Shocking. Time to upgrade. Minimum equipment:

PowerFlarm
Logger#2
AHRS w/GPS
Personal tracker
406ELT w/GPS
iPhone w/GPS

Obviously you're way behind!
And probably not enough batteries either ;-)

I have 5:

Air Avionics ISU
PowerFlarm
iPhone 6+ used for iGlide
iPhone 5s used for cell phone
Delorme Inreach

Nevertheless, in the unlikely event of an EMP or the more likely event of GPS interference/unavailability, none will work.

But I have never flown a compass course in a glider. In VFR, you don't need it; in IFR, it is insufficient without an AHRS, and then you don't need it. Conclusion: you don't need it.

Jon, thought I had four GPS devices but if you're counting phones, etc....
ClearNav vario
ClearNav 2
Air-Glide vario
PowerFLARM
APRS
InReach
"Phone"

Realised a week or so ago that there is no vario needle in the panel. Just triangles, lines and dots.

But there's a mysterious liquid-filled instrument near the bottom of the panel that has numbers on a wobbly thing inside.
It's not on the minimum equipment list. Should probably be stored somewhere with a sextant and knotted rope or the vacuum tube NAV radio from an Illyushin IL-76.

Did find a magnetic compass in the F-16. All gliders I know of do require a compass so for now I will have one. Tried to get by with a stick on compass that I bought at Auto Zone, but that did not fly (so to speak) with the examiner, so I had to install a glare shield compass.

Let's see now...Hmmm....Forgetting the excellent capabilities of my LX9000, PowerFlarm, and Flarmview, does my Pathfinder watch, which really has an outstanding compass "count?" How about the compass in my Delorme inReach Explorer? It has a digital compass? Now, what year is this? Is it 1947? 1952? Geezzz...Now, please excuse me..I am trying to see if I have room in my glider for my new sextant....(available right now on the Home Shopping Network.....Stock is limited, so do not delay!).... ;-)
