GNS
400-500 Display & GDL 69 VS True Flight
Comparison |
|
Customer
testimonials. |
|
|
|
|
This comparison will hold true for either
the Flight Cheetah, LS 800 EFB tablet or
TrueMap software on your own computer . |
|
|
|
|
|
|
|
Why buy a
Flight Cheetah LS 800 or TrueMap instead of adding the
GDL 69 option to your existing
Garmin 400-500 display ? The Garmin
400-500 displays have been
immensely popular over the
years. The question though when you
move towards a data link purchase is
which system will offer you the most
logical, and comprehensive solution
to increased safety in the cockpit for the type of flying you do.
|
|
|
|
|
|
|
If you purchase a GDL 69 add on to
your GNS 400-500 display instead of
a Flight Cheetah with the XM Weather these are a few of
the following capabilities you miss
out on. |
|
Larger
easier to-read-screen, uninterrupted
operation during total in-flight
electrical failure, WAAS GPS,
contour terrain, airways, enroute chart
overlay, approach overlay with
altitudes,
obstacle mapping, cheapest fuel
price search, artificial horizon
option, 2 way in-flight email
option,
lightning, echo tops, IR satellite cloud
cover,
temporary flight restrictions, TAFs,
winds aloft, fastest
flight level search, and enough savings to
cover the cost of your XM
premium aviator service for 3 years

Although
previously stated in advertising that Garmin
400-500 series displays would provide
additional weather products when the required WAAS
upgrade is available, Garmin has now stated
that
there
are no plans to add additional weather
products to them.
