Pattern Altitude
I'm aware of RAIM, etc., for panel mounts; was just more interested in whether the Dual was really necessary, or if the iPad GPS receiver was sufficient. In a 172, my Dual goes up on the glare shield, with Bluetooth connectivity to FF/iPad - one reason I bought the Dual, vice Bad Elf - the Dual is out of the way, and can see the sky, more or less unobstructed. In about 8 years of use, I haven't seen any accuracy/position differences between my Dual/iPad/FF combo and the Garmin in the panel. I have lost a Garmin twice (two different models) - once on an ILS, once enroute. The Dual/iPad stayed up, but those were just anecdotal, isolated events. And maybe FF just THOUGHT it was up.
Anyway, my iPad is getting long in the tooth, and I'll replace it soon - curious if the consensus is the iPad GPS is sufficient - not to stir up a ruckus, and not much interested in feedback on the practice, but I mostly use FF/iPad as primary en route, with the panel mount as semi-backup - basically, changes go in FF first, then when established, I do the Garmin knob twisting. Understand YMMV - given that as background, are the GPS receivers in newer iPads solid? Understand it's just opinions and impressions - would like to hear.
My iPad GPS hasn't given me issues thus far but I like my Stratux for WX and traffic in addition to the WAAS GPS...
