Chris,
That is why I made my stall strips, tested them and then painted and remove
d them. It only takes a minute and some tape to put them on but like you a
nd most others, we get used to our aircraft and don't install them as it is
just more testing. I like tinkering and I prefer an airplane with a pre-s
tall rumble warning so I took the time to make them. Other pilots flying w
ith me like the rumble and stall warner combo to use as a point to recover/
slow flight at.
On some Europa's with a forward CG and built light I can do a full aft stic
k (deep) stall without the stall strips but it is rare. With stall strips,
I can coax a full aft stick stall in many of them. But there is no need t
o do a full aft stick stall in reality. It is a confidence maneuver in som
e aircraft to demonstrate coordination, rudder control, and aircraft capabi
lity. There is no need for doing that in a light aircraft, but some Europa
's can do it. There is no need to ever do it beyond flight test again unle
ss trying to ascertain if a damage repair is done acceptably. Other than t
hat...It=92s a Worthless Maneuver which done improperly can result in an ou
t of control situation. Be at least three mistakes high when doing any sta
lls or aggressive maneuvering.
Mostly I like the gentle rumble during a clean hard turn, warning me of too
much pull (AoA) in an airplane. With the stall strips I find N12AY with f
ull flaps doesn't give me 5 knots of pre-stall warning but three with the s
tall strips, and the stall speed is 2 knots faster with plenty of warning.
It also tends to drop the left wing in the fully configured stall unless I
add in a bit more rudder. Without the stall strips the left wing drop is
a little more pronounced but with proper rudder control I can make it bobbl
e up and down somewhat violently as I get to full aft stick in a heavy buff
et (the buffet without the strips is heavy and is a bit scary). With the s
tall strips, it simply rumbles lightly, mushes and has a much less pronounc
ed bobble. With the stall strips, 12AY will break before you can achieve f
ull aft stick. Maybe I'll work on that during this winters annual if I get
bored. Of course, it is not broke, so why fix it.
Best Regards,
Bud Yerly

Bud, I enjoyed your last reply.
I personally don't have stall strips in my airplane. I find it gives plenty
of warning before the stall and it stalls straight but yes, it is not very
tolerant of mis-coordination. I attribute my sensitivity to detecting the
stall to years of flying gliders (often flown at the verge of stall) and fu
ll time CFI duties.
However, I liked your posting because despite me not being very old I am st
arting to get there and you are right on that with age having additional sa
fety measures makes sense.
So yes, I will install stall strips in the future or if one day I consider
selling my Europa (hopefully not in a very long time).
Chris
