An aircraft clock is built to be resistant to extreme temperatures, vibrations, and electromagnetic interference and it is much more than a mere timekeeping device. They are also incharge of: 

  • Precise flight planning

  • Navigation tasks 

  • Instrument approach procedures

  • And synchronization with air traffic control systems. 

Without reliable clocks, the efficiency of aviation operations would be compromised. But now that we understand what aircraft clocks are and how they are made, let’s take a look at the different types of aircraft clocks. 

The 4 Main Types of Aircraft Clocks

Aircraft clocks are categorized based on their functionality, design, and features. Let's explore the various types and their specific roles:

Type 

The Role They Play

Primary Flight Clocks

They are integrated into the aircraft's primary flight display system and provide vital information, such as time, elapsed flight time, and flight data recording, ensuring accurate timekeeping during critical flight phases. 

Secondary Flight Clocks

They are designed to automatically activate in the event of a failure in the primary clock system and serve as backups to prevent mission-critical tasks from being compromised, maintaining the safety of flight operations.

Chronometers

They are highly accurate timekeeping instruments and are crucial for calculating distance, fuel consumption, and navigation waypoints to ensure accurate navigation and precise timing during flights.

Clock Systems

They are highly advanced devices, and include multiple clocks interconnected to provide synchronized time information to various onboard systems to ensure consistent timing for all critical operations. 


By understanding the types of aircraft clocks, it becomes evident that these timekeeping devices are indispensable for safe and efficient aviation operations. Now let’s go on a blast to the past to further understand how these devices have evolved through the years.
