Q4
Monitor Replacement
Projector
Engineers from Q4 successfully installed and
certified the first LCoS MRP system at United
Airlines in Denver, Co.
The Alion
supplied system was
retrofitted to a 747-200 and has provided
uninterrupted training now for some months.
This specification describes the
latest Q4-MRP Raster-Only Monitor Replacement Projector (hereafter referred to
as the Q4-MRP. The Q4-MRP provides a form, fit
and function replacement option for display
solutions that currently use 25 inch
shadow-mask color CRT in wide-angle collimated (WAC)
optical systems as used by XKD and E & S (CSM).
The Q4-MRP
achieves this requirement using fixed matrix
projectors instead of 25-inch direct
view CRTs.
The
Q4-MRP
is designed for
use as a visual simulation display, primarily in
conjunction with WAC optical systems that operate up
to a maximum of 64 kHz line frequencies. It supports
up to nine high-resolution channels with image
matching between adjacent channels. It can achieve
raster distortion necessary to accommodate the
requirements of the infinity optical system, in a
juxtaposed configuration.
The
Q4-MRP
can be operated at either 50
Hz or 60 Hz field/frame rates. The
Q4-MRP
can pre-store adjustments of
geometry, convergence, shading, focus, contrast and
brightness.

Equipment Configuration
The
Q4-MRP
consists of the following major assemblies:
·
Display Head Unit
·
Remote Control Unit (one per system)
·
Interconnect Cables
The JVC model HD-2K DILA projector, incorporating
LCOS technology that produces picture resolution
1920 horizontal pixels by 1080 vertical lines. The
vendor incorporates a custom lens modification to
optimize the performance for simulation application
to match the radius of the applicable back screen.
The HD-2K operates in raster mode with a horizontal
raster and support line rates at 60Hz.
Due to the modular
nature of the
Q4-MRP
it is possible to fit many
different types of projector within the housing.
This provides the end user with a high degree of
flexibility in design to allow for varying
requirements in resolution, cost and brightness.
The housing and components are be designed such
that no observable effects on the picture stability
or presentation due to normal runway rumble, stall
buffet or other vibrations inherent in the motion
systems exist. Maximum motion system acceleration
and deceleration will not damage any of the display
system hardware, nor cause any degradation to
optical or electronic alignments. The overall weight
of the housing and components does not exceed 150
lbs.
Video RGB signals, synchronization signals, and
defocus signal shall be input to the DHU via VGA or
DVI input connections..
A secondary communication port using RS232 protocol
will also be provided for maintenance functions and
host communications of hour meter readings etc...
