Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

The location of the T-hangars was constrained by the Riparian Corridor of Middle Ditch, wetlands, and Part 77 surfaces. The proposed location of the hangars was the only place that met those constraints. Restrictions Taxiway and hangars should only be used by aircraft with a maximum wingspan of 42 ft. Justification Hangars location within the Passaic River Basin and constrained by the Riparian Corridor of Middle Ditch, wetlands, and Part 77 surfaces. Satisfactory OFA clearance when aircraft with wingspan up to 42 ft long travels on the taxilane based on the modified equation found in AC 150/5300-13, Chapter 4, at the bottom of Table 4-1 (1.2 × wingspan + 20 ft).

TRB’s Airport Cooperative Research Program (ACRP) Report 51: Risk Assessment Method to Support Modification of Airfield Separation Standards is intended to be used to support requests for modification of standards in those circumstances where the design criteria for separations between taxiways/taxilanes and other taxiways/taxilanes and fixed or movable objects as well as separations between taxiways and runways cannot be met.

The following appendices, included in the pdf and print version of the report, will be helpful in understanding the methodology.

  • Appendix A: Risk Assessment Methodology presents a methodology for five different types of circumstances: taxiway/taxilane to taxiway, taxiway to object, taxilane to taxilane, taxilane to an object, and runway to taxiway/taxilane or object;
  • Appendix F: Aircraft Database Summary presents a summary of aircraft characteristics by model; and
  • Appendix H: Analysis of MOS Cases summarizes information collected in the modification of standards survey and presents results of application of the methodology described in Appendix A to each modification of standards case.

Other report appendices, which are available online only, provide detail and information on the development of the methodology.

In addition, the project developed a

PowerPoint presentation

that may be useful for introducing and explaining the methodology to stakeholders.

In July 2021, an errata was posted for this publication: In Table 7 on page 25, the LDVO coefficient was changed from -3.088 to -13.088. The online version of the report has been corrected.
