T Flashcards
Tactical air navigation (TACAN)
An electronic navigation
system used by military aircraft, providing both distance and
direction information.
Takeoff decision speed (V1)
Per 14 CFR section 23.51:
“the calibrated airspeed on the ground at which, as a result
of engine failure or other reasons, the pilot assumed to have
made a decision to continue or discontinue the takeoff.”
Takeoff distance
Per 14 CFR section 23.51:
“the calibrated airspeed on the ground at which, as a result
of engine failure or other reasons, the pilot assumed to have
made a decision to continue or discontinue the takeoff.”
Takeoff safety speed (V2)
Per 14 CFR section 23.51:
“the calibrated airspeed on the ground at which, as a result
of engine failure or other reasons, the pilot assumed to have
made a decision to continue or discontinue the takeoff.”
Taxiway lights
Omnidirectional lights that outline the edges
of the taxiway and are blue in color.
Taxiway turnoff lights
Lights that are flush with the runway
which emit a steady green color.
Technique
The manner in which procedures are executed
Telephone information briefing service (TIBS)
Telephone recording of area and/or route meteorological
briefings, airspace procedures, and special aviation-oriented
announcements.
Temporary flight restriction (TFR)
Restriction to flight
imposed in order to:
1. Protect persons and property in the air or on the
surface from an existing or imminent flight associated
hazard;
2. Provide a safe environment for the operation of
disaster relief aircraft;
3. Prevent an unsafe congestion of sightseeing aircraft
above an incident;
4. Protect the President, Vice President, or other public
figures; and,
5. Provide a safe environment for space agency
operations.
Pilots are expected to check appropriate NOTAMs during
flight planning when conducting flight in an area where a
temporary flight restriction is in effect.
Tension
Maintaining an excessively strong grip on the control
column, usually resulting in an overcontrolled situation.
Terminal aerodrome forecast (TAF)
A report established
for the 5 statute mile radius around an airport. Utilizes the
same descriptors and abbreviations as the METAR report.
Terminal arrival area (TAA)
A procedure to provide a
new transition method for arriving aircraft equipped with
FMS and/or GPS navigational equipment. The TAA contains
a “T” structure that normally provides a NoPT for aircraft
using the approach.
Terminal instrument approach procedure (TERP)
Prescribes standardized methods for use in designing
instrument flight procedures
Terminal radar service areas (TRSA)
Areas where
participating pilots can receive additional radar services. The
purpose of the service is to provide separation between all
IFR operations and participating VFR aircraft.
Terrain awareness and warning system (TAWS)
A
timed-based system that provides information concerning
potential hazards with fixed objects by using GPS positioning
and a database of terrain and obstructions to provide true
predictability of the upcoming terrain and obstacles
Thermosphere
The last layer of the atmosphere that
begins above the mesosphere and gradually fades away into
space.
Threshold crossing height (TCH)
The theoretical height
above the runway threshold at which the aircraft’s glideslope
antenna would be if the aircraft maintained the trajectory
established by the mean ILS glideslope or MLS glidepath.
Thrust
The force which imparts a change in the velocity of a
mass. This force is measured in pounds but has no element of
time or rate. The term “thrust required” is generally associated
with jet engines. A forward force which propels the airplane
through the air.
Thrust (aerodynamic force)
The forward aerodynamic
force produced by a propeller, fan, or turbojet engine as it
forces a mass of air to the rear, behind the aircraft.
Thrust line
An imaginary line passing through the center of
the propeller hub, perpendicular to the plane of the propeller
rotation.
Time and speed table
A table depicted on an instrument
approach procedure chart that identifies the distance from the
FAF to the MAP, and provides the time required to transit
that distance based on various groundspeeds.
Timed turn
A turn in which the clock and the turn
coordinator are used to change heading a definite number of
degrees in a given time.
Torque
(1) A resistance to turning or twisting. (2) Forces that
produce a twisting or rotating motion. (3) In an airplane, the
tendency of the aircraft to turn (roll) in the opposite direction
of rotation of the engine and propeller. (4) In helicopters with
a single, main rotor system, the tendency of the helicopter to turn in the opposite direction of the main rotor rotation
Torquemeter
An instrument used with some of the larger
reciprocating engines and turboprop or turboshaft engines to
measure the reaction between the propeller reduction gears
and the engine case.
