Limaçon
Limaçon Quartic curve, r = a cos θ + b.
Limar Laser imaging and ranging.
limb Visible edge of heavenly body, esp. the Sun.
limit altitudes Angles of pitch or bank which FCS
prevents being exceeded.
limit-cycle oscillation Sustained vibration at a fixed
frequency and limited amplitude.
limited navaids This usually means sextant only; electronic
aids unavailable.
limited panel Pilot instruction with key flight instruments
obliterated and external cues absent (originally
meant gyro instruments obliterated, and always horizon;
today depends on panel).
limited remote communications outlet Unmanned satellite
air/ground com. facility operated as LRCO-A, VOR
voice channel plus receiver, or LRCO-B, separate facility
with transmit and receive capability, extending FSS
service area (FAA).
limited-route concept Operator, captain or whoever else
prepares flight-plan, is offered very limited choice of
routes through a controlled airspace.
limiter One meaning is control device attached to transducer
to prevent critical or threshold value being
exceeded.
limiter spiral Manoeuvre in which aircraft makes g-
loaded roll on AOA limit, a form of corkscrew with stick
in fully back L or R corner.
limiting load factor See design load factor.
limiting Mach number Maximum permitted for type of
aircraft, usually before onset of buffet.
limiting runway One whose length, altitude or temperature
necessitates take-off below MTOW.
limiting speed 1 Maximum IAS permitted in particular
aircraft configuration, eg landing gear down.
2 Speed in any flight condition in which longitudinal
acceleration is zero.
limiting velocity Terminal velocity at specified angle to
horizontal [not normal term].
limit load Greatest anticipated stress on structural
member, unfactored, from authorized ground and flight
operation.
limit of proportionality Tensile (rarely, other) stress at
which material begins to suffer plastic deformation,
acquiring permanent set.
limits 1 Weather minima permitted for particular pilot
or flight.
2 Boundaries of flight regimes, eg IAS or g in particular
configurations.
limit switch Subsystem, which, normally automatically,
varies the authority of a control, e.g.. changing the range
of elevator movement available according to IAS or other
parameter.
Limnatran Limited North Atlantic regional air navigation.
LiMnO 2 Lithium manganese dioxide electric battery.
LIMSS Logistics information management support
system [hence LIMS, management system].
Linac Linear accelerator for X-radiography.
Linas Laser-inertial nav/attack system.
Lincs 1 Leased-products interfacility national air space
communications system; digital net connecting remote
radar and Wx sites to ATC centres (FAA).
2 Long-haul interfacility com. system.
Lindberg detector Fire detector with sealed network of
line-replaceable
stainless-steel tubing containing material which above set
temperature emits gas, raising pressure.
Lindholme gear Air/sea rescue equipment dropped to
survivors; the original form (1942) was packaged in 10
buoyant containers.
line 1 Single pipe in fluid system.
2 Single cable in electrical system.
3 Horizontal scan on raster display.
4 Cable or rope anchored to aerostat with other end
free.
5 Flight-line.
6 Adjective, in revenue service with air carrier.
7 Future path of target.
8 Personal boast, from ‘shooting a *’ (RAF).
linear accelerator In theory, any assisted-takeoff device.
In practice, restricted to an “unrolled” electric motor.
linear aerial array Yagi or other array of dipoles on
straight axis.
linear aerospike Rocket with two-dimensional expansive
nozzle.
linear building One in which operations take place in
sequence from one end to other.
linear configuration Vehicle assembled from separable
stages arranged end to end in one line.
linear friction welding Workpieces are rubbed together
to reach welding temperature, giving a perfect bond by a
solid-state process not involving melting.
linear hold Usually, to delay landing by intercepting
extended runway centreline far from airport, advising
when 1,000 m from threshold.
linear motion See heave, surge, sway.
linear optical sensor Transducer in fibre-optic sensor
system which, by splitting and reflecting laser pulses
whose phase-displacement is then measured, translates
mechanical movement (eg, of aileron) into a decodable
output.
linear-scale instrument Vertical or horizontal straightline
display, either tape or video, giving quantified output.
linear shaped charge Explosive cord whose cross-section
is that of hollow (shaped) charge, for unidirectional
cutting.
line book Written and witnessed record of lines (8) shot
by members of Mess (RAF).
line check Examination of crew qualified on type but
proving ability to fly new route.
line inspection Usually vague, but generally a special
check not calling for aircraft to be moved to maintenance
or engineering area or enter hangar.
lineman Engineer, marshaller or other flight-line
worker, esp. in general aviation.
line-mounted Usually, supported entirely by a pipe or
cable, thus * valve.
line of position See position line.
line of reference The intersection of the planes of reference
and of symmetry.
line oriented flight training Training (in air or simulator)
of commercial aircrew flying as a crew and using SIDs and
STARs and other regular procedures, esp. on routes of
pupils’ airline.
line-oriented safety audit Collection of safety data and
flight-crew performance as diagnostic tool.
liner Sheet or sprayed-on heat insulator in some (noncase-bonded)
solid motors.
line-replaceable Capable of being removed from aircraft
