Glide range ring on MFD?

[mraviator]

On the attached screenshot, is the blue circle on the MFD an engine out glide range ring? If so, it's incorrect with the given wind, as the wind component is visible on the PDF and a longer glide range should occur to the 10 o'clock direction on the MFD.

bu tit's possible I'm misunderstanding what that ring is.

Hi,

glide range would be phenomenal, over 75nm :))) but it isn´t.

It´s the available flight range based on calculation of speed over ground, fuel consumption and fuel volume in the tanks.

Thought those rings were green and green checkered?

He's got more than two hours of fuel left at current consumption, and rocketing along at M054, a distance of less than 100nm means it's 100% for sure not a fuel endurance range.

I agree,

i had a close look at the navigraph charts: it might be a reserved airspace ??

Would match from the color of the ring, but not the same position... maype a temporary restriction (i used airac 1811)
