  1. TH-67 RMI Program KI 825 EHSI Installation ADVANCED DIVISION MOI/QC URS

  2. Purpose/Overview Update on Reliability and Maintainability Improvement (RMI) Program EHSI Cockpit differences Switchology & Displays GPS/VLOC EHSI Standardization EHSI Additional Display modes

  3. RMI Program • Major Overhaul of Airframe and Flight Controls • Structural Reinforcements and Upgrades • Complete Airframe Rewire w/ Single Point Ground • Install Aluminum Pitot Static System • Airframe Corrosion Inspection, Strip & Paint • Obsolete Structure removals • Avionics Upgrades For Maintainability: • KI- 825 EHSI • KX-165A, VHF • KTR-909B, UHF w/ Shock Mounted X-Receiver • GNS-430W, GPS • Airframe Upgrades: • LED Lighting System – Landing/Searchlight STC in work • AFS Inlet Barrier Filters • Dart Skids • Seat Cushion Upgrade- • STC in work • Standby Generator Upgrade (IFR) STC in work • Thixosyn- Main & T/R Hub Lubricant • Windshield Install w/Screws STC Approved • Install DSU Appareo • ALERTS system in remainder of fleet - Pending

  4. EHSI Cockpit Differences

  5. Switchology GPS/VLOC Pressing GNS 430 CDI selector one time switches GNS 430, Right HSI, and both RMI NAV Single Bar Pointers between GPS and VLOC mode with appropriate mode indicated on GNS 430 display and Remote Enunciator Panel.

  6. Switchology: Left HSI GPS to VOR • Left HSI: Switched with MENU selector

  7. Switchology: Left HSI GPS to VOR • Left HSI: Turn right knob to VOR, then press MENU to select

  8. Switchology: Left HSI GPS to VOR • Left HSI: NAV-2 VOR now displayed Notice CDI and HDG BUG digital display in upper left corner

  9. GPS Display Color • BLUE (cyan) when in non-approach phase

  10. GPS Display Color • Green when in approach phase Notice DIST to WPT and GS/TTS digital display in upper right corner

  11. GPS DTK Sequencing • GPS CRS automatically displays/sequences DTK • No need to use HSI Knob to change x-ing WPTs

  12. Switchology: GPS OBS Mode • OBS CRS set through Right-Knob Vs HSI Knob

  13. LOC (ILS) Display: Centered • Glide Slope displayed only on right side of HSI “LOC” displayed For LOC or ILS

  14. LOC Display: Half-Scale

  15. Switchology: Shortcuts • MENU Button: • Press and hold for 2-sec to permit brightness adjustment. • Sync HDG BUG-Press to enter menu mode, press again to • exit and hold 1-sec. HDG BUG will sync to current hdg.

  16. Standardization • For IERW training, only use normal HSI mode to keep it the same as the “old” HSI (will have a mixed fleet!) • All other FTG standards remain the same.

  17. Display Menu Options

  18. Additional Display Modes: 360 MAP mode

  19. Additional Display Modes: ARC MAP mode

  20. Additional Display Modes: ARC/360 MAP mode RNG

  21. Observations • Easy to set manual CRS wrong, double-check student • If you can’t resist, experiment with your own HSI. Don’t play with student’s HSI! • When more of a mixed fleet exists, students will likely forget to manually set GPS CRS with “old” HSI • HFS update being coordinated
