I have a few ideas, and if wrong a few questions =80

Other ideas:

• 1.=C2 Even though you dismissed weight, I wonder if there is=something about the weight that alters the optimal fuel burn ration during=takeoff when thrust is highest that hinders range down line?=/p>

• 2.=C2 Does the pain alter the high lift devices such that ta=eoff and landing are less fuel efficient?

Observations:

• 1.=C2 I've never seen a commercial jet painted black=E2 I wonder if the problem is the color or the application/variant y=u used

• 2.=C2 Supersonic jets (no need for Bernoulli) are black all =he time (though this may have more to do with anti-radar) and/or they may =e willing to give up range in exchange for these

chttp://www.merriam-web=ter.com/dictionary/gedankenexperiment> except dominated one 3.=C2 is by pained rolling I was black. resistance trying Would to do and a the form Gedankenexperiment same drag, range-reduction while to simplify subsonic the effect pla=es problem: be are =bserved? imagine dominated If two not, by fast would skin cars, friction? it identical be because Or would in every=way, cars the are

effect be absent because t=e speeds are too low?

Lastly, a question:

1

When you "undid" this black paint th=ng, did you strip off the black paint, or did you just re-paint? If the la=ter, did you recoup the lost range?

i did not repaint ANS, =C2 fuel expands when heated, . so though the plane intially=took the same amount of fuel the black wings heated the fuel and thr=w it overboard.!!!
