K 4.2.2.1.3 The Avionics Suite must
enable Aircrew to conduct aided visual
searches in low light conditions down to
2 mlux.
848 K 4.2.2.1.4 The Aircrew must be able to
view any enhanced (through amplified
intensity) external low light images
seen when conducting the aided visual
searches in a monochrome display.
conducive to effective
searching include:
ergonomic seats,
comfortable clothes,
rotatable seats, radios
etc. positioned at search
stations, climate control
etc.
2mlux is taken to be a
near moonless clear
night without cultural
lighting.
Full NVG compatibility of
the avionics suite would
be a minimum prerequisite
to achieving this
capability.
For the purposes of this
requirement, an aided
visual search might
include the use of:Flares
External Lighting
This requirement could
be met through the use
of NVG.
Any aircraft internal
displays used to meet
this requirement e.g.
avionics and FLIR, must
be fully NVG compatible
and not detract from the
use of helmet mounted
NVG.
Oh dear - that doesn't appear to have been met yet or is someone using the 'flares or external lighting' sentence as a get out of jail card?
