SAE 1 Society of Automotive Engineers. The Society
publishes thousands of internationally accepted specifications
and manuals of design practice, many of which [such
as numerous ARP documents] are aeronautical. Office
Warrendale, PA15096. (US).

viscosity.

4 Spanish air force [UK usage].
5 Satellite application facilities.
6 Sallskapet for Astronautisk Forskning [astronautical
soc.] (Finland).
SAFA Safety assessment of foreign aircraft (ECAC,
USAF).

Association, now simply SAFE Association [Canoga
Park, CA] (US).
2 Soil airfield fighter environment (DoD).

Safe-bar Safeland barrier.
safe burst height That above which damage/fallout is
locally acceptable.
Safecon Safety and Flight Evaluation Conference
(NIFA).
SAFEE Security of aircraft in the future European environment.
Safe Flight kit AOA-sensitive stall-warning system
normally displaying green arrows on glareshield of GA
aircraft.
Safegrip Proprietary anti-icing/deicing fluid, based on
potassium acetate.
safe life Basic design and certification philosophy for
primary structure; whether or not there are redundant
load paths or fail-safe provisions, a total acceptable life
(flight time) is published in flight manual and relevant
structure must then be replaced, even if no crack is visible.
safe line Boundary of airspace within which unarmed
[surveillance or tanker] aircraft can operate.
Safer 1 System for aircrew flight extension and return;
lifting/propelled ejection capsule.
2 Special aviation fire and explosion reduction (FAA
panel, US, from 1977).
safety As verb, see safetying.
safety zone
safety advisory Issued by ATC to aircraft under its
control to warn of (1) terrain obstruction and (2) aircraft
conflict, in the judgement of the controller (FAA).
safety altitude Loosely, one at which collision with
surface is unlikely at approximate location; not accepted
term (see DH, MDA, etc).
safety analysis Investigation of likely consequences of
all failures [of an item] likely to occur.
safety area Designated area around helicopter, ICAO =
0.25 overall length [minimum 3 m] and must be load
bearing, FAA = 0.33 main-rotor diameter [minimum 6 m],
need not be load bearing (downwash only).
safety barrier Emergency arresting barrier across carrier
flight deck (US often barricade net).
safety belt For passenger, normally called seat belt or
lap strap; for flight (occasional cabin) crew, seat harness.
Safetycom Radio frequency [135.475 MHz] where no
specific v.h.f. frequency is notified [CAA, from Nov. 2004]
(UK).
safety disc Disc of accurately known strength sealing
fluid system, eg cartridge-operated, serving as safety
valve.
safety equipment Vast range of personal items, of which
the most obvious is a parachute, others being helmet,
goggles, armour, whistle, dinghy (with fluorescein dye),
Sarbe (or similar) beacon, torch, mirror, pocket GPS,
Very pistol and in some circumstances anti-NW flash
protection or a handgun. Does not include normal flying
clothing, oxygen mask or microphone, but does also
include aircraft equipment, such as seat harness, axe, fire
extinguisher and escape slide.
safety equippers Specialized ground staff charged with
maintenance of safety equipment.
safety factor See factor of safety.
safety harness Ambiguous, see safety belt, seat harness.
safety height Not accepted term (see DH, MDA, etc).
One authority: lowest at which safe to fly on instruments.
safety imagination Ability to extrapolate from a real
near-accident to hypothetical accident.
safetying 1 Rendering explosive or pyrotechnic device
safe by positive means. See safing.
2 Installing locking wire or other device which prevents
an attachment from becoming loose.
safety net One designed to catch flying object with
minimal damage, eg ejection seat on test model in tunnel
(esp. spinning tunnel) or flying rotor blade in rotor test rig.
safety pilot One present in cockpit to prevent accident,
eg to radio-controlled aircraft or RPV, or with pupil on
instrument practice.
safety pins Those inserted to disarm ejection seat except
in flight.
safety plug Blow-out plug serving as safety valve in case
of excess pressure (eg JATO bottle) or excess temperature
(eg tyre after prolonged braking).
safety speed That above which aircraft is safe to fly with
given load and configuration; formerly several, eg FUSS,
but most important today is V 2 .
safety thread That connecting D-ring (ripcord) to parachute
pack.
safety wire Locking wire passed through holes in nuts,
turnbuckle barrels and other fasteners in such a way that
they cannot loosen subsequently.
safety zone Area reserved for non-combat operations by
friendly forces (DoD).
