCM. Typical pilot projects launch within 3 months with one personnel group and one collective agreement.

Frequently Asked Questions about the Aviation Configuration

How does the Decision Layer distinguish between multiple union agreements?

Airlines negotiate with multiple unions: pilot unions for cockpit, cabin crew unions, ground handling unions. The AI Agent classifies each employee based on their personnel group: cockpit, cabin, or ground. The assignment is derived from the employee master record and position key. Each union has its own pay scales stored as versioned Decision Tables. When an employee moves between groups, the correct agreement applies automatically.

How are the 180+ country per diem rates processed?

Per diem rates follow national per diem rates as the baseline, alongside country-specific rate tables for international operations. The AI Agent classifies the rotation: which countries were flown to, how long was the layover? The rule engine calculates the daily rate deterministically. Meal deductions are applied automatically. When rotations change due to IROPs, the system recalculates.

How is EASA FTL compliance reflected in payroll?

EASA Flight Time Limitations define hard limits: maximum 900 flight hours per year, Flight Duty Period maximum 13 hours. The AI Agent checks every payroll cycle against these limits. When approaching a threshold, a Human-in-the-Loop escalation is triggered automatically. Compliance checks are documented in the audit trail.

Can the Decision Layer map cockpit seniority across multiple pay bands?

Yes. Cockpit compensation under pilot collective agreements typically includes multiple seniority bands from Second Officer through to Senior Captain. The AI Agent identifies the current band from the employee master record. The rule engine calculates base pay, band progression, and pension contributions deterministically. On promotion from First Officer to Captain, the new pay scale applies automatically.

What happens during IROPs (Irregular Operations)?

IROPs such as flight cancellations, diversions, or crew repositioning change per diems, shift premiums, and FTL calculations. The AI Agent detects IROP changes from crew management data. The rule engine calculates the impact on compensation and allowances. With IROP rates of 10-20%, that means hundreds of recalculations per month.

Is the system compatible with employee representation requirements?

Yes. Employment law requires transparency in pay principles. The Payroll Decision Layer makes all agreement frameworks visible and every decision traceable. The AI classifies facts but does not calculate salaries - deterministic rule engines do. Employee representation bodies (such as works councils, trade unions, or pilot associations) can trace every decision.
