GENERAL ARRANGEMENT Each wing provides two hard points for external stores pylons with hydraulic and electrical quick-disconnects. Figure 2-1 depicts the general arrangement of the Wing tip pylons are installed on the outboard portion of AH-64E Apache helicopter including access panels and each wing for mounting the ATA launchers. major exterior components. 2-7. SPECIAL MISSION KITS 2-3. FUSELAGE The helicopter can be equipped with the following kits: The fuselage includes a forward, center, and aft section. All major weight items (crew, fuel, and ammunition) are Longbow Fire Control Radar (FCR) supported by bulkheads, frames, and a longitudinal sup- Winterization port structure. Extended Range Fuel System a. The forward fuselage section contains a portion of the Extended Forward Avionics Bays (EFAB), and the ASE CPG station. The TADS, PNVS, and M230E1 AWS are Air to Air to Ground (AAG) also mounted to this section. Upper Receiver (UR) b. The center fuselage contains a portion of the Link 16 EFAB, the pilot station, and provides support for the main landing gear, main transmission, wings, fuel cells, 2-8. PRINCIPLE DIMENSIONS and ammunition bay. Figure 2-2 illustrates principle helicopter dimensions. c. The aft fuselage section includes the vertical sta- bilizer and mounts the tail landing gear. The aft avionics 2-9. TURNING RADIUS AND GROUND bay and stowage compartments are contained in the aft section.

When the cursor is moved in the area of a selectable option (e.g. Bezel button controls) the option will be highlighted to indicate to the crew that the cursor is in a selectable area. This should not be misinterpreted as OIP. In MONO mode, labels which would be dis- played in red or yellow during NIGHT mode continue to be displayed in bold font. (1) Bold Font/Characters. Button labels show bold intensity when the cursor is close enough to the symbol to choose it (Figure 2-20). Upon cursor selection, the bolded item will be chosen.
