The experience raised my priority for the Angle of Attack installation.
Jim... what's a retrofit like and where do you put the ports?<
Another note about stalls is that the stall recovery looks completely
different when done at high altitude as required by FAR versus at pattern
altitude. I'm not suggesting that stalls be practiced at pattern altitude. I have spent much of the past 5 years encouraging sport aviators to install
some type of stall warning on their experimentals. Part 23 requires a
stall warning on all certified aircraft. The ultimate stall warner is an
AOA and cost as little as $890 (see www.angle-of-attack.com). The ports
are installed between 15% and 40% of the chord and usually ahead of the
ailerons. There are many stall warning devices available from many
sources.
At the risk of sounding like a commercial, I will again be giving forums at
Sun'n Fun, Oshkosh and the NW EAA airshows about "Flying Safe with AOA". We discuss why you can stall your experimental at any IAS, what causes your
Lancair's stall speeds to vary, and why stall warner/AOAs save lives.
When asked, "What does your airplane stall at?", we should all answer, "It
depends!" Once this concept is understood, the importance of stall
warner/AOA becomes obvious. And if you don't stall, you can't spin. Jim Frantz
