ccasionally, the lines cross between a
community issue and the availability of
a tool to mitigate that issue. Early 2014
gave us a prime example with arguably the first outgrowth
of prior-year efforts to update Part 23 rules.
The result: Several new options for more-affordable
angle-of-attack (AoA) systems that are made possible
through the Federal Aviation Administration's acceptance
of ASTM standard, F3011-13.
Reducing loss-of-control accidents is a current top
target of safety experts; AoA systems are viewed as
an underutilized tool in general aviation, one with great
potential to reduce loss-of-control accidents.
Thanks to the consensus-standards approach, AoA
systems available under ASTM standard F3011-13 are
already shipping. And they come to market in time to
meet an increase in demand expected from a public,
relatively recent focus on loss-of-control accidents and
how to reduce their frequency.
