| Subject: | Re: Palmer's Glasair |
Actually, it's not mine but a friend's.

Anyway, per the website glasairforsale.freevar.com
It's a Glasair One and One Half. It started out as a Glasair I but has
the new Glasair II fuselage. (Hence the 1 + 1/2 moniker.)
It's has a tricked out narrow deck O-320. 9:1 pistons, 5 angle valve
job, a little bit of polishing and porting, Lightspeed Plasma on one
side. Seems like it makes 170 HP.
$64,500. It's been flying for 17 years and 3250 hours. Just about every
part has been replaced once. (Friction pad on nose gear, long blot and
bushings on upper nose strut attach point, aileron hinge pins, for
example.) You're paying a little extra for a well proven "experimental"
aircraft. Nice to know when you're flying in the junk at night.

I was reading a post about some Glasair owners having trouble
determining an airspeed at which their planes stall. I don't have an
answer as to why this is occurring but I would like to suggest the use
of and angle of attack indicator. Air speed is a result of angle of
attack. Alpha Systems AOA has an angle of attack system that takes
differential air pressure through a probe mounted in an existing
inspection port under the wing, converts that differential air pressure
to an electronic signal through an interface module which is then in
turn displayed on a color indicator(bar graph or chevron style) mounted
on top or under the glare shield or in the instrument panel. The use of
angle of attack is extremely useful since airspeed is often inconsistent
especially at low indicated airspeeds and requires a pilot to calculate
airspeeds mentally as conditions such as density altitude, gross weight,
etc., change. This system calibrates to Optimum Alpha Angle or OAA
which is roughy 1.25-1.3 Vso which is a slow flight airspeed in which a
plane is not climbing nor sinking and has full control surface
authority. Utilizing this system will create a wider safety envelope
for all pilots.
