and efficient operation of the small unmanned aircraft in the national airspace system.
Special VFR conditions mean meteorological conditions that are less than
those required for basic VFR flight in
controlled airspace and in which some
aircraft are permitted flight under visual flight rules.
Special VFR operations means aircraft
operating in accordance with clearances within controlled airspace in meteorological conditions less than the
basic VFR weather minima. Such operations must be requested by the pilot
and approved by ATC.
Standard atmosphere means the atmosphere defined in U.S. Standard Atmosphere, 1962 (Geopotential altitude
tables).
Stopway means an area beyond the
takeoff runway, no less wide than the
runway and centered upon the extended centerline of the runway, able
to support the airplane during an
aborted takeoff, without causing structural damage to the airplane, and designated by the airport authorities for
use in decelerating the airplane during
an aborted takeoff.
Suitable RNAV system is an RNAV system that meets the required performance established for a type of operation, e.g. IFR; and is suitable for operation over the route to be flown in
terms of any performance criteria (including accuracy) established by the
air navigation service provider for certain routes (e.g. oceanic, ATS routes,
and IAPs). An RNAV system-s suitability is dependent upon the availability of ground and/or satellite navigation aids that are needed to meet
any route performance criteria that
may be prescribed in route specifications to navigate the aircraft along the
route to be flown. Information on suitable RNAV systems is published in
FAA guidance material.
Synthetic vision means a computergenerated image of the external scene
topography from the perspective of the
flight deck that is derived from aircraft attitude, high-precision navigation solution, and database of terrain,
obstacles and relevant cultural features.
Synthetic vision system means an
electronic means to display a synthetic

vision image of the external scene topography to the flight crew.
Takeoff power:
(1) With respect to reciprocating engines, means the brake horsepower
that is developed under standard sea
level conditions, and under the maximum conditions of crankshaft rotational speed and engine manifold pressure approved for the normal takeoff,
and limited in continuous use to the
period of time shown in the approved
engine specification; and
(2) With respect to turbine engines,
means the brake horsepower that is developed under static conditions at a
specified altitude and atmospheric
temperature, and under the maximum
conditions of rotor shaft rotational
speed and gas temperature approved for
the normal takeoff, and limited in continuous use to the period of time shown
in the approved engine specification.
Takeoff safety speed means a referenced airspeed obtained after lift-off
at which the required one-engine-inoperative climb performance can be
achieved.
Takeoff thrust, with respect to turbine engines, means the jet thrust that
is developed under static conditions at
a specific altitude and atmospheric
temperature under the maximum conditions of rotorshaft rotational speed
and gas temperature approved for the
normal takeoff, and limited in continuous use to the period of time shown in
the approved engine specification.
Tandem wing configuration means a
configuration having two wings of
similar span, mounted in tandem.
TCAS I means a TCAS that utilizes
interrogations of, and replies from, airborne radar beacon transponders and
provides traffic advisories to the pilot.
TCAS II means a TCAS that utilizes
interrogations of, and replies from airborne radar beacon transponders and
provides traffic advisories and resolution advisories in the vertical plane.
TCAS III means a TCAS that utilizes
interrogation of, and replies from, airborne radar beacon transponders and
provides traffic advisories and resolution advisories in the vertical and horizontal planes to the pilot.
Time in service, with respect to maintenance time records, means the time
from the moment an aircraft leaves the
