Gentlemen,
I am thinking of putting a D180 in my currently under-construction RV9. Will interface it with a Garmin 430W. Going with the 180 for two reasons (1) space and (2) cost. Problem is this--when on an IFR approach I will need to have 1/3 of the screen devoted to my HSI/LOC/GS, thus precluding use of any EMS functions while flying the approach (unless, of course, I toggle the display a whole lot--not something I really want to do.)
During the 10 or so minutes I MUST concentrate only on the LOC/GS on that 1/3 of the screen, I will NOT be able, of course, to monitor RPM's. Let's faced it, with fuel injection RPM's are not crucial to monitor, but I would call such monitoring "highly recommended."
All that being said, can I provide input from the engine relative to RPM's on both the D180 AND an external tach? I can forego all other instruments during a brief instrument approach, but really need a tach PLUS the LOC/GS.
Thanks,
HUGO
