warrior stall speeds (VSO)

Some references list the VSO (40° flaps) for a PA28-161 at 44Kt, others list
it at 33Kt.That's a pretty big difference. The POH for the one I'm flying says
33Kt. I have a hard time trusting this - Anyone here regularly land their
Warrior at 40 KT (1.2VSO)?

Indicated or calibrated? That might account for the difference in your
references.

I assume you mean "approach at 40 knots", not "land" (the landing would be
done just above stall speed). What does the POH say about short field
landings? I would use whatever approach speed the POH suggests.

When calculating approach speeds, you need to make sure that you start
with the calibrated airspeed. After multiplying by 1.2, adjust back
to indicated.

The 33 knots, if correct at all, must surely be indicated.

Geesus. How many politicians can dance on the head of a pin while
speaking the truth?

None.

Take the airplane to altitude and test it out in a landing
configuration.

Why become a test pilot - if you aren't comfortable stalling an
airplane at 33 knots - then take an instructor with you.

The slowest I ever flew an airplane was 172N at 40 knots with 40
degrees of flaps. I believe the 172N also says 33 and the airspeed
indicator shows the same. I'm not trying it out.

My PA28-180 poweroff stall @ 40deg flaps is 57mph or 49kts.

Granted the Warrior is lighter (and since it is a -161) has a
different wing, but 33kts is really slow.

I think the only way a Warrior might fly @ 33kts, is a full-power
departure stall with 40deg of flaps. And even then, the 33kts would
be indicated, not calibrated.

Piper Warrior II Vso = 44KIAS @ Gross Weight (PIM & Checkmate). 44KIAS looks
to be about 50 KCAS in the IM I have.
33KIAS seems very very slow for a Warrior.

Emphasis on max gross weight. You can beat that figure by quite a bit in a
plane closer to empty.

I love slow flight/MCA. At 2000 lbs gross I've had my Warrior II at 35 KIAS
with full flaps (40 degrees). It was still controllable and would execute VERY
shallow turns. Density altitude was 3100 feet. My IAS/CAS chart in the POH
doesn't go below 45 KIAS and it curves so it's hard to extrapolate.

Here's a chart. Data collected at 2000 lbs gross and 3100' DA:

Flaps 0 10 25 40
KIAS 44 41 38 35
