Why AAI NOC Matters

Securing an AAI NOC before beginning construction near an airport isn’t just a compliance formality. It's a safety requirement that defines the maximum height your structure can achieve. Any mismatch in coordinates, elevation data, or mapping inputs can lead to delays, redesigns, or application rejections.

Additional Support Through AGA & CNS Calculations

Many applicants worry about the height they will actually be allowed to build, particularly because AAI often restricts heights in basic NOCs. To help clients plan better, we also perform AGA and CNS calculations to estimate the permissible height in advance. This gives you a clearer understanding of what to expect before proceeding. If AAI issues a lower height in the basic NOC, these calculations can support you when filing an appeal. In case of any confusion, you can always connect with us for clarity. As a trusted AAI NOC service provider, CAS helps developers and architects obtain accurate AAI building height clearance and avoid costly setbacks. We streamline the entire airport NOC for the construction process for our clients. Our team performs manual AGA (Aeronautical Ground Aids) calculations for basic NOCs. For more than 18 years, we have been managing AAI NOC follow-ups with competence.

Our Process

At CAS, every application is handled with care, consistency, and technical precision. We follow a structured workflow to ensure your submission aligns fully with AAI requirements and the AAI e-NOCAS portal guidelines.

How We Manage Your AAI NOC End-to-End

Checking the Feasibility

In the first place, we collate and verify coordinates, Google elevation data, and survey details. We conduct manual AGA (Aeronautical Ground Aids) & CNS (Communication, Navigation, Surveillance) calculations to determine the permissible height. Our goal is to confirm the structural feasibility of the project.

Support with Documentation

Next, our team works on technical drawings. They prepare the project details and supporting documents required for the NOC application support.
