AeroNav Nav Com and the current state of modern GPS Navigation Systems

Today’s modern, glass-based digital avionics offer many advantages that make flying much easier, safer,
and more enjoyable than legacy, analog instruments. 

Whether you use VFR or IFR, fly short or long distances, overland and/or water, these modern instruments 

can reduce your workload, offer higher reliability, (therefore, increased safety), and provide connectivity,

all with easy-to-use interfaces.

Specifically, a 3-D global navigation satellite system (GNSS) has brought a major leap in precision, safety,

and coverage relative to the traditional VOR-based navigation. GNSS offers precise, repeatable, and
predictable 3-D flight paths that alleviate the constraints of physically-located, ground-based navigation
methods. Its use enables new route structures which result in greater efficiency – more routes fit into
the same airspace, resulting in increased capacity. In addition, GNSS offers major enhancements in
awareness information, e.g., terrain, weather, and traffic. Joseph T. Nall Report in 2019 offers detailed
insights into the reduction of fatal accidents in General Aviation. The major reason: “…weather accidents—a topic of major
emphasis in the industry’s safety awareness campaign—fell off sharply year-over-year from 39 total
accidents to a 10-year low of 23, and from 30 fatal weather accidents to 12. As usual, most were
attributable to VFR flight into instrument meteorological conditions 1 .”


Furthermore, GNSS can offer continuous descent approach from cruising altitude to save fuel and
reduce emissions and noise.


Economically, prices for these new navigational systems have steadily reached affordable levels that make

a transition to them much easier on your wallet. Nevertheless, when selecting an instrument, the economics

is only one dimension in your decision process – system availability and precision, for increased safety, relative

ease-of-use, time-to-installation, and connectivity options must also be considered.

As a leading vendor, BendixKing is committed to advancing avionics that addresses the deficiencies and
limitations of legacy products. Specifically, Bendix King’s AeroNav navigational product suite offers a wide
range of features that make flying easier and more enjoyable. The product suite is designed for Part 23
and Part 25 aircraft owners and OEMs. It is a feature-rich, hybrid touchscreen/physical-knobs
GPS/FMS/NAV/COM, and was designed to be easy-to-use, with intuitive interfaces. For example, it can
reduce data entry, e.g., waypoint entries, by as much as 75% relative to legacy systems. This makes it
much faster and easier to enter and edit flight plans. It also dramatically reduces “head-down” time. The
product line is compatible with a large number of popular ADS-B Out transponders. It is also an
approved position source for ADS-B. This means there is no need for a separate GPS (or ADS-B with
embedded GPS), therefore, less equipment is required, lowering the cost of purchase and installation. It
also means there is no need for an additional antenna on the aircraft, which would further decrease
overall cost.

Furthermore, 3-D synthetic vision is fully integrated in all AeroNav models, at no additional charge. They
all include in-trail synthetic vision display which provides a significant enhancement to situational
awareness. This advanced feature gives the pilot a view that she/he needs right on their navigation
screen, providing a 3-D presentation of the flight plan, color-contoured terrain, nearby obstacles, and ADS-B
decline traffic when paired with an approved ADS-B source. The AeroNav adds an out-the-window synthetic

vision view, as well for PFD-like performance - including a lateral and vertical deviation of LPV approaches.

The product line also offers major advanced safety features listed below.


1. 3D Terrain, Obstacles and Traffic – provides visual and aural alerts about the terrain. Standard traffic
symbols with traffic depictions indicate relative threat level by their size, and relative altitude
and bearing. As traffic draws nearer, the size of traffic symbols increases on AeroNav’s screen.


2. Predictive Terrain Collision Alert – offers an extra measure of safety by providing visual and
aural alerts if controlled flight into terrain is projected. This feature also includes a TAWS-like
500’ foot callout if the aircraft descends below 500’ MSL based on GPS terrain.


3. Low-Fuel Alerting – When coupled with a compatible fuel totalizer, AeroNav will display a
dashed green circle, indicating a fuel reserve of 45 minutes.
Many other advanced features are designed-in the AeroNav product line, e.g., Wi-Fi and Bluetooth connectivity

that enables a pilot’s favorite flight apps will always be part of her/his toolkit. 


4. Autopilot Capabilities – The AeroNav series offers the ability to drive advanced autopilots such as the AeroCruze 230

and others. Check here to see if your Cessna, Beechcraft, Piper, or other major airframe is listed below.
