stochastic Implying presence of unknown or random
variable; thus, * process is ordered set of observations,
each a sample from a probability distribution.

removed during manufacture.
stockpile/target sequence, STS Order of events in
removing NW from storage and assembling, testing,
transporting and delivering to target (DoD).
stocks Shaped supports on which flying-boat hull is
built, but in no sense tooling.
stock template, ST One developed by trial and error,
esp. for parts undergoing severe deformation.

radius r] falling through fluid [density ρ o , dynamic
viscosity η] is V = ––––

Stoner Mudge Patented technique of coating integral
tanks with rubbery sealant.
stonk To destroy a surface target [verb or noun],
(colloq.).
stooge To fly aimlessly in order to stay in particular area
(eg awaiting orders, or in hope of encountering enemy).
stooping Atmospheric refractive phenomenon in which
image (mirage) of distant object is vertically foreshortened.
STOP Structural/thermal/optical program.
stop(s) Mechanical limiter(s) to permissible travel of
flying-control or other mechanism.
stop alt squawk Turn off altitude-reporting switch and
continue Mode C framing pulses.
stop-and-go See circuit.
stop countersink Fitted with collar to limit penetration.
stop drill 1 See stop hole.
2 Drill with collar to limit penetration.
stop gap A quick, temporary solution.
Storm
stop hole Hole drilled in end of fatigue crack to provide
larger radius and halt further spread.
stop nut Nut which stops in place without further action
(such as wiring or bending up tabs).
stopover 1 Stop by pax at intermediate airport authorized
by ticket for prescribed period.
2 One-night stay away from base by slip crew (civil or
military).
stopped-rotor aircraft See stowed rotor aircraft.
stopping Loosely, sealer for cracks, esp. in pressurized
riveted joint.
stop squawk Switch off transponder, or a particular
mode.
stopway 1 Defined rectangular area on ground at end of
runway in direction of takeoff (ie beyond upwind end,
symmetrical about extended CL) prepared as a suitable
area in which aircraft can be stopped in case of abandoned
takeoff (ICAO).
2 Area beyond takeoff runway, no less wide and
centred upon extended CL, able to support aircraft during
aborted takeoff without causing structural damage to it
and thus designated for use (FAA).
stop weld, stop-weld Material, usually in form of paint,
which has so high a melting point that it is not fused by
any conventional welding process. Inserted as applied
layer along line followed in seam-welding, results in
treated area remaining unwelded.
storage Generalized term for any kind of memory in
EDP (1), display technology, EW and similar disciplines.
Not normally used in aircraft for fuel or other consumables,
ordnance and ammunition or cargo/baggage.
storage CRT Various families able to write information
into a storage surface by adding/subtracting from an
initial potential; most configurations have symmetrical
layout with write gun at one end and read gun at other.
storage oil Intended as corrosion preventative, for
engines [especially piston engines], usually mineral or
other oil plus corrosion inhibitor.
storage system In electronics and displays, basically
comprising direct-view storage tubes and those in which
storage is entirely separate; invariably concerned with
vector inputs, converted into analog (beam-deflection)
signals and varying luminance.
storage tube See storage CRT.
Storc Satellite tracking of RV convoys.
store 1 Basic element of EDP (1) storage; normally a
bistable device accommodating one bit.
2 Generalized adjective for storage, hence * address,
etc.
3 To place information in memory for future reading.
4 Generalized term for any mission-related payload
carried by combat aircraft in form of discrete streamlined
device either carried externally or released from internal
bay; anything that occupies a pylon or ERU, whether
intended for air-dropping or not.
