Dave: The reason for an AOA indicator and for an aural warning is illustrated by the following quote:
"To answer this question, I launched an investigation of spin accidents, beginning with 1994. I chose 1994 as a starting point because the FAA modified stall and spin training requirements in 1993, and I wanted to see if the changes made any difference in the accident record. In addition, accident reports from 1994 on are fairly easy to access, while those in preceding years become more difficult.
There were 11,302 general aviation airplane accidents in the period I studied, 1994 through 2000. When you consider that it requires injuries or Â“substantial damageÂ” for the NTSB to classify an unfortunate event as an official accident, well, thatÂ’s a lot of bent airplanes.
During this seven-year period, there were 394 spin accidents on record, or roughly 3.5 percent of the total accidents. Earlier research papers on the topic show that the percentage of spin accidents has certainly subsided from several decades ago.
There were 2,288 fatal accidents in the general aviation airplane population in the timeframe of this study. Of these, 324 (roughly 14 percent) were caused by spins. Again, this is down from earlier years. This is relatively good news.
With 324 of the 394 spin accidents resulting in fatalities, itÂ’s clear that this is a dangerous flight regime. Spin training has become popular in some circles, but there remain substantial questions about how effective it is. There are more than 100 pilots in this database who had extensive spin training Â– many with outstanding backgrounds Â– who still fell into a spin accident.
The ability to perform a spin recovery is often an academic argument, simply because 90 percent of the spins occurred at altitudes that were too low for recovery."
Consider also that you will see an AOA probe on many Cessna Citations or Lears or other of that category of jet. The AOA systems are present on those aircraft for very good reasons.
You may think it is silly, but staying out of the 14 percent of GA accidents that leave a smoking hole in the ground following a low level spin does not strike me as silly.
