Directed to Descend to an unsafe Altitude

[Arwen 289]

My flight plan was for an IRF flight from KASE to KEGE.  I added a SID: LINDS, with RW33 and SWX VOR as a waypoint.

 

KASA Hdg-343 LINDZ TOD PT SXW KEGE

 

My Cruise Alt was 10000 feet and my Dscnt Rate was 500 EPM (my aircraft was a Cessna 172).

 

I was direct to ascend to 9600 feet (KASA sits at 7620).  When I reached TOD PT, I was directed to descent to 6500 feet, when I proceeded to do, at the rate of 500 FPM. This descent path would have made me hit the mountains to the southwest of SWX, had I not pulled up on my own.

 

Note: I had checked "Calculate Sate Enroute Altitudes" from the config settings.
