Wing Extensions

Bob, Bob, Bob,

You can make a AOA indicator for $50 and a little bit of time to machine
a dual purpose pitot - AOA pylon for the end of your wing.

I do agree that many gauges on the dashes of many kitbuilts are
worth a great deal less than the asking price, but a stall warning
system is worth its weight in gold!!! Just ask the gentleman that
"made it" to Oshkosh in a Glasair got stuck behind a cub on final,
did "s" turns until he fell out of the sky 400 ft short of the runway.
DEAD.

Another Information System Engineer, but without a gold lined wallet.

The airpseed indicator could certainly be marked that way
and inspectors may approve it, but it seems like the long-wing version
would be more critical for safety numbers. Vne would likely be lower
for the long wing(*), and maneuvering speed will be lower as well,
assuming the extensions add any lift at all. Stall speed for *both*
wings is important.


Forget "stall speeds." A given airfoil stalls at a given AOA. Period.
Loading, airspeed, aspect ratio have nothing to do with it.

Get an AOA indicator and fly that.

A rather amusing, although assinine approach....
Killing a bug with an extravagant $ledge hammer.

Is this what pompous information system injun-eers
are good at?
