time/temperature indicator
time/temperature indicator Also called Smart Label,
colour-coded sticker attached to galley trolley; changes
colour with refrigerated contents. Upon activation turns
green [17- hour life], turning yellow upon time/temperature
expiry.
time/temperature cycle recorder Records time engine
spends at critically high TGT, to give realistic indication
of hot-end life.
time tic Time reference mark along telemetry readout;
usually small inverted V every second along straight timebase.
time tick Regular time signal of one or more audible
brief sounds.
time to go In air intercept, time to fly to offset point from
any other initial position; after offset point, time to fly to
intercept point (DoD).
time-triggered protocol A data-communication platform.
time zone Regions of local standard time, esp. over sea
areas, where they are exactly divided by 15° widths of
longitude.
timing 1 Angular positions of piston-engine crankshaft
at which valves first rise from seats or touch them again,
and at which spark occurs; also called valve *, ignition *.
2 In US, assessment of human pilot’s ability to coordinate
flight controls on correct time basis for smooth
manoeuvres; not often regarded as a topic elsewhere
unless demonstrably faulty.
timing consideration Measure of time missile (or,
possibly, other weapon such as aeroplane) is exposed on
ground between withdrawal from hardened shelter and
launch (probably arch.).
timing disc Disc, engraved marking or other feature on
piston engine to assist establishing exact crankshaft
angular positions for timing purposes.
timing parallax Film distance between time signal (2)
and corresponding frame of imagery.
timing pulse Pulse used as time reference in telemetry,
radar and SSR and other electronic systems.
TiMMC Titanium metal-matrix composite.
Timos Total-implant MOS device or circuit.
Tims, TIMS 1 Technology integration of missile
subsystems.
2 Tactical information management system.
3 Training Integration Management System, flight
scheduling and student records (USAF).
tin 1 Soft white metal, density 7.31, MPt 231.85°C,
symbol Sn (stannum).
2 To coat surface of mild steel sheet with tin to prevent
corrosion.
3 To coat metal surface with solder before making joint.
4 Aircraft, not necessarily metal (US colloq.).
Tina Thermal-imaging navigation aid.
tineways Channels in ULD mating with tines of a forklift.
tinfish Torpedo (UK colloq.).
TINS, Tins Thermal-imaging navigation system, or set.
Tinsel Transmitter carried by bomber to jam ground
instructions to German fighters (RAF WW2).
tin-strip Metal prefabricated-plank airstrip for STOVL.
t int Integration time, especially radar filter integration
time.
tin-tray game Stewardess trolley race.
tin wing Lightplane whose wings are metal-skinned.
tip loss
TIO US piston engine designation: turbocharged, direct
injection, opposed.
TIOS Two-in-one service (Satcoms).
TIP 1 Message code: until past specified waypoint or
other point (ICAO).
2 Tracking and impact prediction.
3 Technical information panel (Agard).
4 Test integration plan.
5 Tailored instruction program (US).
6 Threat image projection, to test X-ray baggage
screeners.
7 Technical improvement program, or technically
improved product (IFF).
8 Transit improvement program.
9 Tiros information processor.
tip 1 Extremity of aerofoil.
2 Angle of rotation of reconnaissance camera about
aircraft transverse axis; also called pitch.
3 Wing-tip fuel tank (DoD) (colloq., adjective).
tip aileron Aileron forming most or all of tip of wing.
tip-back angle In aircraft with nosewheel landing gear,
the angle between the vertical through the plane of ground
contact of the rearmost MLG wheels and the plane
through the ground contact line and the centre of gravity;
symbol β.
tip cargo Special cargo, eg radioactive isotopes, carried
in small compartment in wingtip of some transports.
tip chord Chord at tip of aerofoil, esp. wing, normally
measured parallel to plane or symmetry of wing (for
variable-sweep, at minimum sweep angle) between points
where straight leading/trailing edges meet curvature at tip.
Where both edges have pronounced sweep at tip, or where
they are joined by line not parallel to plane of symmetry
(eg Lightning, Tornado) other definitions apply, often
unique to type.
tip cropping Cutting off at Mach angle.
tip dragger 1 Spoiler above wingtip used asymmetrically
to cause yaw.
2 Sailplane (colloq.).
tip drive Rotation of main rotor(s) of rotocraft by thrust
applied at or near tips.
tip droop Downward folding of wingtips through large
angle, usually 60°–80°, to move forward aerodynamic
centre of wing at supersonic speed and decrease trim drag;
in some aircraft (XB-70) also generated compression lift.
tip fins 1 The obvious meaning, fixed fins at the tip of a
wing or horizontal tail.
2 Ridges across the tip of a turbine rotor blade which
almost touch between the surrounding seal segments to
form a labyrinth.
tip float See stabilizing float.
tip generator Wingtip vortex generator.
TIPH Taxi into position [on runway] and hold, possibly
to be discontinued practice (FAA).
TIPI Tactical information processing and interpretation
system (USAF).
tip in To bank steeply away from takeoff flight path.
tip jet Any system providing propulsive thrust at the tip
of a helicopter main-rotor blade: pressure jet, cold
[compressed-air] jet, ramjet, pulsejet, rocket or turbojet.
tip loss Inefficiency of tip of aerofoil in lifting mode
caused by spanwise deflection of isobars and relative
wind, in some transonic cases approaching 90° and
making tip mere dead weight.
