Howard Marine Porter

Thanks everyone for your help :) I know have a much more knowable mind about the speed situations in an aircraft when cruising at different levels of altitude. Many Thanks Howard

I'm not trying to get rude,i was only saying thanks for the help as i'm new to the pmdg md11 recently purchasing it last week. Do you mean the term used by myself (Thanks alot pal) is on the otherhand rude if so i didn't mean it that way.

Thanks a lot pal your a hero,your help has made an incredible advance with my flying the pmdg md11,fast response.Here's a picture of what i mean.

I'm cruising at an altitude of Flight Level 310 and a speed of 290 knots given by the fms this can't be right as the speed should be 400+ knots.Any help thanks.Ive looked on plane finder via app for ipod touch and seen md-11's cruising at a speed of 450 knots. Please Help! Thanks
