Re: Low power cruise in a Cherokee 6

I have very recently purchased a Cherokee 6-260 and was wondering if
anyone has any sugestions regarding the most economical cruise
settings? Speed is not so important as MPG. Most of the distances I
fly are not long, so high altitude stuff doesn't really factor in.
Most flights will be 100 to 300 miles and maybe 5000'. This is a
carburated engine, so GAMI's and lean of peak doesn't fit the picture.
I have heard of lean of peak with a carb and some carb heat, but I
usually fly 60% power at peak as per the Lyc operators manual.

I have been told I can get 11-12 gph at 120 knots, but I seem to use
more fuel. Any suggestions?

Thanks,

John

John,

I looking at a POH from a 1968 PA32-260 and at 7,000 ft density
altitude the cahrts are indicating about 140mph (121 kts) true. The
power settings for 55% power at this altitude are: 20.2/2100,
19.3/2200, 18.3/2300, or 18.0/2400.

Obviously, make sure that you're using true airspeed and not
indicated. Do you have the wheel pants installed? Another huge
problem with getting book speed out of a cherokee is the rigging of
flaps - if you go www.pipermods.com there's a drawing of a tool to
check for proper rigging.
