    So I'm mid-flight from KMIA to KDFW, up against a 90kt headwind. As I'm scrolling through the FMS Progress pages, I see what appears to be an error in the TAS reading. It's showing 221kts, when I'm at FL300 and 250 KIAS. Littlenavmap indicates a groundspeed of 312kts. A TAS calculator indicates that I should be seeing about 416kts in these conditions.
    I've attached a screenshot that tries to capture everything in one view. Is this an error, or am I doing something wrong? Cheers all.
