Next Question: What's this?

[Tom Seeley]

This is a symbol that was never on the approach plates when I earned my living flying. For reference, this one is on the VOR/DME-B Approach for Salmon, ID (KSMN).

Anyone know? (This was established by the FAA in October of last year)

It's a cold temperature restricted airport and indicates a cold temperature altitude correction is required on this approach when the reported temperature is at or below that temperature.

Yep. Pretty involved complex process for a pilot.

So here's my follow-on question....  And I ask because I couldn't find it but then again that's maybe because I scanned too quickly, I'm still in the lovely fog of Caribbean vacation, or both....  On the table on page 4-GEN-15, are those temperatures in C or F?

[Tom Seeley]

Celsius. AIM 7-2-3

The chart in the 4-GEN-14 left out the legend along the left side.

Cool, thanks.
