Runway 3-21 Realignment /Safety Area Improvements

Orange County Airport, NY

New York’s Orange County Airport (FAA LID: MGJ) is located one nautical mile (2 km) southwest of the village of Montgomery, in the Town of Montgomery, United States.

The intent of this project was to improve the Runway Safety Area (RSA) to comply with current FAA standards as contained in AC 150/5300-13 by realigning the runway 3-21. The existing Runway 3-21 and parallel Taxiway A will be removed and 5006 feet by 100 feet Runway 4-22 and 5000 feet by 35 feet Taxiway A will be installed. The major design elements of this project were Runway and Taxiway pavement, associated Airfield lighting system, relocation of navigational system, and drainage improvement. DY Consultants was the electrical engineer for this major effort, which involved the redesign of the airfield’s visual and navigational aids.

The electrical design included:

  • Removal of the existing Runway and Taxiway Edge lights and Signage
  • Installation of Runway and Taxiway Edge Lights
  • Removal of existing VASI and relocation of existing PAPI
  • Installation of New FAA owned PAPI
  • Installation of new REILs
  • Relocation of Localizer Antennas and Shelter
  • Relocation of Glide Path antenna tower and shelter
  • Relocation of Segmented Circle and Wind Cone

These facilities were designed to service the relocated Runway 2-22 and its parallel Taxiway A.  Design effort for FAA-owned equipment such as the ILS and new 4 lights Unit PAPI were coordinated with the FAA.  The cable layout for the airfield modified substantially, such that the high voltage wiring system and its electrical components will require new homeruns, along with modifications to the vault room. Adjustments within the electrical vault upgraded Constant Current Regulators (CCR’s) and other equipment will meet current standards and electrical codes.
