Brief Description: Instrument Panel
|
|
It may seem too early for this but I’ve spend some time on the instrument panel for a very good reason; I believe that the selected panel components do dictate what needs to be installed on the plane. Especially when it comes to autopilot stuff, AOA, navigation or else. From what I have seen on the assembly drawings, it looks like the RV-14’s components and related attachments (ADHARS boxes, A/P servos, wire harness, etc) are based around Dynon’s Skyview system. Nothing wrong with Dynon but there is one pitfall for us here in Canada with this choice; the Skyview system relies on third parties for aviation maps to operate. And there is no sign for this to change any soon. Garmin on the other end, proposes maps based on their own database (mostly Jeppesen style), handled through proprietary software which is developed to facilitate the maps update of your own unit. No fiddling with third party application.
In a nutshell, this is why I have made provision for additional grommets in the left wing ribs to allow passage of 3 different ¼ inch plastic hoses for Garmin’s pitot tube (static and AOA). Dynon’s, ADAHRS units are installed on a bracket riveted to the left wingbox structure as opposed to Garmin who tells you to install it in the tail section (in this case behind the baggage compartment bulkhead), on the very center of the fuselage. Garmin’s servos for the autopilot are quite similar to Dynon’s except that they have a “clutch” within the servo that minimizes to nearly nothing the internal friction. Finally, both systems are very comparable from a price standpoint so I’ve elected to go with Garmin.
One note about my panel layout; I’m proposing is to install the larger screen facing the pilot seat and the smaller one on the center. In my opinion, installing a screen facing the co-pilot seat is pure waste because it will be barely usable by the pilot. Besides, knowing that 98% of all the passenger that I’m flying with are pure aviation neophytes, why spend the big $$$ for something useless?

Same as the first one but slightly different switches

Earlier design borrowed from the RV-9. Very expensive
