On February 15, 2015, the Federal Aviation Administration published its highly anticipated Notice of Proposed Rulemaking (NPRM) on the Operation and Certification of Small Unmanned Aircraft Systems (applicable to UAS weighing 55 lbs. and less).  The proposed rules would add a new Part 107 to Title 14 Code of Federal Regulations to allow for routine civil operation of small UAS in the National Airspace System (NAS).  Although a lengthy comment and revision period is expected to delay finalization of the regulations for another 18-24 months, Section 333 of the FAA Modernization and Reform Act of 2012 will continue to provide a procedure for expedited authorization of commercial small UAS operations in the interim.  The final Part 107 will serve as the foundation for a multi-billion dollar UAS industry in the United States.

The Federal Aviation Administration (“FAA”) has added another arrow to its quiver in its ongoing campaign to limit residential and commercial development in even the remotest vicinity of airports.  In late April, FAA originally published a “Proposal to Consider the Impact of One Engine Inoperative Procedures in Obstruction Evaluation Aeronautical Studies” (“Proposal”) which seeks to supplement existing procedures for analyzing the obstruction impact of new structures or modifications to existing structures on aircraft operations within certain distances around airports (see 14 C.F.R. Part 77), with consideration of the impact of structures on one engine inoperative (“OEI”) emergency procedures.  OEI procedures are not currently included in FAA’s obstruction regulations which advise local land use jurisdictions on appropriate limits to building heights within specified geographic zones around airports to accommodate the takeoff and landing clearance needed by aircraft with their full complement of operating engines.  From an aeronautical perspective, FAA’s initiative sounds desirable and long overdue, even though the occurrence of engine loss is rare.  From the perspective of local jurisdictions, landowners and developers, however, the proposal is anathema, potentially leading to dramatically lower allowable building heights and concomitantly reduced property values, even far from the airport.
