I won't discourage you - but If he's close enough to hear,
he's pretty darn close. He's also likely to be wings level
and cruising, so by throwing your wing up, you are probably
increasing your relative impact cross section, which is
usually minimum when the wings are parallel and the paths
are parallel. It's not clear to me that I have enough time
to turn, spot the danger, and then maneuver to avoid. I may
be just turning into him. I have to admit I hate it when I
can hear a powerplane in cruise, but can't see it. What do
others do?


Actually, if you hear an airplane engine, it's likely that it is directly
below you where the sound can reflect back from the ground.

A pilot once told me a story about having cheated on cloud clearance to get
above the bases of a broken cumulus deck. Suddenly, he heard a large number
of big piston engines nearby. Looking in all directions, he couldn't locate
the source of the sound, but it seemed as if a large formation of
multi-engine aircraft would burst out of the clouds at any moment.

This went on for several minutes and he became more and more panicked and
confused since the aircraft making the sound should have passed by.
Finally, a break in the clouds allowed him to see an unlimited hydroplane
race underway on a lake below. Those hydroplanes were powered by V12
aircraft engines.

I'll now tell my near miss story.

Thermalling near Riverside California one day I say a small puff of smoke
off to the south. "That's strange", I thought as I continued to circle.
Next time around the ball of smoke was still there and it seemed bigger.
Several more turns in the thermal and the ball of smoke was getting very pro
minent and there was a black dot in the center of it.

The smoke was jet exhaust and the black dot turned out to be a B52 with me
in his crosshairs. As I dove for clearance, he passed less than 100 feet
above me. That was noisy.
