Electronic Maintenance and Repair. Minor repair of the trainer
components is undertaken here by the device contractor. Provide workbenches
for minor repair. Include these on the Collateral Equipment List. Consider
peg mounting boards on the wall for hanging cables. The standard Navy
electronic workbench, type NEB-2 with PS-1A 24VDC electric-converter is
recommended for electronic maintenance shops. Verify if 400 Hz and other
power characteristics are required. Workbenches may be ordered through the
Aviation Supply Office, Philadelphia, PA. Typical installation consists of
three 24-inch wide modules with back panels for an assembled size of 72
inches wide by 33-7/8 inches deep by 60-1/4 inches high. Suggested

General Academic Classroom. Seating arrangement is the most
important factor in determining the size and shape of a classroom.
Accommodate any special requirements for static and operative displays and
team teaching, such as small, medium, and/or large class seating arrangement
flexibility within the same classroom boundaries. The length required for
the front marker board also affects the shape and orientation of the room.
Refer to Timesaver Standards for Building Types, 2nd Edition, (McGraw-Hill
Book Company) for detailed data on seating arrangements. Optimize the
classroom sizes and shapes for flexibility and enhancement of instruction.
Avoid "pie shape" and other configurations which limit alternate seating
arrangements. Determine seating types and audiovisual characteristics before
finalizing configuration. Fixed seating tiers can decrease flexibility.
Consider fixed seating and tiers only in facilities with a minimum of three
classrooms. Use of maps and fold out materials by trainees may require
seating at tables.
Aviation training facilities typically use training devices
requiring mechanical systems support. Consequently, classrooms are often
exposed to a variety of support equipment noises in addition to HVAC unit
noise which can distract from instruction. Provide sound baffles, absorbent
materials at noise sources, and locate mechanical units remote from
classrooms. Avoid sound masking in classrooms. Acoustic design level for
classrooms should be RC-30 with 50 STC (minimum) walls. Provide sound
absorbing materials in lecture rooms to limit reverberation time to 1.0
second, and provide sound-reflecting surfaces on the forward ceiling and wall
surfaces for sound reinforcement. Since classrooms are repetitive spaces,
intense effort is required to assure quality in each duplicated space.
Consider the following major factors for design of classrooms:
1)
Seating types and arrangements and writing surfaces
2)
Space and furnishings for the lecturer
