Why Not Two Waypoints?
I have a question that people have been asking me and I don’t know the answer.
Readback: March 2010
I have a question that people have been asking me and I dont know the answer.The G1000 has two GPS receivers: GPS 1 is the default choice and automatically switches to GPS 2 if there is a problem. Or you can manually select GPS 2.My question is: Why can only one be used at a time? For example, one GPS could be the primary navigator with the flight plan and the other could indicate final destination or a waypoint on the side of the track or even an alternate.
Key Takeaways:
- The article critiques limitations in aviation avionics, such as the G1000's inability to use dual GPS receivers simultaneously for multiple waypoints and the omission of VOR frequencies on GPS approach plates, suggesting manufacturer programming priorities as a cause.
- It clarifies specific IFR currency requirements under FAR 61.57(c)(4), stating that combining aircraft and ATD/simulator time for currency requires one hour in the aircraft and three hours in a simulation device.
- Critical pilot safety reminders include that "radar contact" does not assure terrain clearance, and while unmonitored approaches cannot be *filed* as alternates due to TERPS requirements, they can still be used as real-world alternates if needed.
