Aeronautical & OLS Survey UAE
ICAO-compliant aeronautical surveys and obstacle limitation surface (OLS) studies across the UAE. Height clearance analysis, DCAA NOC applications, and runway surveys for airports, towers, and helipads.
Aeronautical Surveys & OLS Studies Across the UAE
Al Warqa Survey Engineering provides aeronautical survey and obstacle limitation surface (OLS) studies across the UAE — covering Dubai, Abu Dhabi, Sharjah, Ras Al Khaimah, and Fujairah. We conduct ICAO-compliant OLS surveys for airports, high-rise towers, construction cranes, helipads, and vertiports, providing height clearance analysis and DCAA NOC application packages.
Every tall building in Dubai and the UAE that falls within a controlled airspace zone requires an aeronautical height clearance study before construction. Al Warqa's aviation survey team delivers the complete service: field survey, OLS modelling, obstacle penetration analysis, and authority submission — with extensive experience across Dubai International Airport, Al Maktoum International, and Abu Dhabi Airport controlled zones.
Our Methodology
Delivering excellence through a proven three-stage workflow
Airspace Zone & OLS Analysis
Confirm airport controlled airspace zone and OLS surface parameters from DCAA and ICAO. Define survey scope and critical obstruction heights.
Precision Survey & Elevation Measurement
Measure existing structure heights, terrain elevations, and proposed development heights using GNSS and total station with verified vertical control.
OLS Modelling & NOC Submission
Model OLS surfaces; analyse height penetrations; prepare DCAA NOC submission package including all required technical documentation.
Applications
Industry sectors and use cases we serve

Frequently Asked Questions
An Obstacle Limitation Surface (OLS) survey identifies buildings and structures that penetrate the imaginary safety surfaces around airports defined by ICAO Annex 14. Any structure within the controlled airspace zone that exceeds these surfaces requires a DCAA No-Objection Certificate (NOC) before construction.
Any development within the controlled airspace zones of Dubai International Airport (DXB) or Al Maktoum International (DWC) that exceeds a certain height threshold requires a DCAA height clearance study. Al Warqa can quickly determine if your project is affected.
DCAA typically processes NOC applications in 4–8 weeks. Al Warqa prepares technically complete submissions to avoid rejection and can provide preliminary height assessments quickly to support planning decisions.
Yes. We provide aeronautical surveys and height clearance studies for all UAE airports including Abu Dhabi International (AUH), Sharjah International (SHJ), Ras Al Khaimah (RKT), and Fujairah (FJR).
