WICHITA, Kansas — Mid-Continent Instruments and Avionics has introduced a line of multifunction digital clocks.
The new CHRONOS Series features eight modes of operation: Local Time, UTC/Zulu Time, Flight Timer, Countdown Timer, Stopwatch, Volts, Outside Air Temperature (OAT), and Secondary Air Temperature.
The clocks are available with single and dual USB chargers and deliver up to 75 watts of USB power.

“There was a clear gap in the market for modern, multifunction clocks,” said Matthew Harrah, senior vice president of technology and products for Mid-Continent Instruments and Avionics. “First and foremost, panel space is a premium. Our customers wanted more built-in functionality and access to fast-charging USB power, all-in-one.”
He added the new clocks are an “easy upgrade during routine maintenance,” and fit a standard, 2-inch panel cutout.

The new six-digit, seven-segment clocks feature external lighting control and a built-in photocell for automatic dimming. An internal, field-replaceable battery maintains time and flight timer memory, without aircraft power.
CHRONOS Series clocks are TSO certified and available starting at $499.
I had two analog aircraft clocks with push button stop watch function overhauled at Waltham in Alabama about 5 years ago. They were the only shop I could find to do so. $450 a pop back then.
I am an old guy. When I learned to fly, my goal was to fly the airplane. Now there is more learning in how many functions that button can do. Do I push it, tap it, hold it for how many seconds, and by the way I am VFR. “LOOK OUT”
When the big hand points to the left, set the fuel selector to “left tank”. When the big hand points to the right, set the fuel selector to the right tank. When there’s no big hand…have the clock fixed.
That’s a great idea on a reminder to switch tanks !
However, my Cessna is gravity feed from both tanks, on the ‘both’ setting.
My clock has a seconds hand, so I can time turns , if needed.
I’ll keep the 60 year old , windup clock in my Cessna. It never needs batteries and runs for 8 days.
At engine start, I set it to ’12 noon’. Then if there is an electrical failure, I know how long I’ve been flying and know my fuel use., since the gauges will now show ’empty’.
Great idea! When the EMP bombe goes off, nothing electrical will be working sny more. So yhere’s that, too.
wow – $500 for a clock – that’s crazy. Guess that’s what TSO cert runs these days 🙂
