Classroom. Class sizes for small ASTC's are 6 to 8 students per
day, with a staff of 8 to 10 personnel; medium sized units have 12 to 14
students per day and a staff of 10 to 12 personnel; large units have
approximately 36 students daily and a staff of 18 to 22. Groups outside the
building occasionally use the classrooms. Accommodate any special needs
cited by the Officer-in-Charge. 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. Fixed seating tiers can decrease
flexibility. Use of maps and fold out materials by trainees may require
seating at tables.
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. 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.
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. Consider the following major factors for
design of classrooms:
1)
Seating types and arrangements and writing surfaces
2)
Space and furnishings for the lecturer
3)
The use of wall space, including teaching aids and windows
4)
Projection and TV facilities
5)
Coat racks, storage and other conveniences
6)
Acoustics and lighting
7)
Heating, ventilating and air conditioning
8)
Aesthetic considerations
Provide acoustically rated accordion folding panel partitions with
integral door where flexibility is desirable for subdividing classrooms.
Extend details above finished ceiling to assure integrity of specified sound
transmission class (STC) in the interstitial space.
Portions of survival training involve hands-on mockups and display
of survival gear. TV monitors and special projection systems in addition to
traditional marker boards or porcelain boards may be used. Refer to
