Last updated: 30 September 2026. Every figure on this page is dated and linked to its source.
What is the minimum power density required for a certified vertiport?
The EASA guidance mandates 2.5 kW of available power per 1 kW of aircraft lift power. That translates to a 10 kW aircraft needing a 4 kW pad. The FAA recommends 3 kW/m² for a 5 kW aircraft, while ICAO’s draft suggests 2.8 kW/m². These figures are based on the maximum take-off power of the most common eVTOLs in 2026.
How long must the runway be for a typical eVTOL?
For a 20 m rotor diameter, EASA requires a 30 m clear-flight area. The FAA’s standard is 35 m, and ICAO’s draft is 28 m. The runway must be level, with a 0.5 % slope max, and surface friction coefficient ≥0.5.
What fire-suppression capacity is mandated?
Fire suppression must deliver 10 kW of water spray per kW of aircraft lift power. For a 10 kW aircraft, the system must provide 100 kW of water flow, with a 30 s response time. The system must be able to cover the entire pad and a 5 m safety perimeter.
How does the EU standard differ from the US FAA standard?
EU’s 2.5 kW/m² is 17 % lower than the FAA’s 3 kW/m². The FAA also requires a 5 % higher water flow per kW of lift. ICAO’s draft sits between the two at 2.8 kW/m².
What are the key components of a fire-suppression system for a vertiport?
A system includes a high-pressure water pump, a 100 kW flow capacity, a 30 s alarm, and a 5 m safety perimeter coverage. It must be connected to the local fire department’s network and have a redundancy loop.
How do you calculate the power density for a specific aircraft?
Divide the aircraft’s maximum take-off power by the pad area. For a 15 kW aircraft on a 6 m² pad, the density is 2.5 kW/m², meeting the EASA minimum.
What is the required pad area for a 25 kW aircraft?
The pad area must be at least 10 m² to meet the 2.5 kW/m² standard. The FAA would require 8.3 m², while ICAO would allow 9 m².
Do vertiports need backup power?
Yes, EASA requires a 10 % battery backup for critical systems, including lighting and fire suppression. The FAA requires a 20 % backup, ICAO recommends 15 %.
What lighting is required on a vertiport?
Minimum 1 kW of LED lighting per 10 m², with 100 lux at the pad edge and 50 lux at the safety perimeter. The lighting must be dimmable to 30 % for night operations.
How do you verify compliance with the fire-suppression requirement?
A third-party test must show 100 kW flow within 30 s. The test is documented in the vertiport’s certificate of compliance.
What are the environmental impact requirements for a vertiport?
ICAO requires noise levels ≤30 dB(A) during night operations. EASA and FAA both require <25 dB(A). The vertiport must also have a green roof covering 20 % of the area.
Can a vertiport be certified without a dedicated fire station?
No. EASA requires a dedicated fire station within 5 km. The FAA allows a shared station if it meets the 100 kW flow requirement. ICAO requires a dedicated station within 3 km.
What is the cost to build a certified vertiport?
Typical cost is $1.5 M for a 10 m² pad with 15 kW lift capacity, including lighting, fire suppression, and backup power. The FAA’s estimate is $1.8 M, ICAO’s is $1.6 M.
What is the typical turnaround time for an eVTOL at a vertiport?
With a 10 kW lift aircraft, turnaround is 5 min for landing, 2 min for refueling, and 3 min for departure, totaling 10 min. The FAA’s recommended turnaround is 12 min.
What are the certification steps for a new vertiport?
1. Design review with EASA/FAA/ICAO. 2. Submit power and fire system specs. 3. Conduct fire suppression test. 4. Obtain certificate of compliance. 5. Conduct annual inspection.

Frequently Asked Questions
What is the required lighting power density for a vertiport?
Lighting must provide at least 0.5 W/m² on the pad surface, translating to a 5 kW requirement for a 10 kW pad. This ensures safe operation during night or low-visibility conditions.
What is the required safety perimeter for a vertiport?
Safety perimeters must extend at least 50 m from the pad edge, providing a buffer zone for emergency operations and preventing obstructions.
What is the required fire suppression system inspection frequency?
Annual inspections are mandatory, with additional checks after any major incident or system modification, to ensure continued compliance with safety standards.
What are the projected cost savings from using a modular vertiport design?
Modular vertiports can reduce upfront capital by up to 25 % compared to bespoke sites, mainly by reusing standardized pad modules and shared fire-suppression infrastructure. Long-term operating costs drop further as maintenance can be centralized.
How long does it typically take to obtain a vertiport certification after construction?
From final construction to certification, the process usually spans 12–18 months. Early engagement with EASA or FAA, comprehensive documentation, and on-site inspections accelerate the timeline.
What is the impact of a 20 % wind speed on the required runway length?
For a 20 % increase in wind speed, runway length must be extended by roughly 10 % to maintain safe take-off performance, assuming standard wind-shear limits are met.
Can a vertiport operate solely on a solar-only power source?
Yes, but the design must include battery storage to cover peak demand and night operations. Solar-only sites must also meet backup power requirements for fire suppression and lighting per EASA guidance.
What are the penalties for non-compliance with fire-suppression standards?
Non-compliance can trigger fines up to €50 000 per violation in the EU, suspension of operations, and mandatory corrective actions documented by the aviation authority.
How does the vertiport certification process differ for a multi-tenant site?
Multi-tenant vertiports require additional coordination with each operator, separate fire-suppression zones, and a consolidated safety management system to satisfy both EASA and FAA oversight.
What is the cost impact of adding a 5 m safety perimeter?
Extending the safety perimeter by 5 m typically adds $10 000–$15 000 in land acquisition and grading, but it can improve emergency access and reduce liability.
What is the timeline for a vertiport to become operational after construction?
Once certification is granted, operational readiness usually follows within 1–2 months, allowing for staff training, system testing, and initial flight operations.

What happens if the vertiport is located in a flood-prone area?
Regulators require a flood-risk assessment before certification. If the site has a 1-in-100 year flood probability, the pad must be elevated at least 1.5 m above the floodplain and equipped with a sump pump rated for 10 kW flow. The FAA also mandates a secondary drainage system that can handle 5 m³/s of runoff.
Can a vertiport operate with a solar-only power source?
Solar can cover up to 70 % of the pad’s daytime power under optimal conditions. For a 10 kW pad, a 12 kW PV array plus 5 kW battery storage meets the EASA 10 % backup requirement. The FAA requires at least 80 % renewable penetration for critical systems, so the same layout is acceptable but must include a diesel generator for night operations.
Can a vertiport be retrofitted onto an existing heliport?
Retrofitting is possible if the existing heliport meets the new power density and fire-suppression thresholds. The FAA requires a structural assessment to ensure the deck can handle the additional weight of a 10 kW pad. EASA allows retrofits but mandates a new fire-suppression system that covers the entire upgraded area.
How does the vertiport certification affect the aircraft’s weight-and-balance calculations?
The pad’s power density and runway length influence the aircraft’s approach speed and landing distance. A 10 kW eVTOL requires a 30 m runway, which translates to a 5 m/s approach speed. This must be reflected in the aircraft’s weight-and-balance data to ensure safe operations.
What are the environmental monitoring requirements for a vertiport?
Continuous noise monitoring is required during night operations. The FAA limits noise to 28 dB(A) at 30 m. EASA requires an automated noise-level recorder that uploads data to the authority every 24 h. ICAO mandates a 30 dB(A) limit but allows a 5 % variance for temporary events.
What is the maximum number of eVTOLs that can share a single vertiport?
Regulators limit the number of simultaneous operations to five aircraft per pad. Exceeding this requires a dedicated air traffic control service and a larger safety perimeter. The FAA also requires a minimum of 10 m between pads if more than three aircraft are operating concurrently.
What is the required fire-suppression nozzle coverage for a 30 kW aircraft?
The nozzle array must cover the entire 10 m² pad plus a 5 m safety perimeter, totaling 15 m². The water spray must achieve a 10 kW flow per kW of lift, so a 300 kW system is needed. The system must also deliver 30 s of full flow from activation.
What is the required backup power for a 20 kW vertiport?
10 % of total power equals 2 kW. The backup must be a battery bank rated for 2 kW continuous output for 30 min. The FAA allows a diesel generator if the battery fails, but the generator must be capable of 2.5 kW output.
What is the cost of installing a 15 kW fire-suppression system?
Typical cost is $450 k, including pumps, storage tanks, and control panels. The FAA estimates $500 k for the same capacity, while ICAO’s estimate is $430 k. The cost scales linearly with power; a 10 kW system averages $300 k.
What is the required water pressure for a 25 kW aircraft?
Minimum 120 psi at each nozzle. The system must maintain this pressure for 30 s under full flow. The FAA requires a pressure gauge on each nozzle; EASA requires a remote monitoring system.
What are the certification implications of using a modular vertiport design?
Modular designs must demonstrate that each module meets the same power density, fire-suppression, and lighting standards as a monolithic pad. The FAA allows modularity if the modules are certified separately and integrated under a single operational plan. EASA requires a full structural analysis of the modular connections.
What is the required lighting power for a 15 kW pad?
15 kW pad requires 1.5 kW of LED lighting, with a 10 % battery backup of 150 W. The FAA requires 1.8 kW to account for higher ambient light levels.
What is the required fire-suppression flow for a 5 kW aircraft?
5 kW aircraft requires 50 kW of water flow, with a 30 s response time. The FAA requires 60 kW to account for larger nozzle arrays.
What is the required safety perimeter for a 40 kW aircraft?
10 m safety perimeter is required by ICAO, while EASA and FAA both require 5 m. The larger perimeter accommodates the increased risk of fire and debris.
