The 1976 Standard Atmosphere data you have is inaccurate, infact it's almost 30 years old. And if that isn't good enough, i have data that's over 300 years old stating the world is flat.
How can the winds aloft be -200knts??? Rather to say from 0 to 200knts would be more accurate. However not a big deal, i think we all know what you mean... of course unless you've experinced a -200knt wind.
You are correct on the denisty alt, the air is thinner, creating problems for aircraft to reach that height. However a 240knt airspeed should be too diffcult to achieve, If my ground airspeed is 175knts, plus a head wind of 75knts, then my ASI would be 250knts. There is a downside to this... it only applies in a headwind.
thank you for the correction.
