You guys are focusing on only one of many many features of the VP-200. There is a reason why those of us with this device are loathe to give it up - you get a lot more than simple circuit protection:
1. Alarm trip points for under-voltage (with and without engine running)
2. Alternator - support for dual, internally or externally regulated (including B&C SD-8)
3. Annunciator light circuits (for master warning)
4. Auto Boost (turns on boost pump if fuel pressure drops)
5. Auto-pilot disconnect warning (senses when autopilot turns off)
6. Aux battery voltage display
7. Battery contactor failure alarm
8. Canopy lock/unlock using remote control (uses standard remote logic)
9. Canopy seal inflation/deflation system for Lancair (w/annunciator)
10. Checklists, display automatically on Mode change
11. Codes required to start engine and to enter setup menus (replaces need for key)
12. Co-pilot trim and flap switches disabled using soft keys
13. Electrical system and status graphical display, including real time current draw for overall system and per circuit
14. Endurance bus circuitry (backup power)
15. Endurance bus failure alarm
16. Engine and Flight timer
17. Engine data logging
18. Engine gauges configurable based on Mode
19. Engine gauges with visual and audio alerts for exceedences
20. Engine leaning functions
21. Engine RPM drop during mag check process displayed
22. Engine run-up bug on RPM gauge displayed at correct time
23. Flap actuation user-configurable (intermediate settings)
24. Flap and trim position display
25. Flap control with electronic motor braking
26. Flap over-speed warning (user configurable)
27. Flap switch disabled above specified airspeed
28. Fuel tank level display
29. Landing gear circuit can be disabled while on ground
30. Landing gear up audio & visual warning on landing
31. Landing gear up, down, and in-transition indicators
32. Landing light pulse (wig-wag) tied to aircraft speed
33. Listing of status (on, off, fault) of each electrical device
34. Mag switch with audio and visual alarms for incorrect position during start, takeoff, cruise, landing and shutdown
35. Manual switching of electrical devices
36. Master switch, with timed automatic shut off in Pre-Flight Mode and Post-Flight Mode
37. Mode determination (pre-flight, before start, start, after start, taxi, run-up, take off, cruise, maneuver, landing) with automatic and manual sequencing
38. Mode-based automatic device switching (on/off)
39. One +12v regulated power output circuit (3A capacity)
40. Over-current protection for each circuit (fully configurable)
41. Over-voltage alerts, protection and automatic shut-off of alternator(s)
42. Remote control with four user-configurable buttons (encrypted)
43. Solid-state short circuit protection
44. Starter switch based on soft key
45. Status indicators for GPS and engine data inputs
46. Switch inputs - user-configurable remote (for flap, trim switches)
47. Switches ? 3 manual with LED status indication
48. Taxi and landing light soft start
49. Trim control with runaway trim protection & backup trim switches
50. Trim motor output +12v regulated
51. Trim motor variable speed to reduce trim sensitivity above specified speed
52. Under-voltage alarm
53. User definable annunciators triggered by discrete inputs (door, canopy, etc)
54. User re-settable circuit protection
55. User-activated Emergency processes and checklists
56. VMC and IMC user-configurable load-shedding
57. VMC/IMC switch controls devices on/off
I certainly don't use them all (landing gear up - what is that for?
) but I sure use a lot of them.
