ammunition
ammunition Projectiles and propellants for guns;
increasingly, guided weapons are logistically treated as *
but term normally excludes them.
––––
P
ammunition quality Coefficient of, symbol r, = m w
where P is hit probability of each shot, m is mass of projectile
and W is required average hits for kill.
ammunition tank Compartment or container housing
ammunition for airborne automatic weapon, usually in
form of belt arranged in specified way; reloadable, usually
when removed from aircraft.

ampere SI unit of electric current (quantity per unit
time), symbol A; named for A.M. Ampère but no accent
in unit except in F. Hence: ampere-hour (1 A flowing for
1 h); ampere-turn (unit magnetising force, 1 A flowing
round 1 turn of coil).
AMPG, a.m.p.g. Air-miles per gallon, air distance flown
per gallon of fuel consumed. UK gallon was Imp; distance
AMS
was statute miles (not “air miles”). In US, st. mi. and US
gal (0.83267 Imp gal). New unit must be found; SI
suggests air metres per litre, unless fuel measured by mass
(see AMPP, NAMP).
amphibian Aerodyne capable of routinely operating
from land or water. In US occasionally amphibion.
amplidyne D.c. generator whose output voltage
governed by field excitation; formerly used as power
amplifier in airborne systems.
amplification factor In thermionic valve (radio vacuum
tube), ratio of change in plate voltage to change in grid
voltage for constant plate current (UK, plate = anode).
amplifier Device for magnifying physical or mechanical
effect, esp. electronic circuit designed to produce magnified
image of weak input signal whilst retaining exact
waveform.
amplitude 1 Maximum value of displacement of oscillating
or otherwise periodic phenomenon about neutral or
reference position.
2 Angular distance along celestial horizon from prime
vertical (ie due N–S) of heavenly body, generally as it rises
or sets at horizon.
amplitude modulation MCW or A 2 emission in which AF
is impressed on carrier by varying carrier amplitude at rate
depending on frequency, and depth of modulation
depending on audio amplitude.
amplitude modulation equipment [or equivalent] Processes
info. and carrier separately and reconstructs them
to make equivalent AM signal.
