Tracking flight time is important.  Also providing count timers is required for IFR flight....not a count timer per se...but a clock showing seconds.  Having the timer just makes like a bit easier.

Flight Timer

Each flight is tracked and the flight time is saved in the flight summary.  During your flight notice the flight timer in the upper right hand area of the display.  You have the flight time in HH:MM:SS and also the flight time in 1/10ths of an hour....traditionally how you record time in a log book.

Count Timers

You can have 6 saved timers set to anything you desire.  The count timer will count up or down and is displayed all the time.  You can modify these to be any time you want.
