15.5.1 Instruments, instrument panels and controls
should be permanently mounted in consoles or other appropriate places
taking into account operation, maintenance and environmental conditions.
However, this should not prevent the use of new control or display
techniques, provided the facilities offered are not inferior to recognized
standards.
15.5.2 All instruments should be logically grouped
according to their functions. In order to reduce to a minimum the
risk of confusion, instruments should not be rationalized by sharing
functions or by interswitching.
15.5.3 Instruments required for use by any member
of the operating crew should be plainly visible and easily read:
15.5.4 Instruments essential for the safe operation
of the craft should be clearly marked with any limitation if this
information is not otherwise clearly presented to the operating crew.
The instrument panels forming the emergency control for the launching
of liferafts and the monitoring of the fire-fighting systems should
be in separate and clearly defined positions within the operating
area.
15.5.5 The instruments and controls should be
provided with means for screening and dimming in order to minimize
glare and reflections and prevent them being obscured by strong light.
15.5.6 The surfaces of console tops and instruments
should have dark glare-free colours.
15.5.7 Instruments and displays, providing visual
information to more than one person, should be located for easy viewing
by all users concurrently. If this is not possible, the instrument
or display should be duplicated.
15.5.8 If considered necessary by the Administration,
the operating compartment should be provided with a suitable table
for chart work. There should be facilities for lighting the chart.
Chart table lighting should be screened.
