Pre-takeoff checklist
I have an older WAAS enabled Garmin 430 in my plane. I also have an Android tablet running FlightPro. They both require database updates for the moving map displays. Both are usually running in the cockpit and I've never seen a hint of discrepancy between the outputs regarding position, altitude or any other navigational information. I assume the raw data for their databases comes from the same FAA source in both cases. So, why does the Jepp Direct update for the Garmin cost $425/year for the continental US, while the updates for the tablet app only costs $72/year and includes Canada? Is Jepp Direct ripping me off, or am I just getting a phenomenal deal from my tablet App provider? What about update costs for navigational systems in LSA aircraft, do they fall somewhere in between the costs for a TSO'd system and a tablet? How about the systems for homebuilts? I'm considering my long range purchasing options as I segue into retirement and the bill for the Garmin data is looking hard to justify.
