probably destroyed Assessment on enemy aircraft seen
to break off combat in circumstances which lead to
conclusion it must be a loss, though not actually seen to
crash (DoD, NATO).

PROC 1 Procedure.
2 Procurement.
procedure alpha Ceremonial manning of flight deck of
carrier, eg when entering harbour, often with crew
arranged to spell vessel’s name or a slogan.
procedure manoeuvre Accurately flown and/or timed
flight manoeuvre for identifying or ATC purpose.
procedure turn Flight manoeuvre in which turn is made
at constant rate away from track followed by constantrate
turn in opposite direction to enable aircraft to capture
and hold reciprocal; precision manoeuvre used in radio
range, holding over point fix prior to joining stack, joining
ILS wtihout radar vectoring, or in simulator training of
traditional (Link) type. Designated left or right depending
on first turn direction.

critical temperature followed by cooling in air or other
medium.
