onfusion continues over what kind of equipment the
federal aviation regulations require to use in homebuilt
planes for instrument flight rules flight. General
aviation today offers multiple options in different categories of aircraft
each requiring specific training and qualifications to operate.
For example, ultralight aircraft, as proscribed by Part 103.
Absent an airspace requirement, most ultralights, powered
and nonpowered, require none of the usual operational qualifications:
No medical certificate; no operator's license; and no type
certificate. The ultralight needs to meet only the definition of an
" ultralight " in Part 103:
If powered:
1. Weighs less than 254 pounds empty weight, excluding

3. Is not capable of more than 55 knots calibrated airspeed

4. Has a power-off stall speed which does not exceed 24

5. If nonpowered, a maximum weight of 155 pounds.
As long-time ultralight flyers will note, while not required by
federal aviation regulations, training is the smart approach,
whether coming to ultralights as a zero-time trainee or whether

the U.S. avionics industry,

existed, albeit not widely due to the
limited market - a market limited
because of the cost and complexity
of winning approval from the
Federal Aviation 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
approved-model-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 lightsport
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

mong the most prominent of my earliest memories
of traveling by private aircraft are the steps to take
before boarding the aircraft, closing the cabin door
and lighting the powerplant fires. Oh, for the convenience of
in-flight connectivity systems and the age of uninterrupted
connectivity of today.
Back then, knowing that ahead awaited several hours in
the relative isolation of the cockpit or cabin, it seemed prudent
- and important - to close the loop on any unanswered calls,
respond to emails in my in-box, and inform a select group
of contacts of my impending period cut off from the world as
the aircraft sped through the airspace en route to that trip's
destination.
Providing an estimated time of arrival seemed both prudent
and polite, but only as long as those folks understood that an
element of uncertainty accompanied the vagaries of privateaircraft
travel. Flight conditions routinely challenged our flight
planning, rendering that calculated ETA into a guesstimate of
uncertain reliability.
A bodacious headwind assured us that our estimate would
be optimistic; we would be later than our ETA. An equally
strong tailwind guaranteed the opposite outcome - from a
degree of pessimism to a holy cow, we're early!
And those folks waiting in the lurch might get a hint by
asking the flight desk to check on our progress via a flight
service station contact to update what we thought we knew
about weather conditions.
For some business-turbine aircraft and some airliners,
a flight phone provided a possible link through which
someone on the aircraft could drop a dime - a couple dozen,
actually - to call ahead with an update on ETA provided by
the flight crew. Otherwise, aside from VHF and/or HF radio
transceivers, contact with folks expecting our arrival awaited
our landing, for us to taxi onto the ramp and disembark on a
beeline to the nearest phone.
Veteran road warriors knew to pack their briefcases with
materials to peruse en route. That option became more useful
and productive with the introduction of laptop computers
and continues to evolve in today's age of tablets and
smartphones.
This brings us to today's world of unending connectivity
and the near-impossible task of finding the quiet of
disconnection.
Size matters for IFC systems
The proliferation of in-flight connectivity systems for
business-turbine aircraft from midsize jets up occurred
because, well, in the case of the aircraft itself, size matters.
Not only are such systems expensive and demanding
to install, the size of the components and, in particular, the
antennae largely eliminated smaller aircraft from eligibility.
Modems and routers required space and power that many
smaller aircraft lacked.
Smaller aircraft face many challenges when it comes to
in-flight connectivity, from fitting the hardware and antenna to
providing the needed electrical power. Merely installing the
connecting wiring harnesses into the structure made such
installations a challenge.
Even when that size issue and the cost of the equipment
could be resolved, there is the cost of service. Equipment
installation is complex, and the cost of data can be expensive.
Additionally, smaller aircraft suffer from limited options for
Wi-Fi installations because of antenna restrictions - issues
avoided in larger business jets and turboprop aircraft. But,
