NPAIS Airport Obstruction Surveys

NPAIS Airport Obstruction SurveysKMA was retained by AECOM, USA to perform ground surveying services associated with aeronautical obstruction surveys at various National Plan of Integrated Airport Systems (NPAIS) airports in New Jersey. Surveying and analysis were performed for the following airports:

  • Monmouth Executive Airport (Type 3 Airport)
  • Greenwood Lake Airport (Type 4 Airport)
  • Central Jersey Airport (Type 4 Airport)
  • Sussex Airport (Type 4 Airport)

Ground surveying tasks were performed pursuant to Federal Aviation Administration (FAA) Advisory Circulars (ACs) AC 150/5300-16A, AC 150/5300-17G, and AC 150/5300-18B. Work included coordination, field work and office analysis, and reporting. KMA coordinated its efforts with AECOM, AECOM’s mapping consultant, the NJDOT Aeronautics Division, and the appropriate airport managers. Field work and office analysis included survey control, performing vertical profiles of runways, and supplemental survey.

For the survey control, KMA processed ABGPS data using CORS stations and referenced the data to the NAD83/2011 in the NJ State Plane Coordinate System (horizontal), and NAVD88 (vertical). Runway profile surveys consisted of three parallel profiles, with survey shots at 50 foot intervals. Supplemental survey consisted of position, elevation, and navigational aid perpendicular point of electronic and visual navigational aids (NAVAIDS), obstruction obstacles or planimetric features not collected by photogrammetric mapping methods, and other features not collected by photogrammetric mapping methods (i.e., valves, etc.).

A survey control report was prepared for each airport and submitted through FAA’s airports Geographic Information System (AGIS) database.
