Comprehensive Guide to Airservices MET CDM Rate Calculator
The Airservices Meteorological Charge Differential Mechanism (CDM) is a sophisticated pricing model designed to ensure equitable cost recovery for meteorological services provided to airspace users. This guide explains how the CDM works, its components, and how to use our calculator effectively.
Understanding the MET CDM Structure
The MET CDM consists of several key components that determine the final charge:
- Base Charge: A fixed component based on aircraft type and flight phase
- Fuel Component: Variable charge based on fuel consumption
- Distance Component: Charge proportional to distance traveled
- Service Level Adjustment: Additional charges for priority or emergency services
Aircraft Classification and Base Rates
Aircraft are categorized based on Maximum Takeoff Weight (MTOW) which directly impacts the base charge:
| Aircraft Category | MTOW Range | Base Rate (AUD) | Examples |
|---|---|---|---|
| Heavy | >136,000kg | $125.40 | Boeing 747, Airbus A380 |
| Medium | 7,000kg – 136,000kg | $62.70 | Boeing 737, Airbus A320 |
| Light | <7,000kg | $31.35 | Cessna 172, Piper PA-28 |
| Helicopter | All weights | $25.08 | Bell 412, Airbus H135 |
Fuel Consumption Component
The fuel component is calculated at $0.012 per kilogram of fuel consumed. This reflects the meteorological services required for fuel planning and en-route weather updates. For example:
- 500kg fuel consumption = $6.00 component
- 2,000kg fuel consumption = $24.00 component
- 10,000kg fuel consumption = $120.00 component
Distance-Based Charging
The distance component applies to overflights and international flights at $0.55 per nautical mile. Domestic flights within Australian airspace are exempt from this component.
Service Level Adjustments
Different service levels attract additional charges:
| Service Level | Adjustment Factor | Typical Use Cases |
|---|---|---|
| Standard | 1.0× | Regular commercial flights |
| Priority | 1.3× | Medical flights, VIP transports |
| Emergency | 1.7× | Search and rescue, disaster response |
Practical Calculation Example
Let’s calculate the MET CDM for a medium aircraft (Boeing 737) on an international arrival:
- Base Charge: $62.70 (medium aircraft arrival)
- Fuel Consumption: 3,500kg × $0.012 = $42.00
- Distance: 1,200NM × $0.55 = $660.00
- Service Level: Standard (1.0×)
- Total: $62.70 + $42.00 + $660.00 = $764.70
