CX-3
Flight Computer
May be used during FAA and Canadian
Knowledge Exams.
The CX-3 complies with FAA
Order 8080 .6 and Advisory Circular (AC) 60-11, “Test
Aids and Materials That May be Used by Airman
Knowledge Testing Applicants”; therefore, you may
bring the CX-3 with you to the testing centers for all
pilot, mechanic, and dispatcher FAA exams .
Numerous aviation functions.
You can calculate
everything from true airspeed, Mach number, fuel
burn, and holding patterns to headwind/crosswind
components, center of gravity (CG), and many more .
The menu structure provides easy entry, review, and
editing within each function . Multiple problems can
be solved within one function .
User-friendly.
The color LCD screen displays a
menu of functions and the inputs and outputs of a
selected function with easy-to-read menus and data
displays . The inputs and outputs of each function
are separated on the display screen to distinguish
between entered numbers and calculated values,
along with their corresponding units of measurement .
The menu organization reflects the normal process
for planning and executing a flight . The result is a
natural flow from one function to the next with a
minimum of keystrokes: to plan a flight, simply work
from the menus in sequential order as you fill in your
flight plan form .
Non-volatile memory.
All settings, including
aircraft profile, weight and balance data, trip plan
data, values entered by the user, and calculations
performed by the device, will be retained until the
batteries are removed or the user performs a memory
reset . Follow the procedure outlined in Appendix C
on page 20 to back up and restore memory .
Ergonomic design.
The CX-3 features a simple
keyboard and slim design . The non-slip cover
protects your computer inside a flight bag and fits on
the back of the unit for easy storage while in use .
Unit conversions.
The CX-3 has 12 unit
conversions: Distance, Speed, Duration,
Temperature, Pressure, Volume, Rate, Weight, Rate
of Climb/Descent, Angle of Climb/Descent, Torque,
and Angle . These 12 conversion categories contain
38 different conversion units for more than 100
functions .
Timers and clocks.
The CX-3 has two timers: a
stopwatch that counts up and a countdown timer .
The stopwatch can be used to keep track of elapsed
time or to determine the time required to fly a known
distance . The countdown timer can be used as a
reminder to switch fuel tanks, or to determine the
missed approach point on a non-precision instrument
approach . An internal clock continues running even
when the flight computer is turned off . UTC and local
time can be displayed, and the time can be set with
UTC, destination, or local time .
Interactive functions.
The CX-3 is designed so
the functions can be used together . You can perform
“chain” calculations where the answer to a preceding
problem is automatically entered in subsequent
problems . Standard mathematical calculations and
conversions can be performed within each aviation
function .
