There are a number of advantages in using the semimonocoque fuselage. !    The bulkhead, frames, stringers, and longerons aid in the design and construction of a streamlined fuselage. They add to the strength and rigidity of the structure. !    The main advantage of the semimonocoque construction is that it depends on many structural members for strength and rigidity. Because of its stressed skin construction, a semimonocoque fuselage can withstand damage and still be strong enough to hold together. Points on the fuselage are located by station numbers. Station 0 is usually located at or near the nose of the aircraft. The other stations are located at measured distances (in inches) aft of station 0. A typical station diagram is shown in figure 4-7. On this particular aircraft, fuselage station (FS) 0 is located 93.0 inches forward of the nose. 4-7 400 380 360 340 320 300 280 260 240 220 200 180 160 140 120 100 80 60 40 20 0 20 40 60 80 100 120 140 160 180 200 220 240 260 280 300 320 340 360 380 400 0 50 100 150 200 250 300 350 400 450 500 550 600 650 700 750 800 850 ARRESTING HOOK FULLY EXTENDED STATIC GROUND LINE FS - FUSELAGE STATION WS - WING STATION ANfO407 AIRCRAFT STATIONS WS 20 WING UNSWEPT o 68 WING SWEPT o 75 WING OVERSWEPT o Figure 4-7.—Fuselage station diagram of an F-14 aircraft.
