At COMPLYN ADVISORY SERVICES, we deliver structured, documentation-based solutions for regulatory clearances and project coordination.
Our role is to simplify the approval journey through organized documentation, predictable communication, and professional follow-through across sectors in India and the UK.
We guide clients through the complete AAI Basic NOCs process by preparing accurate documents, reviewing project details, and coordinating with aviation authorities. For basic NOCs, we perform AGA (Aeronautical Ground Aids) calculations. Each case is handled with steady communication and careful documentation management. The senor NOC advisors in our team bring up to 33 years of experience to the table.
Appeals often arise when a Basic NOC is restricted or when the permissible height is lower than expected.We have been managing AAI NOC Follow-ups for more than 18 years, handing the appeal from start to finish, including manual AGA (Aeronautical Ground Aids) & CNS (Communication, Navigation, Surveillance) calculations. Our competent professionals handle everything from preparing the technical and supporting documents, drafting architect justification letters, and coordinating on the AAI NOC appeal until the case reaches closure. Our proficient team has managed over 7500+ cases successfully till date.
The approach we take is methodical and organized.
Starting with a comprehensive case review to analyse the specifications of rejection or acceptance, we conduct AGA (Aeronautical Ground Aids) & CNS (Communication, Navigation, Surveillance) calculations and prepare technical documentation such as layout plans, aeronautical data, site survey letters and justification notes from architects for appeal cases. These documents form the foundation of most approval processes. Each one is prepared with precise attention to accuracy and formatting requirements. We then compare them to find possible discrepancies with the evaluation of the AAI. From preparing the appeal to filing and following up, our team offers a comprehensive support. We also support our clients throughout the reporting and closure processes.
Many projects face delays due to incomplete documentation or unclear communication. And that is where CAS comes to the rescue. We support real estate, infrastructure, IT, and manufacturing teams by preparing required documents, reviewing project needs, and directly coordinating with authorities to ensure accuracy, consistency, and disciplined adherence to compliance procedures.
We prepare, review, and organize all essential documents, manage submissions, and coordinate with authorities on behalf of clients. This keeps the approval workflow structured and reduces the risk of procedural errors.
We support teams across a broad range of sectors.
Our processes adapt to industry-specific documentation standards and the requirements established by concerned authorities. The industries we serve include, but are not limited to:
