OK... Piper Warrior...PA28-151

Considering purchase...

It's is a 1976 Model..

Specs, (published) say stall, dirty ( Full Flaps ) for a 1976
built is 58 knts.

...1977 and later is 44 knts!

WHAT changes were made to bring the stall speed down by 14
knts!


Are you sure the units are the same? Older birds used MPH.

Vaughn



I'll bet Vaughn is right on this one. My '63 Cherokee 180 POH is all
MPG instead of KPH. I thought that most companies had switched
totally to KPH by about 1970, but I recently checked out in a '76
Arrow and the POH on it was also full of MPG instead of KPH.

Check with that owner to see if he was quoting knots or statute MPH.
Because those numbers do sound high. My Cherokee 180 POH quotes 57 as
the "Stalling Speed (flaps down, MPH). 57MPG is just under 50 KPH --
about 49 knots. That would be a little more reasonable for a Warrior,
which is very similar in design to a Cherokee.

Oh, and remember -- there are things that can be done to modify those
stall speed numbers. Putting on newer design "Horner" style wing tips
and stabilator tips will drop stall speed about three to five MPH.
Vortex generators on the wing top just behind the leading edge can
drop stall another MPH or two. Flap & aileron seals can make a
difference. Fairings on the flap extension actuators help. Wing root
seals/fairings help. Wheel pants are a BIG help. Etc...

From my reading, you can actually get your stall speed down almost
10MPH by putting on every gizmo kit STC'ed for a Warrior. And at the
same time, you'll be adding top end speed to the plane as you smooth
out the airflow. Problem is -- you'll spend a fortune doing it !!!
