Before TJOFLAT, MARTIN, and JILL PRYOR, Circuit Judges.

PER CURIAM:

      Guy St. Amour appeals his conviction for operating an aircraft with an

unapproved fuel system in violation of 49 U.S.C. § 46306(b)(9). He argues that

the term “operates an aircraft” covers actions during or imminent to flight.

Therefore, he contends, the term does not reach his taxiing and refueling of an

aircraft in preparation for a flight on the following day. We disagree. As defined

in both the United States Code and the Code of Federal Regulations—and clarified

through the decisions of the Civil Aeronautics Board (“CAB”) and the National

Transportation Safety Board (“NTSB”)—the term “operate” encompasses the

refueling of an aircraft for the purpose of flight.

                                           I.

                                           A.

      St. Amour became licensed as a pilot in 1999 and since then has

occasionally worked as a “ferry pilot,” which means that he facilitates the sale of

aircraft by flying them to the locations of purchasers. Javier and Rolando Peyrat,

two Paraguayans, retained St. Amour’s services as a ferry pilot sometime in late

2012 or early 2013. They hired him to fly a Cessna 182 single-engine aircraft,

registration number N3482F, from the Ft. Lauderdale Executive Airport (“FXE”)




                                            2

in Florida to Asunción, Paraguay—a city in the heart of South America. 1 In

preparation for this journey of nearly 4,000 miles, St. Amour sought to outfit

N3482F with an auxiliary fuel system of his own design.

       The auxiliary fuel system consisted of a plastic, maritime fuel tank secured

with a ratchet strap to the back seat of the aircraft. From the plastic tank ran a clear

hose that exited the aircraft through a fitting in the fuselage. The hose ran up the

wing and into the fuel tank of the aircraft. It was secured to the wing with duct

tape. Inside the cabin, an electric pump pushed fuel from the plastic tank, through

the hose, and into the aircraft’s fuel tank. The pump was powered by a cigarette

lighter in the cockpit.

       St. Amour hired a mechanic at FXE named Raphael Garzon to install this

auxiliary fuel system. Garzon, however, failed to complete the installation because

he could not install a modified fuel cap in one of the wings, which prevented the

fuel line from the plastic tank from being fed into the aircraft’s tank. St. Amour

thus hired another mechanic named Patricio Farias to finish the job.

       On March 27, 2013, St. Amour taxied N3482F to Farias’ hangar at FXE.

Farias completed the installation of the fuel system in a few hours for $100. With

the installation complete, St. Amour started the aircraft’s engine and taxied to a

maintenance facility for refueling. Later that day, agents of the Drug Enforcement

       1
         We presume that St. Amour intended to break this trip into a number of legs, since the
single-engine Cessna, even modified, does not have a range of 4,000 miles.

Agency (“DEA”) apprehended St. Amour in front of the maintenance facility on

suspicion of drug trafficking. 2

       During an interview with DEA agents, St. Amour said that he had planned to

depart in N3482F for Paraguay between 10 a.m. and 11 a.m. the following day,

March 28. 3 While the DEA agents neither discovered drugs nor arrested St.

Amour, the situation was referred to the Department of Transportation (“DOT”).

Much later, in an interview with DOT agents, St. Amour again stated that he had

planned to leave for Paraguay the following day and would have but for the

intervention of the DEA.

                                                B.

       On January 6, 2017, a one-count indictment was filed against St. Amour for

operating an aircraft with knowledge that the auxiliary fuel system did not comply

       2
         The DEA received a tip from a confidential source that a suspicious aircraft was parked
outside the maintenance facility and about to depart.
       3
           The transcript of the conversation between St. Amour and the DEA agents reads as
follows:
       SA PETRASEK             Yeah, when is the aircraft scheduled to leave?
       ST. AMOUR               I’m supposed to leave tomorrow.
       SA PETRASEK             Tomorrow?
       ST. AMOUR               Yeah.
       SA PETRASEK             What time tomorrow?
       ST. AMOUR               Uh, tomorrow between ten, eleven.
       SA PETRASEK             Ten, eleven?
       ST. AMOUR               Yeah.
       SA KEENAN               Is it flight ready, operational now?
       SA PETRASEK             Is it flight ready and operational now?
       ST. AMOUR               Flight ready?
       SA PETRASEK             Yeah. Is it ready to fly?
       ST. AMOUR               Yes, it can fly.

with the regulations and requirements of the Federal Aviation Administration

(“FAA”). See 49 U.S.C. § 46306(b)(9). He was arrested on February 22, 2017.

       In May 2017, St. Amour moved to dismiss the indictment as a matter of

law. 4 St. Amour argued that he had not operated N3482F within the meaning of 49

U.S.C. § 46306(b)(9) because the word “operate” in that provision refers only to

conduct during or imminent to flight. Based on this construction, St. Amour

contended that he did not operate the aircraft because he neither flew nor intended

to fly N3482F on March 27; he taxied and fueled the aircraft for a flight the next

day. Therefore, in effect, St. Amour advocated for a definition of “operate” that

requires a strict “temporal proximity” between the conduct and flight.5

       The Government disagreed. It argued that the term “operate” reaches the

use of an aircraft to prepare for flight, regardless of when that flight is scheduled.

In the Government’s view, the use of an aircraft in preparation for or incident to

flight constitutes “operation” of that aircraft. To support this interpretation, the




       4
          St. Amour also moved on May 26 to dismiss the indictment because of an alleged
violation of the Speedy Trial Act, 18 U.S.C. § 3161(b). We need not discuss this motion since it
is not before us.
       5
         In a hearing on the motion to dismiss, counsel for St. Amour stated that the term
“operates an aircraft” contemplates that “there’s going to be a flight” that is “part of the same
transaction or occurrence” as the act of operation. He argued that “[o]nce the sequence of events
leading up to that plane going airborne are interrupted, it stops there. Then you have to look at
the next series of events.” However, when questioned as to whether St. Amour’s actions were
“preparatory to the flight the following day,” St. Amour’s counsel responded, “Right and
absolutely.”
                                                5

Government pointed out that the safety hazards posed by an unauthorized fuel

system exist both in the air and on the ground.

       In an order on June 19, 2017, the District Court denied the motion to dismiss

the indictment. Before addressing St. Amour’s arguments, the District Court noted

that “the parties have stipulated to the facts and waived any procedural bar to a

merits determination at this stage.”6 The District Court then moved to the merits.




       6
           The parties proffered the following facts as established for purposes of the motion to
dismiss.
       On March 27, 2013, agents of the Drug Enforcement Administration (“DEA”)
       received information from a confidential source (“CS”) that a 1966 Cessna 1821
       aircraft, bearing U.S. registration N3482F (the “Cessna”), was preparing to depart
       Ft. Lauderdale, Florida Executive Airport (“FXE”) with a modification to its fuel
       system. Agents located the Cessna in front of the World Jet Inc. hangars at FXE
       and observed, through the windows of the aircraft, a large, plastic marine fuel
       tank in the back seat held in place with a ratchet strap. A clear hose ran up the
       wing, attached by duct tape, to the actual fuel tank of the plane. A pump inside
       the plane, powered by the plane’s cigarette lighter, was supposed to pump fuel
       from the large plastic tank[.]
       On March 25, 2015, agents from the Department of Transportation interviewed
       Defendant a second time. After waiving his Miranda rights, he provided a sworn
       affidavit admitting that he was aware of the need to obtain FAA approval prior to
       operating an aircraft with fuel modifications such as the one done per his request
       to the Cessna on March 27, 2013, but had not sought or secured such FAA
       approval. Defendant admitted that the purpose of making the fuel system
       modification was to “extend the range” of the Cessna because he was going to
       take the Cessna to South America. In addition, Defendant’s sworn affidavit
       stated:
                 I hired a gentleman Patrick who drilled into the wing cap and the
                 tubes and someone else name[d] Raphael installed the marine gas
                 tank in the cabin rear seat. Once that was done, I taxied the plane
                 to world jet where I got fuel for the plane. I never flew the
                 airplane to South America because the D.E.A. showed up to
                 question about the airplane. I was scheduled to fly the plane to
                 Ascuncion [sic] Paraguay the next day for the owner.
                                                  6

It held that the term “operate” is “clearly broader than the more specific concept of

‘flying’ an aircraft” and that “obtain[ing] fuel for a flight scheduled for the next

day constitute[s] ‘operation’ of an aircraft.” In reaching this result, the District

Court found the Ninth Circuit’s decision in Daily v. Bond, 623 F.2d 624 (9th Cir.

1980) (per curiam), “particularly persuasive because it supports the proposition

that [St. Amour’s] ‘operation’ of the aircraft was ‘for the purpose of air navigation’

because it [was] preparatory to flight.” The District Court declined to define

“exactly how close in time the operation of an aircraft must be in relation to air

navigation to constitute a violation of 49 U.S.C. § 46306(b)(9),” but determined

that St. Amour’s refueling of the aircraft was “sufficiently connected” to the flight

scheduled for the following day.

      After the denial of his motion to dismiss, St. Amour entered a guilty plea but

reserved his right to appeal the denial of his motion to dismiss. 7 On July 24, 2017,

St. Amour filed a notice of appeal challenging the denial of his motion to dismiss.

The same as before, St. Amour argues that the term “operate” is ambiguous as

defined in the United States Code and the Code of Federal Regulations and should

receive a narrow construction that covers conduct during or imminent to flight.


      On March 27, 2013, the Cessna was not being used to provide air transportation
      as that term is used in Title 49, United States Code, Section 46306. On that date,
      Defendant was aware that the fuel system of the Cessna had been modified
      without prior approval from the FAA.
      7
          St. Amour was sentenced to a year of probation and a $100 fine.

                                          II.

                                          A.

      We review a district court’s denial of a motion to dismiss an indictment

under the abuse-of-discretion standard. United States v. Seher, 562 F.3d 1344,

1356 (11th Cir. 2009). However, questions of statutory interpretation are reviewed

de novo. United States v. Segarra, 582 F.3d 1269, 1271 (11th Cir. 2009).

       The interpretation of a statute begins with its language. Watt v. Alaska, 451

U.S. 259, 265, 101 S. Ct. 1673, 1677 (1981). Our first task “is to determine

whether the language at issue has a plain and unambiguous meaning with regard to

a particular dispute.” United States v. Fisher, 289 F.3d 1329, 1337–38 (11th Cir.

2002) (quotation omitted). If so, we need go no further. Id. at 1338. In reading a

statute, we construe it as a whole and avoid “look[ing] at one word or term in

isolation.” United States v. DBB, Inc., 180 F.3d 1277, 1281 (11th Cir. 1999).

      This case concerns the meaning of the term “operates an aircraft” in 49

U.S.C. § 46306(b)(9). That provision states as follows:

      [A] person shall be fined under title 18, imprisoned for not more than
      3 years, or both, if the person . . . operates an aircraft with a fuel tank
      or fuel system that has been installed or modified knowing that the
      tank, system, installation, or modification does not comply with
      regulations and requirements of the Administrator of the Federal
      Aviation Administration.

Id. (emphasis added). The United State Code and Code of Federal Regulations

both define “operate” with respect to aircraft. 8 In the United States Code, the

terms “operate aircraft” and “operation of aircraft” are defined as “using aircraft

for the purposes of air navigation, including . . . the navigation of aircraft . . . and

causing or authorizing the operation of the aircraft with or without the right of

legal control of the aircraft.” 49 U.S.C. § 40102(a)(35). Similarly, the Code of

Federal Regulation states: “Operate, with respect to aircraft, means use, cause to

use or authorize to use aircraft, for the purpose . . . of air navigation including the

piloting of aircraft, with or without the right of legal control (as owner, lessee, or

otherwise).” 14 C.F.R. § 1.1. Thus, as defined, the term “operates an aircraft” in

49 U.S.C. § 46306(b)(9) necessarily encompasses more than the piloting of an

aircraft in flight. It broadly embraces any use of an aircraft for the purpose of air

navigation, including flight itself and actions that are preparatory or incident to

flight.

          The breadth of this definition makes sense given the policies underlying 49

U.S.C. § 46306(b)(9). See United States v. Haun, 494 F.3d 1006, 1009 (11th Cir.

2007) (“The court should adopt that sense of the words which bests harmonizes

with the context, and promotes in the fullest manner the policy and objects of the

legislature.” (quotation omitted)). Among other goals, the federal aviation

          8
        These definitions govern the term “operate” as used throughout the portion of the
United States Code dealing with air commerce and safety, including 49 U.S.C. § 46306.
                                               9
             Case: 17-13352      Date Filed: 03/29/2018    Page: 10 of 15


legislation aims at “assigning, maintaining, and enhancing safety and security as

the highest priorities in air commerce.” 49 U.S.C. § 40101(d)(1). The

Administrator of the FAA is thus directed to “promote safe flight of civil aircraft in

air commerce by prescribing . . . minimum standards required in the interest in

safety for appliances and for the design, material, construction, quality of work,

and performance of aircraft, aircraft engines, and propellers.” Id. § 44701(a)(1).

The prohibition against installing unapproved fuel systems or making non-

compliant modifications furthers this goal of safety. An unapproved fuel system

raises safety concerns regardless of whether an aircraft is in the air or on the

ground because, after all, an explosion or fire may reap devastation in either

location. Moreover, if defined narrowly to only cover conduct during or imminent

to flight, law enforcement would in many cases be unable to stop an aircraft with

an illegal fuel system from taking flight, nullifying the preventative value of the

criminal provision. It thus makes good sense that the term “operates an aircraft” in

49 U.S.C. § 46306(b)(9) reaches any use of an aircraft for the purpose of flight.

      A long line of administrative decisions confirms that “operates an aircraft”

covers uses of an aircraft that are preparatory or incident to the flight of that

aircraft. The NTSB and its predecessor, the CAB, have long held that the word




                                           10
              Case: 17-13352       Date Filed: 03/29/2018      Page: 11 of 15


“operate” means using an aircraft preparatory or incident to flight.9 The CAB first

ruled on this matter in Administrator v. Ruhland, where it held that a person who

started an aircraft’s engine in a maintenance hangar had not operated the aircraft

because he started the engine by accident. 26 C.A.B. 799, 799 (1957). Since the

person acted without intent to fly the aircraft, his actions “were not incident to the

flight of an aircraft and, accordingly, did not constitute ‘operating’ an aircraft.” Id.

In Administrator v. Hise, the CAB considered whether a person was operating an

aircraft when he taxied to a tie-down area and stopped the aircraft, but kept the

engine running. 38 C.A.B. 1237, 1237 (1963). Because these actions were

“directly and necessarily connected with the flight,” the CAB concluded that they

were “incident to the flight of an aircraft.” Id. at 1238 (quoting Ruhland, 26

C.A.B. at 799).

       Years later, after Congress replaced the CAB with the NTSB, the NTSB

decided Administrator v. Pauly, which raised the question whether a person

operated an aircraft by attempting to start it with a jumper cable attached to a car.

2 N.T.S.B. 1369, 1369–71 (1975). In that case, after the aircraft started, it leapt

forward and hit the car, causing property damage and injuring a nearby patrolman.

Id. at 1371. It was “apparent” that the person attempted to start the aircraft with

       9
         See Administrator v. Dailey, 3 N.T.S.B. 1319, 1319–21 (1978); Administrator v.
Collins, 2 N.T.S.B. 1494, 1495–96 (1975); Administrator v. Pauly, 2 N.T.S.B. 1369, 1370
(1975); Administrator v. Hise, 38 C.A.B. 1237, 1237–38 (1963); Administrator v. Kozloff, 27
C.A.B. 1169, 1169–1171 (1958); Administrator v. Ruhland, 26 C.A.B. 799, 799 (1957).

the intent to depart the airport. Id. at 1370. Staying true to the precedent of the

CAB, the NTSB held that the attempted start constituted operation of the aircraft

because it was “preparatory to flight.” Id. at 1370. In another case, Administrator

v. Collins, the NTSB held that the taxiing of an aircraft after landing constituted

operation of the aircraft. 2 N.T.S.B. 1494, 1495–96 (1975). It reasoned that such

taxiing “was ‘incident to the flight of an aircraft,’ in that it was ‘action directly and

necessarily connected with the flight.’” Id. (quoting Hise, 38 C.A.B. at 1238).

      Lastly, in Dailey, a pilot named Dailey attempted to start an aircraft for a

flight, even though the aircraft was under maintenance. 3 N.T.S.B. 1319, 1319–20

(1978). An engine immediately caught fire, forcing Dailey to abort the start and

abandon the aircraft. Id. at 1319. The aircraft itself never moved. Id.

Distinguishing Pauly on the facts, an administrative law judge held that Dailey had

not “operated” the aircraft because it did not move. Id. On appeal, the NTSB

reversed this decision and held that Dailey operated the aircraft because to hold

otherwise would conflict with precedent and defeat the purpose of the regulatory

provision at issue. Id. at 1320.

      Dailey appealed the NTSB decision to the Ninth Circuit. See Daily, 623

F.2d at 625–626. Dailey argued that the starting of the plane was not incident to

flight because the aircraft never moved and “a final decision to fly the plane would

not have been made until the aircraft was at the end of the runway.” Id. at 626.

                                            12
              Case: 17-13352      Date Filed: 03/29/2018   Page: 13 of 15


The Ninth Circuit did not find Dailey’s distinctions “to be meaningful” and held

that “since the attempted start was preparatory to flight, it was for the purpose of

air navigation and thus constituted operation of the aircraft.” Id. (quoting Pauly, 2

N.T.S.B. at 1370). It thus affirmed the decision of the NTSB.

       Therefore, the statutory and regulatory definitions, the objective of safety in

air commerce, and the administrative decisions are all in agreement. A person

operates an aircraft when he uses it for the purpose of air navigation, which

includes flight itself and actions that are preparatory or incident to flight. See 49

U.S.C. § 40102(a)(35); 14 C.F.R. § 1.1. The term “operates an aircraft” therefore

covers the use of an aircraft on the ground—including the starting, taxiing, or

parking of an aircraft—so long as the use was preparatory or incident to flight.

       As defined, we disagree that the term “operates an aircraft” requires a strict

temporal relationship between the use of an aircraft and flight. The statutory and

regulatory definitions make clear that whether a person has operated an aircraft

depends on the purpose for which the person used the aircraft. See 49 U.S.C.

§ 40102(a)(35), 14 C.F.R. § 1.1. The definitions do not speak in terms of time;

they speak only of purpose. Accordingly, when a person uses an aircraft with the

intent for flight, he has operated that aircraft.

                                                 B.

       The present case falls within the scope of the term “operates an aircraft.” St.

Amour started the engine of N3482F and taxied to a maintenance hangar where he

refueled the aircraft to prepare for a flight the next day. Needless to say, an aircraft

cannot fly without fuel; it is a necessary precondition for flight.10 Therefore, St.

Amour operated the aircraft within the meaning of 49 U.S.C. § 46306(b)(9) when

he started, taxied, and fueled N3482F in preparation for the first of his flights on

the voyage to Paraguay. 11 It does not matter that he did not intend to fly N3482F



       10
          In a hearing before the District Court, defense counsel admitted that St. Amour’s
actions were “preparatory to the flight the following day.” Moreover, the District Court asked
St. Amour’s counsel: “Well, why was the plane fueled?” Counsel responded: “Well, to fly at
some point a hundred percent. I mean, I don’t think you’re going to fuel it just to fuel it. You’re
going to fly it.” This makes clear that St. Amour fueled the aircraft for the purposes of flight, not
some other purpose.
       11
           St. Amour argues that the term “operates an aircraft” creates ambiguity sufficient to
trigger the rule of lenity or, if not, to raise a question of unconstitutional vagueness. The rule of
lenity is a canon of statutory construction that “ensures fair warning by so resolving ambiguity in
a criminal statute as to apply it only to conduct clearly covered.” United States v. Svete, 556
F.3d 1157, 1169 (11th Cir. 2009) (quotation omitted). It applies when a grievous ambiguity in
the statute allows no more than a guess as to what Congress intended. Muscarello v. United
States, 524 U.S. 125, 138–39, 118 S. Ct. 1911, 1919 (1998). Here, the rule of lenity does not
require an acquittal of St. Amour because the term “operates an aircraft” does not create the
grievous ambiguity necessary to trigger the rule. By defining “operate” as any use of an aircraft
for the purpose of air navigation, including the piloting of aircraft, the statutory and regulatory
definitions puts individuals on notice that the word “operate” sweeps more broadly than flight or
actions imminent to flight. The rule of lenity has no application to this case.
         St. Amour argues that due process forbids interpreting 49 U.S.C. § 46306(b)(9) to
proscribe conduct which he could not have foreseen within its scope. His problem is that the
statute is not ambiguous. United States v. Lanier, 520 U.S. 259, 266, 117 S. Ct. 1219, 1225
(1997) (“[T]he vagueness doctrine bars enforcement of a statute which either forbids or requires
the doing of an act in terms so vague that men of common intelligence must necessarily guess at
its meaning and differ as to its application.” (quotation omitted)). Section 46306(b)(9) forbids a
person from operating an aircraft with an unapproved fuel tank, where “operate” is defined to
                                                 14

mean using an aircraft for the purpose of air navigation—including but not limited to piloting an
aircraft. A person of common intelligence would understand that this language reaches uses of
an aircraft done in preparation for or incident to the flight of an aircraft.
