A no-slip-strip prevents it 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 aircraft profile memory to save weight and balance information for your specific aircraft.
