In a marked change in longtime Federal Aviation Administration (“FAA”) policy regarding analysis of noise and air quality impacts from FAA initiated, directed or funded projects, FAA has substituted a single new model for the long mandated Integrated Noise Model (“INM”) and Emissions and Dispersion Modeling System (“EDMS”).  Beginning May 29, 2015, FAA policy “requires” the use of the Aviation Environmental Design Tool version 2b (“AEDT 2b”), which integrates analysis of aircraft noise, air pollutant emissions, and fuel burn.  These impacts, according to FAA are “interdependent and occur simultaneously throughout all phases of flight.”  80 Fed.Reg. 27853.  

 
The FAA policy provides for differential displacement of existing analytic models.  For air traffic and airspace procedural changes, AEDT 2b replaces AEDT 2a, already in use.  For other, ground based projects, AEDT 2b replaces both the INM, for analyzing aircraft noise, and EDMS for developing emissions inventories and modeling emissions dispersion.  The change was presaged by FAA Administrator Michael Huerta who announced in April that FAA was undertaking an “ambitious project” to revamp its approach to measuring noise.  The “ambitious project” was apparently inspired by the vocal objections to the results of the analysis using current methodologies, voiced by citizens of locals that have experienced the effects of FAA’s current, nationwide reorganization of airspace around major airports to institute procedures based on Performance Based Navigation (“PBN”).

On June 25, 2014, the Federal Aviation Administration (“FAA”) published in the Federal Register, 79 Fed.Reg. 36172, its “Interpretation of the Special Rule for Model Aircraft” (“Interpretation”) established by Congress in the FAA Modernization and Reform Act of 2012, Pub.L. 112-95, § 336 (“FMRA”).  Despite its name, FAA’s interpretation goes far beyond mere definitional clarification.  It is, instead, the first step in establishing FAA’s preemptive authority over Unmanned Aircraft Systems (“UAS”) as “aircraft” utilizing the National Airspace System (“NAS”), even where the operator of an UAS chooses to denominate it a “model aircraft.” 

As a first step in asserting its regulatory authority, FAA takes the position that Congress’ rule in the FMRA is nothing new, but, instead, relies heavily on the long standing statutory and regulatory definition of model aircraft as “aircraft,” i.e., mechanisms that are “invented, used or designed to navigate or fly in the air,” 49 U.S.C. § 40102; 14 C.F.R. § 1.1.  FAA also applies its own 2007 guidelines regarding UAS operating in the NAS, which recognizes that UAS fall within the statutory and regulatory definition of “aircraft” as “devices that are used or intended to be used for flight in the air with no onboard pilot.”  72 Fed.Reg. 6689 (February 13, 2007). 

FAA’s Interpretation, however, goes far beyond the simple inclusion of “model aircraft” in the category of “aircraft.”  The Interpretation expands even further upon FMRA’s three part test defining a “model aircraft” as an “unmanned aircraft” that is: “(1) capable of sustained flight in the atmosphere; (2) flown within the visual line of sight of the person operating the aircraft; and (3) flown for hobby or recreational purposes.”  FMRA, § 336(d). 
 
With regard to FMRA’s second factor, the requirement that the model aircraft stay within the “visual line of sight” of the user, FAA interprets that requirement consistent with FMRA, § 336(c)(2) to mean that: (1) the aircraft must be visible at all times to the operator; (2) that the operator must use his or her own natural vision (including corrective lenses) and not goggles or other vision enhancing devices; and (3) people other than the operator may not be used to maintain the line of sight.  In other words, to maintain the identity as a “model aircraft,” the aircraft cannot be “remotely controlled” from a location other than that at which it is being flown.

The third factor, the definition of what constitutes “hobby or recreational use” is perhaps the thornier.

While many members of the growing community of developers, manufacturers and operators of Unmanned Aircraft Systems (“UAS”) have expressed enthusiasm at the National Transportation Safety Board Administrative Decision in the Pirker case, Administrator v. Pirker, NTSB Docket CP-217, July 18, 2013, their reaction should be tempered by the law of unintended consequences.  The outcome of the administrative action, which the Federal Aviation Administration (“FAA”) has since appealed, acknowledges not only the FAA regulation that is certain to arise as a result of the Congressional mandate contained in the FAA Modernization and Reform Act of 2012, Pub. L. 112-95, § 334 (“FMRA”), but also opens the door to unrestricted local regulation. 

Specifically, Pirker’s argument is based on the assumption that the UAS at issue is a “five-pound radio-controlled model airplane constructed of styrofoam [sic],” Motion to Dismiss, p. 1.  He does not cite, or even refer to, any operant statutory or regulatory definition of “model aircraft.”  On that basis, Pirker alleges that his operation of the “model airplane” cannot be regulated because FAA has “fallen far behind its own schedule, as well the scheduled mandated by Congress,” Motion to Dismiss, p. 1, for enacting regulations.  Pirker again fails to refer the Court to the full extent of the Congressional mandate in FMRA which effectively disposes of his fundamental argument.
