GENERAL-AVIATION AIRCRAFT.

Administration to install and use them. So, few to none exist in
light aircraft except among the turbine-powered light jets and
turboprops available under Part 23.
Unless it came with a technical standard order-approved
(TSO'd) factory installation, estimates put the cost of approval
in the hundreds of thousands of dollars - to land the ability
of one model for installation in one model of aircraft under a
supplemental type certificate. That expense would serve to drive
up the retail cost of purchasing and installing a suitable AOA
system above the value of most aircraft that could most benefit
from one's installation.
Then came the urging of a group working to rewrite Part
23, precisely to address the high degree of complexity and
exorbitant costs of the approvals for everything from adding
a safety system to an existing design - like an AOA - to
certificating a new aircraft, a new engine, or new avionics.
Shortly before the 2015 Sun 'n Fun Fly-In, the FAA granted
approval for installing new AOA systems shown to meet
performance standards under an STC process.
From a single STC for one AOA system, availability
expanded through a series of blanket STCs under an approvedmodel-list (AML-STC) process. Suddenly, FAA rules provided
a path to allow owners of small aircraft to install AOA
indicators and other safety-specific systems without making
manufacturers fly through all the old bureaucratic hoops - a
process long required anytime someone wants to try to add new
equipment to the cockpit.
At the same time, the FAA made the process easier for the
manufacturers, allowing them to bring their new AOA systems
to a large, eager market at costs below what it would cost under
the old system. And in a scant few months, several new AOA
systems came to market with low acquisition and installation
costs - and at what can only be described at lightning speed for
the general-aviation market.

Almost as quickly, the Experimental Aircraft Association and
Dynon, a maker of avionics for experimental and light-sport
aircraft, collaborated to follow the same new regulatory path to
STC one, then a second attitude indicator/primary flight display.
This one was announced at the 2016 Sun 'n Fun Fly-In in
Lakeland, Florida.
Thus was born an entirely new wave of avionics, avionics
long available to amateur aircraft builders and light-sport
aircraft makers - and passionately coveted by owners of many
