Timer – Chrono Stopwatch

Enter a custom time in MMSS (4 digits) format.

A timer is used in aviation to monitor and track various in-flight timed operations and critical ground events such as engine startups, starter duty cycles, and pre-flight checks. Most modern aircraft are equipped with a dedicated 'chrono' button on the cockpit panel, readily accessible to pilots. This feature functions like a stopwatch, allowing pilots to start and stop the timer at their command to measure specific time intervals accurately. Timers are essential for ensuring safety and efficiency in flight operations, helping pilots adhere to strict procedures and manage time-sensitive tasks effectively.
