Risk analysis
means the process
whereby a hazard is characterized for
its likelihood and the severity of its ef-
fect or harm. Risk analysis can be ei-
ther a quantitative or qualitative anal-
ysis; however, the inability to quantify
or the lack of historical data on a par-
ticular hazard does not preclude the
need for analysis.
Risk mitigation
means any action
taken to reduce the risk of a hazard’s
effect.
Safety area
means a defined area com-
prised of either a runway or taxiway
and the surrounding surfaces that is
prepared or suitable for reducing the
risk of damage to aircraft in the event
of an undershoot, overshoot, or excur-
sion from a runway or the uninten-
tional departure from a taxiway.
Safety assurance
means processes
within the SMS that function system-
atically to ensure the performance and
effectiveness of risk controls or mitiga-
tions and that the organization meets
or exceeds its safety objectives through
the collection, analysis, and assess-
ment of information.
Safety policy
means the certificate
holder’s documented commitment to
safety, which defines its safety objec-
tives and the accountabilities and re-
sponsibilities of its employees in re-
gard to safety.
Safety promotion
means a combina-
tion of training and communication of
safety information to support the im-
plementation and operation of a SMS
in an organization.
Safety risk management
means a proc-
ess within the SMS composed of de-
scribing the system, identifying the
hazards, and analyzing, assessing, and
controlling or mitigating the risk.
Scheduled operation
means any com-
mon carriage passenger-carrying oper-
ation for compensation or hire con-
ducted by an air carrier for which the
air carrier or its representatives offers
in advance the departure location, de-
parture time, and arrival location. It
does not include any operation that is
conducted as a supplemental operation
under 14 CFR part 121 or public charter
operations under 14 CFR part 380.
Shared-use airport
means a U.S. Gov-
ernment-owned airport that is co-lo-

§ 139.1(a) and at which portions of the
movement areas and safety areas are
shared by both parties.
Unscheduled operation
means any
common carriage passenger-carrying
operation for compensation or hire,
using aircraft designed for at least 31
passenger seats, conducted by an air
carrier for which the departure time,
departure location, and arrival loca-

the customer or the customer’s rep-
resentative. It includes any passenger-
carrying supplemental operation con-
ducted under 14 CFR part 121 and any
passenger-carrying public charter oper-
ation conducted under 14 CFR part 380.
Wildlife hazard

a damaging aircraft collision with
wildlife on or near an airport. As used

Special Statutory Requirement To Op-
erate to or From a Part 139 Airport.
Each air

which the public is provided in advance a
schedule containing the departure location,
departure time, and arrival location of the
flight must operate to and from an airport
certificated under part 139 of this chapter in
accordance with 49 U.S.C. 41104(b). That stat-

air carriers that conduct public charter oper-
ations under 14 CFR part 380 are covered by
the statutory requirements to operate to and
from part 139 airports. See 49 U.S.C. 41104(b).
