Cessna 172 Sink Rate? Ft/minute

[CanucksUnlimited]

Long week in the hangar and we fired up our panel for the first time - Maybe I'm just dead tired, but I can't seem to find the Sink Rate in Ft/minute to input into the computer. Anyone have a clue to throw out? I'll get to the math on Monday.

Picture is from a 'test fit' we did to power on for the first time - no hiccups at all.

Glide Ring Setup perhaps.
SkyView HDX, can display a Glide Ring . For instructions on how to use the Glide Ring feature, see the SkyView HDX Pilot’s User Guide.
There are two (2) settings that need to be adjusted for your specific aircraft for Glide Ring to be accurately displayed:
• SETUP MENU > AIRCRAFT INFORMATION > SINK RATE DURING GLIDE
• SETUP MENU > PFD SETUP > AIRSPEED LIMITATIONS > Vg – BEST GLIDE
