<DIV><FONT face=Arial>With the P & W R-2800, T.O was with the cowl
flaps in the 4 degree position- actually, in trail. These were gradually
set to keep the heads at a certain temp. for cruise. Actually, they were
closed, which gave much LESS of an exhaust opening, than the cowl intake.
As I recall, the Wright R-3350 was about the same. BTW: With the cowl
flaps in the full open, (ground) position, some airplanes wouldn't stay in the
air, due to drag. A Boeing 377 was put into SFO Bay one time when the
engineer accidentally turned the cowl flap control knobs in the wrong direction,
fully opening the cowl flaps. I don't believe anyone lost their
life. </FONT></DIV>

<DIV><FONT face=Arial size=2> I think the rule of
thumb...... exhaust should be 4 times the area of the intake. That
also depends on the oat(temp) you fly in.</FONT></DIV>
