Anyone know what this yellow ring on the 750 means? The only reference in the manual I could find was a TFR, but it also seems to include a time-indicator. Maybe the TFR starts in one minute? Any ideas?

The yellow is a heads up on a future TFR. You have to check the time it turns red, then active.

Nope - That is a fuel range ring. The time (0+01) indicates that @malcoholio is about to run out of fuel!

Or, that he didn't enter fuel on board when he started.

Here's the relevant manual section:

You’re not really expecting someone to look things up in the manual, are you? It’s just something to throw in the back seat pocket to satisfy the rules, isn’t it?

No, it's hard to find stuff sometimes. Search the manual for "yellow ring".

So I'm not expecting someone to look things up, I'm expecting them to have ME look it up. :rofl:

I wouldn’t. I would search for the whole word “ring.” Someone really smart, maybe “range ring,”

Yellow? This is the company that brought us “cyan.” ’Who knows if they call it “yellow” or “goldenrod.”

Cyan has been a color for a lot of years. Also magenta. They are primary colors for printing ink. Yellow, Cyan, and Magenta.

Take a look at a color printer, it has cartridges for Black, Yellow, CYAN, and MAGENTA.
