Q

Temporary flight restriction (TFR)

A

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

Q

Thrust

Q

Torque

A

(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

24
Q

A

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.

resulting in a balance of control forces.

41
Q

Tropopause

A

The boundary layer between the troposphere
and the mesosphere which acts as a lid to confine most
of the water vapor, and the associated weather, to the
troposphere.

42

A

The vertical distance of the airplane above
sea level—the actual altitude. It is often expressed as feet
above mean sea level (MSL). Airport, terrain, and obstacle
elevations on aeronautical charts are true altitudes.

45
Q

Truss

A

A fuselage design made up of supporting structural members that resist deformation by applied loads. The truss-type fuselage is constructed of steel or aluminum tubing. Strength and rigidity is achieved by welding the tubing together into a series of triangular shapes, called trusses.

48
Q

Turbine engine

A

An aircraft engine which consists of an
air compressor, a combustion section, and a turbine. Thrust
is produced by increasing the velocity of the air flowing
through the engine.

49
Q

Turbocharger

A

An air compressor driven by exhaust gases,
which increases the pressure of the air going into the engine
through the carburetor or fuel injection system.

50
Q

Turbofan engine

A

A fanlike turbojet engine designed to
create additional thrust by diverting a secondary airflow
around the combustion chamber.

51
Q

Turbojet engine

A

A turbine engine which produces its thrust

entirely by accelerating the air through the engine.

52
Q

Turboprop engine

A

A turbine engine which drives a
propeller through a reduction gearing arrangement. Most of
the energy in the exhaust gases is converted into torque, rather
than using its acceleration to drive the aircraft.

53
Q

Turboshaft engine

A

A gas turbine engine that delivers power through a shaft to operate something other than a propeller.

54
Q

Turn-and-flip indicator

A

A flight instrument consisting
of a rate gyro to indicate the rate of yaw and a curved glass
inclinometer to indicate the relationship between gravity and
centrifugal force. The turn-and-slip indicator indicates the
relationship between angle of bank and rate of yaw. Also
called a turn-and-bank indicator.

55
Q

Turn coordinator

A

A rate gyro that senses both roll and
yaw due to the gimbal being canted. Has largely replaced
the turn-and-slip indicator in modern aircraft.
