KC-135 Boom Operator Partial Task Trainers
(BOPTT)
Project Overview: The
US Air Force uses only two KC-135 boom operator trainers
to support all their boom operators. Originally developed
in 1978, these two trainers received a visual system upgrade
in 1990. Even with this system upgrade, the aged technology
impacted the trainers' effectiveness and reliability. In
addition, one of the two trainers was out of service due
to a combination of outdated technology, unreliable performance,
and age. These circumstances put a tremendous amount of pressure
on the fragile, remaining trainer supporting the Air Force’s
entire worldwide boom operator training needs. ACME’s
upgrade gave new life to these legacy trainers.

Upgrade Details: ACME
accomplished a supportability upgrade to the two trainers that
increased reliability and sustainability while also increasing
training realism. The modification incorporated cutting-edge
image generation and control loading technologies into the
existing BOT structure.
The modification also featured:
- Replacing the existing Encore host
computer, then re-hosting the trainer aerodynamic code on
a new PC-based host computer
- Developing a new graphical user interfaced
instructor operator station
- Replacing the single channel visual
system with a new PC-based image generator and rear projection
screen display system
- Developing a two channel, electric
control loading system to provide force feedback for the
ruddevator (boom control stick)
- Replacing the aural cueing system
and installing a digital intercom system that matches the
aircraft configuration
- Completely refurbishing the student
station while simultaneously replacing all trainer instrumentation,
signal input/outputs (I/O), wiring, and cabling
The trainer revitalization followed
the USAF goal to optimize training efforts that produce highly
skilled operators, a priceless force multiplier in this era
of limited resources and extensive weapon system life extensions.
ACME Services Used: Mechanical
Engineering, Software Engineering, Systems Engineering, Web
Design Analysis Consulting, Fabrication, Technical Documentation,
Technical Teams.
