The aerodrome or proposed structure is checked against the Annex 14 obstacle limitation surfaces, the protected zones extending out from the runway. Any penetration or risk is named specifically, not flagged as a general concern.

How We Assess Your Aerodrome's Annex 14 Compliance
ANNEX 14 Analysis & reporting
An Annex 14 Analysis applies whether you operate the aerodrome or you're building near one. We map the Annex 14 obstacle limitation surfaces around the runway, then check whether the aerodrome itself, or a structure proposed nearby, such as a turbine, mast, building, or powerline, sits inside them. We also check the communication, navigation, and surveillance infrastructure, along with air traffic management and airspace, so the analysis covers more than physical clearance. You get a report that names any penetration or risk in plain terms and sets out what to change to fix it.

Here's how the process works and what you will get
01
An aerodrome is being planned, upgraded, or certified
02
An aerodrome is due for a compliance audit or safeguarding review
03
A runway is being extended or its operations are changing
04
Wind turbines, masts, a solar facility, buildings, or powerlines
SOMETHING TO NOTE
We structure every Annex 14 report to go straight into a planning submission or regulatory approval process, findings and fixes included, so nothing needs to be reworked before it can be used.

What a Complete Annex 14 Analysis Actually Covers
CHECK 01 — AIRSPACE & SURFACES
Annex 14 Obstacle Limitation Surfaces
What you get:
A written breakdown of exactly where the protected airspace is affected, and by how much.
CHECK 02 — SYSTEMS & AIRSPACE
The Aviation Airspace Concept
The analysis also checks against the wider Aviation Airspace Concept, covering communication, navigation, and surveillance infrastructure, plus air traffic management and the route network structure.
What you get:
Clear mitigation where there's a risk, a height limit, repositioning, marking, lighting, or an operational restriction, built to go straight into a planning submission or regulatory approval process.
