Analog instruments may require calibration every 6 months. Refer to the specific Instruction Manual for more information.

The information on the latest manuals and information letters can be found on the GSTE page here 

What is the difference between calibration vs bench check? 

An inspection/verification from a third-party, non-Barfield authorized repair station, is not considered recertification of the Test Equipment. It determines, at best, if the Test Equipment’s performance meets Barfield’s published specifications.  It is important to clarify that Recertification does NOT result in any adjustments to the measurement system. 

The process of Calibration requires the Unit Under Test (UUT) be compared to Certified Traceable Standards.  Adjustments are made to the UUT during calibration in order to align the UUT to the exact values of the Standards so that the errors at all required test points are zeroed out. 

A true Calibration results in the equipment operating at its optimum accuracy and performance levels, which ensures the instrument will maintain its performance specification for another year until the next annual calibration recertification is due.    

In summary, the recertification (calibration) is normally required to be performed every year; “inspection-verification” is NOT recertification. 

Where can I send my Barfield equipment for calibration and repair? 

Barfield Test Equipment can be sent to Barfield Headquarters. Please, contact our customer support at

Interactive Dashboard Tracking Passengers in US Airports

Interactive Dashboard Tracking Passengers in US Airports

One of the different metrics that Barfield uses to measure the health of the aviation industry is tracking the number of passengers throughput from the Transport Security Administration- TSA. TSA has created a table  that records the number of Total Traveler Throughput daily for 2020 and 2019. Given the importance of this information for the aviation industry, our analytics team used TSA information to create a better, user-friendly dashboard, making it helpful for analysis.

Explanation of tables and charts:

The TSA dashboard has the ability to filter by date ( middle section in blue – Select Date Range).  The information displayed at the top is the total number of passengers. At the bottom left is the total number of passengers on a logarithmic scale, which provides a better comparison of how the data is trending between years. This is in consideration of the large gap when comparing before and after COVID. At the bottom right is the total amount per year and ratio of total passengers between the two years.

The data filter section updates all tables simultaneously.

Try interacting with the TSA dashboard below. Click on the bottom right arrow to expand.

As aviation continuous to recover, our analytics team is interested to learn what other key metrics are the different companies in aviation tracking.  

Our team will try to update this chart as often as possible.
