wing skin
wing skin Usually refers to large stressed skin forming
upper or lower surface of wing box; largest single piece of
material in aircraft.
wing slot Slot built into wing; extends through outer
wing from lower to upper surface with profile generally
similar to that left by open slat.
wing spar Principal spanwise member of wing, in
traditional or light aircraft usually isolated but in modern
stressed-skin wing forming one face of wing box which
itself behaves as a spar. Always extends full available
depth, unlike stringers. In slender delta built perpendicular
to longitudinal axis, thus in such wings there are
many spars which terminate not at tip but at points along
leading edge.
wing spread See span.
wing strut Primary structural links joining wings of
biplane (interplane struts) or bracing high-wing monoplane
diagonally to fuselage (such are actually ties in flight
but struts on ground).
wing sweep See sweep.
wing tanks 1 Tanks, normally for fuel, either accommodated
in wing or (integral) formed by sealing wing box.
2 Wing-mounted drop tanks where aircraft also has
drop tanks elsewhere; thus ** may be dropped first to
permit sweep to be increased.
wingtip Outer extremity of wing; either extreme tip or
general area.
wingtip aileron Aileron forming entire tip of wing, either
with chordwise inner end or extending inboard along
trailing edge.
wingtip extension Increase of span by adding at tip at
same dihedral angle as wing.
wingtip fence Winglet of very low aspect ratio.
wingtip flare Pyrotechnic attached to wingtip and
ignited by pilot to assist night landing (obs. technique).
wingtip float Stabilizing float of flying boat, usually
inboard from wingtip.
wingtip handler Person walking beside sailplane being
towed across airfield holding one tip so that wings are
level.
wingtip rake See rake.
wingtip sail Winglet, especially prominent.
wingtip tank External fuel tank, jettisonable or not,
carried on wingtip.
wingtip vortex generator Ducted windmill at wingtip
providing shaft power. Does the opposite of generating
vortex.
wingtip vortices See vortex; always present off tips of
conventional wings at lifting AOA, and when intense (eg
tight turn) pressure at centre falls so low that moisture
condenses to leave white visible trail.
wing truss Wing plus all bracing struts and wires transmitting
loads to or from fuselage.
wingunder Bunt [suggest unpremeditated].
wing waggle Waggle.
wing walk Area marked in upper surface where maintenance
engineers may walk in soft shoes.
Wing Walk Patented brushed-on paint for walkways
offering high coefficient of friction.
wing walker 1 Passenger, invariably attractive girl, who
seldom walks but rides standing securely attached to
upper centre section of biplane at airshow.
2 Person[s] required to hold a wingtip of taxiing aircraft
to prevent unwamted weathercocking.
wireless telegraphy
wing warping Lateral control by warping; called
primary on lower wing of biplane, secondary on upper.
Relies on wing torsional flexure (see also warping).
wing yawmeter Yawmeter in form of miniature wing,
aligned vertically or (for AOA) horizontally, with sensing
holes at 0.15 or less chord.
WINN, Winn Weather information network (NASA,
Honeywell and others).
WINS, Wins 1 Workshop in negotiating skills.
2 Wireless instrumentation station [sometimes WIS].
3 Wireless integrated network sensor.
WINTEM Upper wind[s] and temperature[s].
winterization Process of equipping aircraft for flight in
Arctic-type environment; obviously includes full antiicing
and de-icing of airframe, engines, propellers and
flight-deck windows and extends to landing gears,
systems, fluid specifications and many items of GSE.
winter solstice Point on ecliptic occupied by Sun at
maximum southerly declination, around 22 December.
WIP Work in progress [i.e., check if field is open].
wipe-off switch Attached externally under belly or
engine pod in most vulnerable place in belly landing; triggers
safety system, eg tank inerting or fire extinguishers.

Wipps, WIPPS Wideband integrated platform protection
system.
Wire Wide-field IR explorer.
wire 1 See fly by *.
2 Misleadingly in common use for the multi-wire cables
used to arrest aircraft on carriers.
wire braid Woven covering over ignition cables to
prevent escape of emissions causing radio interference.
wire bundle Large group of electrical wires individually
tagged, clipped together and then attached as a unit to
structure, usually in wireway.
wired 1 Fitted with locking wire.
2 Acronym, wind-tunnel integrated RTIC/RTOC
experiments and demonstrations.
wired program One employing wired storage; also called
fixed program.
wire-drawing 1 Manufacture of wire of required diameter
by drawing through circular die.
2 Part-throttling fluid flow by passage through
constriction (colloq.).
wired storage EDP (1) storage which was originally literally
wired in and could be erased only by physically
removing it; today any indestructable storage (usually for
ROM).
wire edge Sharp burr along edge of sheet freshly cut by
shear.
wire gauge 1 Measure of diameter of wire or thickness of
sheet; in UK by SWG measure based on Imperial
(0.001–0.5 in).
2 Hand gauge for measurement of sheet thickness or
wire diameter.
wire group Several wires routed to common destination
and tied by clips.
wire guidance Command guidance of missile or other
vehicle by electrical signals (bang/bang or analog)
conveyed along fine wires unrolled behind vehicle and
used to position surfaces governing trajectory.
wireless telegraphy Transmission of Morse by radio.
