Airservices En Route Chart - Low Altitude (ERC Low)

Effective Date: 09 July 2026
Airspace: Up to FL200

When you transition from departure to the cruise phase of flight, clear and structured en-route data is critical. Airservices Enroute Charts (ERC) are the definitive Australian standard for instrument flight rules (IFR) navigation and flight planning, providing essential airway, frequency, and airspace data across the continent.

Available in both Low Altitude and High Altitude formats, these charts ensure you have the exact level of detail required for your specific flight level.

Available Charts:

L1/L2 - Melbourne, Hobart, Adelaide, Sydney
L3/L4 - Sydney, Brisbane, Brisbane, Townsville
L5/L6 - Townsville, Broken Hill, Mount Isa, Darwin, Townsville, Port Hedland
L7/L8 - Adelaide, Alice Springs, Caiguna, Perth, Pert Hedland, Caiguna

ERC Low (Low Altitude) - More Information:

• Operational Level: Designed for flights operating at lower altitudes (typically below FL200).
• Best For: Piston twins, turboprops, and light aircraft operating under IFR or VFR pilots looking for comprehensive radio navigation data.
• Key Details: Features low-level ATS routes, holding patterns, minimum en-route altitudes (MEA), VHF/LF navigation aids, and Class E airspace boundaries.

Key Features & Operational Value

• Comprehensive Airway Networks: Clearly marked air routes, track distances, and bearings for seamless navigation and flight plan filing.
• Vital Frequency Data: Quick-access information for Center, Flight Information Services (FIS), and CTAF/AFRU frequencies.
• Airspace & Restricted Zones: Clear visualization of Controlled Airspace (CTA) steps, Prohibited, Restricted, and Danger (PRD) areas.
• NAVAID Information: Complete details for VOR, NDB, and DME stations, including identifiers and frequencies.

Why Keep Physical ERC Charts?

While Electronic Flight Bags (EFBs) are standard in modern cockpits, physical ERC charts remain a critical asset for serious pilots. They offer an unmatched tactical overview during pre-flight briefings, simplify cross-country routing discussions, and serve as an indispensable, zero-fail backup if your cockpit electronics overheat or lose power.

Regulatory Compliance: Airservices Australia updates ERC charts on a regular AIRAC cycle. Ensure your flight bag is compliant by carrying current editions for your specific flight paths.
