CX-3® Flight Computer
The most versatile and easy-to-use aviation flight computer for fast, accurate flight planning and calculations. Using the latest microchip and display technologies, the features and functions of the CX-3® make it the most useful aviation calculator available. Includes 4 AAA alkaline batteries.
The CX-3® Flight Computer makes flight planning simple by taking confusion out of the equation. Fast, versatile and easy to use, the CX-3® delivers accurate results quickly and efficiently. It can be used on all FAA and Canadian pilot, mechanic, and dispatcher knowledge exams. Whether used for flight planning, ground school, or knowlledge testing, the menu organization reflects the order in which a flight is normally planned and executed, resulting in a natural flow from one function to the next with a minimum of keystrokes
Multiple aviation functions can be performed on the CX-3® flight computer including those related to time, speed, distance, heading, wind, fuel, altitude, cloud base, standard atmosphere, glide, climb & descent, weight & balance, as well as a holding pattern function to help determine entry method and holding details. A calculator, clock, timer and stopwatch are also built in along with mutliple settings for lighting, backlighting, themes, time zones and more.
The sleek design, and ergonomic fit and finish of the CX-3® make for easy transport. The protective cover comes off the front and snaps onto the back of the computer. A no-slip-strip prevents the CX-3® from sliding around on smooth desk surfaces. A Theme feature provides a convenient way to switch from Standard view to Night or Daylight views. The backlighting feature controls the brightness or intensity of the screen, and the buttons on the keypad will light up in Dusk and Night modes for use in darker environments. A Favorite feature provides quick access to your most frequently used function and store the Aircraft Profile will let you store numbers specific to your aircraft.
Numerous Aviation Functions
Calculate everything from true airspeed and Mach number, fuel burn, holding patterns, to headwind/crosswind components, center of gravity (CG), and everything in between. 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, for easy-to-read menus and data displays. The inputs and outputs of each function are separated on the display screen so it is clear which numbers were entered and which were calculated, along with their corresponding units of measurement. The menu organization reflects how a flight is normally planned and executed. 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.

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 factors for over 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, destination and local time can be displayed, and the time can be set with UTC, destination or local time.

The Answer
Format: Imitation Leather
I purchased this book of Devotions as I was looking for a guide that would be simple to follow and compact. It seemed like I always was making excuses for not being as diligent with my faith. It was easy to tell my self that I could not keep up with God or travel with a guide as it was too inconvenient or bulky. From a content and simplicity to stay focussed, this was the source I needed. From a convenience standpoint, it could not be any better. I had tried apps and digital versions previously and it just wasn't the same. Holding a book and leafing through the pages just feels so much better to me. A definite must for those of you looking for a impactful, yet small and convenient way to continue the journey.
