T
Tacking: Hand stitching usually concentrated at a
single point or around a certain point.
Tandem: A parachute system utilizing a dual
harness configuration. Used for carrying
a passenger who is attached to the front
of the harness/container system - worn
and controlled by a Tandem
Pilot/Instructor.
Tandem Master:
(Tandem Pilot)
A manufacturer’s rating authorizing an
individual to conduct tandem jumps with
a passenger. It is not a granted CSPA
rating.
Target: The intended landing area i.e. Bowl,
tuffet, etc.
Technical
FAA document which dictates that
Standard Order certificated parachuting equipment meet
(TSO):
minimum performance standards
(TSOC23D/AS8015B).
Temporary Pin: Locking pin used to hold a container
closed until the ripcord pin can be
inserted. Must be removed before use!
Terminal Velocity: The maximum attainable falling speed,
for any given body position, when force
of gravity; force of aerodynamic drag
(approximately 120 mph).
Tertiary
A third parachute (round) normally used
Parachute: as a back-up when doing intentional
break-aways from main parachute. Also,
has been used by Canopy Formation
jumpers in case of canopy “wraps”.
Throw-Out: See hand deploy.
Three (3)-Ring: A system of main canopy release used
on most sport equipment.
Tilt: A term describing a body’s angle or twist
in freefall; the resulting deflection of air
generates movement.
Total Malfunction: A situation where the main parachute
system fails to leave the container
resulting in a “high-speed” malfunction.
Toggle: A wooden or plastic knob attached to
the steering lines. Also see Steering
Loops.
Trim: The process to adjust the line lengths of
a parachute.
Track: Body position used to attain maximum
horizontal velocity in freefall, with
minimum increase in vertical velocity.
Training Ripcord: Ripcord handle used for training student
jumpers the proper technique for pulling
the reserve ripcord.
Tumble: Uncontrolled rotation about any axis.
Type-Rated: A rigger who has gained experience on
specific types of equipment and has
been endorsed for same.
Uncontrolled: Falling out of control -
unintentional manoeuvres.
U
V
Validation: An act of ratification or official approval.
In CSPA terms, the act of approving a
performance or an element of one.

Velcro: Hook and pile (touch) fastener.
Velocity: Rate of motion. Speed—rate of change
of position.
Vent: Openings in the canopy to allow the
controlled escape of air.
Verification: The process of checking and
assembling evidence with a view to
validating performances.
Vertical: Straight up and/or down.
Vigil: AAD manufactured by Advanced
Aerospace Designs
W
Water Jump: A jump where the intended landing area
is water.
Webbing: Nylon support material used in
construction of parachute harnesses.
Whuffo: A derogatory term used by skydivers to
describe spectators.
Wind: Air in motion.
Wind Cone: Area contained by the extremities of
lateral movement (crabbing) of a
steerable canopy, with the apex at the
centre of target.
Wind Drift
Indicator (WDI):
A streamer, usually made of crepe
paper, dropped over the target area. It
should have the same rate of descent
as a canopy so as to reveal the amount
of drift a non-steerable canopy would
encounter during descent between
opening altitude and the surface.
Wind Line: An imaginary line, parallel to wind
direction and intersecting the centre of
the landing area, or apex of the wind
cone.
Wind Sock: Elevated cone of material which
indicates the direction and approximate
wind velocity.
Working Time: The time allowed for turning points in a
competition dive. i.e. 4-way FS = 35
seconds.
Wrist Mount: Used for mounting instruments on the
wrist.
Z
Z: Lack of control of the body, out of
control.
Zap: To intentionally throw another
parachutist out of control during a group
jump. To pull another parachutist’s
ripcord above normal opening altitude
(dangerous stunt).
Zero-momentum: See non-momentum.
