This AC does not constitute a regulation, is not mandatory and is not legally binding in its own right. This AC will not be relied upon as a separate basis by the FAA for affirmative enforcement action or other administrative penalty. The standards and guidelines contained in this AC are practices the FAA recommends for establishing an acceptable level of safety, performance, and operation for heliports. Conformity with this AC is voluntary, except for the projects described in subparagraphs 1, 2, and 3 below:  \n Use of these standards and guidelines is mandatory for projects funded under Federal grant assistance programs, including but not limited to the Airport Improvement Program (AIP) and Coronavirus Aid, Relief, and Economic Security (CARES) Act Airport Grants program. See Grant Assurance \\#34 . Heliport sponsors should familiarize themselves with the obligations and assurances that apply to each grant program from which they obtained grant funds.  \n This AC is mandatory, as required by regulation, for projects funded by the Passenger Facility Charge (PFC) program. See PFC Assurance \\#9 .  \n This AC has no applicability under Title 14 Code of the Federal Regulations (CFR) Part 139 due to an exemption for heliport operators per §  139.1(c)(5) .  \nOther federal agencies, states, or other authorities having jurisdiction over the construction of heliports not funded with AIP, CARES Act, or PFC funds have discretion in establishing the extent to which these standards apply.  \n4 Related Documents.  \nACs and Orders referenced in the text of this AC do not include a revision letter, as they refer to the latest version. See Appendix E for a list of associated publications.  \n5 Principal Changes.  \nThe AC incorporates the following principal changes:  \n Complete reorganization of this AC:  \na. Consolidated Chapters 2, 3 and 4 (GENERAL AVIATION, TRANSPORT, and HOSPITAL heliport chapters, respectively) into Chapter 2.  \nb. Consolidated Chapter 7 (Heliport Gradients and Pavement Design) into Chapter 2.  \nc. Included a separate Chapter 3 on Heliport Taxiways, Taxi Routes, and Helicopter Parking.  \nd. Included a separate Chapter 4 on Heliport Markings and Lighting.  \ne. Included a separate Chapter 7 on Heliport Site Safety Elements.  \nf. Added new Appendix B, Pre-designated Emergency Landing Areas (PELAs) .  \ng. Incorporated Engineering Brief \\#87, Heliport Perimeter Light for Visual Meteorological Conditions, into this AC to address specific heliport lighting requirements. Heliport lighting design requirements are included in Appendix G.  \n Revised figures and tables to correspond with the design requirements and dimensions for GENERAL AVIATION, TRANSPORT, and HOSPITAL heliports.  \n Enhanced the figures to include dimensional, layout, and offset requirements.  \n Updated the format of the document and made minor editorial changes throughout.  Included a heliport evaluation process flow chart in Appendix F.  \n6 Using this Document.  \nHyperlinks (allowing the reader to access documents located on the internet and to maneuver within this document) are provided throughout this document and are identified with underlined text.
