Full title and description

ISO 6858:2017 — Aircraft — Ground support electrical supplies — General requirements. Specifies the electrical output characteristics and the interface requirements between an aircraft and ground support electrical supplies, including central and point-of-use external power generation facilities and associated safety features; excludes region‑specific performance/safety requirements and ground traffic control functions.

Abstract

ISO 6858:2017 defines the performance, interface and safety requirements for ground support electrical supplies used to provide external electrical power to aircraft. The standard addresses nominal outputs for 28 V DC and three‑phase 400 Hz AC (115/200 V or 230/400 V), measurement points at the aircraft attaching connector, protective and safety features, and excludes requirements governed by regional regulations or unrelated ground‑traffic systems.

Scope

This standard applies to the electrical output characteristics and the interface between aircraft and ground support electrical supplies used to supply power to aircraft while on the ground. It covers nominal 28 V DC and three‑phase 400 Hz AC outputs (115/200 V or 230/400 V) measured at the aircraft attaching connector, defines required safety features and interface characteristics, and applies to central and point‑of‑use power generation facilities. It does not address regional regulatory performance/safety requirements or ground‑traffic control equipment such as towing points or identification/warning lights.

Key topics and requirements

• Electrical output characteristics for aircraft external power (nominal voltages and frequency, DC and three‑phase AC).
• Interface requirements and measurement location at the aircraft attaching connector.
• Safety features and protective measures for ground support electrical supplies.
• Compatibility and interconnection requirements for central and point‑of‑use equipment.
• Marking, identification and basic verification/testing provisions for supply equipment.
• Exclusions and limits: regional regulatory matters and ground‑traffic control functions are out of scope.

Typical use and users

Used by aircraft manufacturers, ground support equipment (GSE) designers and manufacturers, airport engineering and maintenance teams, airline technical operations, certification and regulatory bodies, and test laboratories responsible for verifying external power supplies and aircraft power interfaces.
