The Astrotech LC-2 is a precision clock-timer offering reliability at an economical cost.
This chrono-meter provides time, date and elapsed timer with a hold or time-out feature.
The Astrotech model LC-2 chronometer uses a custom designed microprocessor circuit which
controls all clock/timer functions. The microprocessor is attached to a single circuit board, a
simplified construction technique resulting in a high degree of reliability and performance at a
low cost. Circuitry is not subject to dirt, vibration, friction, or the wear characteristics of mechanical
clock movements.

24 hour elapsed timer
Date display
Internal lighting
Two year battery life
Rear mounts into standard 2-1/4" diameter instrument panel cutout
Clock: 12 or 24 hour, 4 digit clock, internally switchable before installation.
Elapsed Timer: 24 hour capacity, displays minutes/seconds for the first hour, hours/minutes thereafter to 100 hours.
Date: Displayed in MONTH/DAY format.
Timing Accuracy: Typically better than a few seconds per month.
Display: Continuous readout using a Liquid Crystal Display for excellent readability in direct sunlight.
Lighting: The display is lighted for night flying and connects to the aircraft instrument panel dimming circuit. Both 14V and 28V bulbs are included with each panel mounted clock.
Power: If equipped with batteries, the life is normally 2 years. The power drain when connected to the aircraft battery is negligible (less than .003 Amps).
Weight: Less than 5 oz. (142 grams)
Installation: Installs directly into a standard 2-1/4" (57.2 mm) diameter clock panel cutout for the panel mounted LC-2 or mounts in the specified aircraft control wheels.
Environmental: The LC-2 is qualified to all of the applicable sections of RTCA DO-160 for electrical and mechanical compliance.
