Obstruction Evaluation/Airport Airspace Analysis (OE/AAA)


Federal Regulation Title 14 Part 77 establishes standards and notification requirements for objects affecting navigable airspace. This notification serves as the basis for:

  • Evaluating the effect of the construction or alteration on operating procedures
  • Determining the potential hazardous effect of the proposed construction on air navigation
  • Identifying mitigating measures to enhance safe air navigation
  • Charting of new objects

Notification allows the FAA to identify potential aeronautical hazards in advance to prevent or minimize the adverse impacts to the safe and efficient use of navigable airspace.
