by "- Continued" (see Figure 2). If crowding will occur the "- Continued" may be placed on the following
line (i.e., assuming that the last code of the preceding page is 11AAA Aileron Actuator:
11000
AIRFRAME
System
11AA0
OUTER PANEL -
Second Level Assembly
Continued
11AAB
Aileron Follow-up Cable Third Level Assembly)
Guide
Electronic Presentation: Data shall be formatted as a scrolling table viewable by WUC.
3.2.15.1 Work unit code column heading. The irst line entry at the top of each WUC column shall be the
