To successfully register and commission a helipad in Brazil, property owners and project developers must navigate two complementary regulatory tracks: obtaining airspace clearance from the Aeronautical Command (COMAER) through DECEA (Brazil's Department of Airspace Control), and securing infrastructure registration or certification with ANAC (Brazil's National Civil Aviation Agency). Regular landing and takeoff operations are legally permitted only after the formal authorization is published in the DOU (Diário Oficial da União, Brazil's Official Gazette).
Rapid urban verticalization and growing helicopter traffic have prompted aviation authorities to conduct increasingly rigorous reviews. Healthcare facilities, corporate headquarters, luxury residential towers, and industrial plants must align their civil engineering plans with aviation operational safety standards from the initial architectural stages. Remediating a helipad after construction is completed is substantially more expensive than designing it with aeronautical regulatory criteria from day one.
What is required to register a helipad in Brazil?
Regulatory registration requires demonstrating that the site does not pose a hazard to air navigation and that the physical facility complies with safety parameters established by Brazilian aviation authorities. This compliance is evaluated from two institutional viewpoints:
- DECEA / COMAER: assesses the impact of the infrastructure and its approach and departure corridors on local air traffic patterns and neighboring aerodromes.
- ANAC: inspects the civil engineering and facility design, including landing area dimensions, dynamic load-bearing capacity, visual markings, aeronautical lighting systems, and firefighting infrastructure, under the technical standards of RBAC No. 155 (Brazilian Civil Aviation Regulation for helipads).
Furthermore, the civil project must adhere to vertical clearance limits and surrounding obstacle constraints, which correlate with an Airspace obstacle analysis (OPEA) whenever new structures are built within its operational influence zone.
Preliminary feasibility study and site selection
Before initiating construction on a building rooftop or at ground level, conducting a preliminary aeronautical technical feasibility study is essential. The objective is to verify whether the surrounding geographical and urban environment can safely accommodate the obstacle clearance slopes required for the intended helicopter models.
During this stage, developers establish the design helicopter (helicóptero de projeto), which represents the largest and heaviest aircraft anticipated to use the facility in terms of maximum takeoff weight, overall length, and rotor diameter. The physical footprint of the deck and its surrounding obstacle limitation surfaces derive directly from this selection. A frequent mistake is sizing a platform for an existing aircraft during the design phase, only to discover later that larger operational helicopters cannot land safely.
Another critical step is mapping surrounding obstacles, such as adjacent high-rises, communication towers, power lines, and lampposts. Early technical screening prevents a project from becoming unviable due to nearby vertical structures that cannot be removed or lowered.
Design requirements and aeronautical topographic surveys
The executive engineering project must translate the regulatory provisions of RBAC No. 155 into field execution. This involves correctly dimensioning three core elements: the touchdown and lift-off area (TLOF), the final approach and takeoff area (FATO), and the surrounding safety area. Each serves a distinct operational purpose, with minimum dimensions determined by the design helicopter and planned operating conditions.
For coordinates and elevations to be accepted by DECEA and ANAC, project developers must perform Aeronautical topographic surveys tied to the SIRGAS 2000 geodetic reference frame (Geocentric Reference System for the Americas). This geodetic survey defines the helipad reference point coordinates, elevation above mean sea level, and precise locations of all surrounding obstacles. This accurate baseline underpins the PBZPAH and eliminates formal requests for corrections due to field-to-drawing discrepancies.
| Technical parameter | Elevated helipad (rooftop) | Surface-level helipad |
|---|---|---|
| Supporting structure | Requires dynamic impact load structural calculations for the slab | Subgrade pavement dimensioned for localized axle loads |
| Fire protection | Fixed fire suppression system and dedicated emergency exits | Portable extinguishers or wheeled fire carts based on category |
| Surrounding zoning | Lower vulnerability to ground clutter, but higher wind exposure | Higher risk of interference from nearby vegetation and buildings |
| Accessibility | Requires dedicated evacuation stairs, ramps, or service elevators | Direct access via internal facility roads and pathways |
The role of the PBZPAH in DECEA airspace clearance
The Basic Helipad Protection Zone Plan (PBZPAH) is the cartographic and descriptive dossier defining the obstacle limitation surfaces surrounding the facility. The technical development of Protection Zone Plans (PBZPA & PBZPAH) adheres to DECEA standards and must reflect real-world conditions rather than theoretical models.
The regulatory filing is submitted to the regional CINDACTA (Integrated Air Defense and Air Traffic Control Center) responsible for the airspace where the helipad is located. CINDACTA assesses whether the proposed facility interferes with controlled airspace, published helicopter routes (REH - Rotas Especiais de Helicópteros), or third-party flight safety.
Upon a favorable review from COMAER, the authority issues a formal clearance document approving the helipad implementation and its associated approach corridors. Without this positive DECEA determination, ANAC will not process the infrastructure registration.
ANAC registration through Official Gazette publication
Once DECEA clearance is granted and physical construction is complete, the project proceeds to formal filing for Helipad & airfield registration with ANAC. The application is submitted alongside comprehensive supporting documentation.
Essential filing documents include:
- Standardized application forms executed by the facility owner or designated operator;
- Airspace clearance authorization issued by COMAER/DECEA;
- Technical Responsibility Notes (ART) or Technical Responsibility Records (RRT) from certified engineers for civil, structural, electrical, and topographic disciplines;
- Proof of legal property ownership or authorized land/building use agreement;
- Helipad Emergency Plan and photographic evidence of installed day markings and nighttime visual lighting aids.
ANAC technical teams audit regulatory compliance and verify the consistency of the submitted data. When all engineering and legal standards are met, ANAC issues the registration or certification decision, which is published in the DOU (Diário Oficial da União). Following gazette publication, the facility is incorporated into Brazilian aeronautical information publications and officially declared open to air traffic.
Norte Sul Consult works with an average benchmark of 60 to 120 days from the initial administrative filing to publication in the DOU, depending on specific project complexities and agency review backlogs. Incomplete technical documentation and post-filing design alterations are the primary contributors to schedule overruns.
Common errors that delay helipad registration
Field experience indicates that the majority of application delays and rejections stem from documentary deficiencies and inconsistencies between architectural designs and aviation standards. The most frequent errors include:
- Geodetic coordinate discrepancies: differences between architectural floor plans and certified SIRGAS 2000 geodetic coordinates trigger immediate formal objections from DECEA.
- Omission of surrounding obstacles in the PBZPAH: failing to identify trees, antennas, or utility poles that penetrate approach surfaces halts technical evaluations at CINDACTA.
- Inverted filing sequence: submitting an application to ANAC before securing prior airspace approval from DECEA leads to immediate procedural return of the dossier.
- Non-compliant markings and visual aids: installing light fixtures, visual indicators, or surface markings that do not conform to regulated chromatic, intensity, and photometric specifications.
- Absence of qualified engineering certifications: submitting drawings and technical reports without the required professional registration notes (ART/RRT) for civil engineering, surveying, and aviation design.
Mitigating these potential issues early in the engineering phase is significantly more cost-effective than revising submitted dossiers. A helipad does not function in isolation: it integrates with surrounding urban terrain and active airspace, highlighting the necessity of an early technical diagnosis.
