AACR opinion
Xplorate Group is not a public authority and does not issue permits. Our role is to provide complete technical assistance: we identify the exact coordinates of the site, carry out the topographic survey, prepare the site plan and the description of the works, so that the file submitted to AACR is complete and accurate.
The issuance of the permit and the scheduling process are strictly under the responsibility of AACR, and no consultancy or surveying company has the legal ability to fast-track this process.
AACR is the abbreviation used for the Romanian Civil Aeronautical Authority, and the opinion is a technical documentation that evaluates the degree to which a future construction may be an obstacle for air navigation or may affect flight safety on the territory and in the airspace of Romania.
This opinion is obtained following geodetic measurements executed in the national projection system (stereo 70/Black Sea 1975), but also in the ETRS 89 (WGS-84) ellipsoidal system used in aviation.
The purpose of this aeronautical endorsement is to clarify whether the future infrastructure and construction projects interfere or not with the Civil Aviation flight areas, depending on the opinion issued by AACR, certain restrictions may appear with regard to the location and heights of the future projects to be built.
The opinion issued by the Romanian Civil Aeronautical Authority is an essential component of the urban planning certificate (when the property is located in an area with aeronautical servitude), its absence making it impossible to obtain all the necessary documentation to start the construction works.
It is particularly necessary for the development of urban plans such as P.U.D. (Detailed Urban Plan), P.U.Z.(Regional Urban Plan), P.U.G.(General Urban Plan), D.T.A.C.(Technical Documentation for obtaining the Building Permit) type and confirms that the proposed project does not affect the flight path of aircraft or ground-based radars.
This type of documentation is necessary particularly for buildings in close proximity to airports, even those of low heights, but it can also be requested in case of intention to build an objective at a point that could interfere with certain airspace paths.
In order to obtain the AACR opinion, it is necessary to draw up a technical documentation and carry out some checks by AACR accredited specialists, respectively ROMATSA, in accordance with the provisions of the applicable aeronautical regulations.
FAQ
Is AACR approval required for a regular house?
It may be necessary, even for low-rise buildings, if the site is in an area with aeronautical easements or near aeronautical infrastructures. Check the urban planning certificate, if AACR appears in the list of permits to be obtained, then it is mandatory regardless of the type of construction.
Is the AACR approval the same as the building permit?
No. The AACR approval is an aeronautical technical approval, issued exclusively by the Romanian Civil Aeronautical Authority. The building permit is issued by the competent local authority. The AACR approval is one of the required pieces in the authorization file, when the urban planning certificate requires it.
What documents are required for the AACR file?
Application, urban planning certificate, zoning plan, future construction project, site plan with site coordinates, land elevations, maximum proposed height and description of the works. The technical parts differ depending on the documentation phase: DTAC, PUZ, PUD, SF, DALI or PT.
How much does the AACR approval cost?
The cost varies depending on the location and area of the land, the proposed height of the construction and the complexity of the documentation. After analyzing the project data, we send you a personalized offer.
How long does it take to obtain AACR approval?
Topographical technical documentation is completed within a few business days. The processing time at AACR depends on available appointments, the institution’s workload, and any additions. In 2026, long scheduling deadlines for submitting documentation were reported, according to reports from business organizations. No topography or consulting firm can rush this process.
What happens if the documentation submitted to AACR is incomplete?
AACR requests additions in writing. According to the 2026 amendments, the request for additions is made within a maximum of 30 days from the registration of the technical documentation. Therefore, it is essential that the file is complete and correct from the first submission, each addition adds months of delay.
Do I need AACR approval for panels, antennas or cranes?
It may be necessary, depending on the location, height and possible impact on air navigation safety. Advertising boards, telecommunications antennas, masts and other vertical structures must be assessed if they are located in regulated areas or may constitute obstacles to air navigation. Certainty of the application is provided by the urban planning certificate where AACR approval may not have been requested.
