In China, airfield signs are set by the Civil Aviation Administration of China in MH 5001, the technical standard for airport flight areas — an ICAO Annex 14 aligned standard.
In China, airfield signs are regulated by the Civil Aviation Administration of China (CAAC). The relevant technical standard is MH 5001, Technical Standards for Airport Flight Area (民用机场飞行区技术标准); this page draws on the 2021 edition (MH 5001-2021). This page stays at a scope-and-structure level — what the standard is and how it relates to the international baseline — rather than reproducing dimensions that cannot be verified here.
MH 5001 is anchored to ICAO Annex 14. China is an ICAO member state, and MH 5001 carries the Annex 14 flight-area design provisions — runways, taxiways, markings, lighting and signs — into the national standard, following the ICAO structure closely.
Because MH 5001 follows Annex 14, the sign taxonomy is the familiar one:
The reserved-red rule, the colours and the inscriptions map onto the ICAO baseline; MH 5001 remains the authority for the exact Chinese values and for any national differences.
MH 5001 is China's Annex 14 implementation, comparable in role to CAP 168, TP 312 and the Australian Part 139 MOS — each a national standard built on the same ICAO baseline. The regulations overview sets the authorities side by side.
Wingframe draws airfield guidance signs to ICAO Annex 14 — and EASA and FAA — geometry: the reserved-red rule, the family colours and the legend proportions that MH 5001 builds on. It does not ship a CAAC-specific configuration, so treat it as a correct Annex 14 starting point rather than an MH 5001 compliance check — the exact Chinese values come from MH 5001 itself.
