About three and a half years ago I bought a B36TC with the
intention of using the airplane to fly into high altitude airports
in the Rockies. Some of the features that I liked about the
"B" model beginning in 1984 were the longer wing,
different panel configuration, and of course the turbocharged
engine. After completion of the Whirlwind II TCP conversion, I
began looking at glass cockpit options. It didn't take long to
settle in on one product that I thought was head and shoulders
above all the competition, and would stay there for quite some
time: Chelton Flight Systems EFIS
So what's the difference in the glass cockpit products? The
Garmin G1000 and Avidyne are 2 dimensional. Both have done a great
job in packaging their products. They look beautiful. Put aside
the fact that neither unit is STC'd for the aftermarket yet, and
not expected to certify for many years. The Chelton PFD is a full
3-D presentation that increases your situational awareness. As I
see it, Garmin and Avidyne have re-packaged the attitude
indicator, as well as the rest of the flight instruments including
the nav-coms and transponder into a beautiful product. Chelton,
has taken the EFIS display in a different direction.
Chelton Flight Systems offers a complete package that consists
of two flight displays: the PFD, and the MFD (additional MFD's are
an option if desired). The FlightLogic EFIS combines advanced
Heads up Display (HUD) symbology with real-time forward-looking
3-D terrain that is WAAS certified to create a Primary Flight
Display. The result is tremendously enhanced awareness, and
dramatically reduced pilot workload. Imagine for a moment, you're
in the clouds, on a step-down descent into a mountain destination
and the EFIS displays the ridges in front of you in 3-D. In
addition, the HITS presented in the EFIS give descent guidance as
though you were on an ILS approach. The MFD depicts the course
line as well as the terrain, as though you were looking down from
above, giving the pilot the ability to "see around the next
bend", and behind the peak in front of the airplane as viewed
on the PFD. The 3-D Synthetic Vision EFIS enables you to always
"see" the terrain (including the airport environment)
ahead of and around your aircraft for remarkable situational
awareness, command awareness, control and safety. In fact, NASA
documented that over the course of 945 flights there was an 85%
reduction in Flight Training Errors (FTE). This, according to
NASA, translates into a sevenfold improvement in safety.
The Highway-In-The-Sky feature creates a virtual 3-D skyway
"tunnel" for all enroute and instrument procedures. You
simply fly your aircraft through the boxes which makes executing
flight plans and procedures almost effortless. Chelton has also
added the capability to designate precision VFR approaches to any
landing area. It is a different presentation of the CDI and HSI.
These "boxes" give course guidance and vertical
navigation that is overlayed on the EFIS. There is an artificial
horizon line on the EFIS that indicates the aircraft's altitude
extended ahead.
The MFD can show a variety of functions including a moving map,
traffic, weather (singly or in combination), a conventional HSI,
and a reversionary flight display. The vector moving map displays
color-coded terrain, Jeppesen NavData, and water, (traffic is also
shown on the PFD). A horizontal projected path extending from the
nose of the aircraft symbol shows the turning ground track of the
aircraft one minute into the future. The map can be viewed in
radar-sweep or position-centered (full compass-rose) format in
either heading-up or North-up orientation. Map scale ranges from
0.5 to 400 miles. The dead-stick glide area- corrected for turns,
wind, terrain, airspeed, altitude, and descent rate is shown as a
blue line around the aircraft.
The transition from steam gauges to the EFIS did not take as
long as I thought it would. After a few hours of flying with the
Chelton I became quite comfortable with both the airspeed and
altitude tape. My old instrument panel consisted of a Garmin 530
and 430, which I used to its design capabilities, always
programming a flight plan into the computer instead of selecting
"direct to". So using the flight planning function of
the Chelton was SOP (standard operation procedure) to me. While
the two products are not the same, they are similar in concept in
regard to the flight planning option. There are some procedures
regarding data input that do take some time to become proficient
at, and should not be treated lightly.
As I mentioned earlier in this article, incorporated in the
EFIS is the "forward looking synthetic vision" feature.
The visual depiction includes full ground mapping which includes
buildings, towers, mountains, and the runways. So imagine this
scenario. The ATIS is reporting: "sky overcast, ceiling 200
ft, visibility one quarter mile in fog", you are in the
center of the HITS, you are right on the glideslope, and centered
on the localizer. And from inside the FAF, you "see" the
runway on the EFIS right in front of the airplane. Remember the
"HITS" boxes continue to give course and descent
guidance on non-precision approaches as well.
The installation is not to be taken lightly. Consider this. The
entire panel should be reconfigured. The pilot has the opportunity
to create his own panel, placing instruments where he or she would
like them (as I did). My installation and new panel were done at
O&N Aircraft in Factoryville Pa. Bill Miller was extremely
competent. When my installation was completed everything worked as
advertised. And was delivered on budget, as quoted.
Just a note here. If you're flying a Super King Air, Lear Jet,
Citation 10, Challenger, or a B36TC, the equipment would be the
same. Even the GlobalFlyer used the Chelton EFIS as the primary
source for flight instrumentation.
