The Smart Way to Meet Event Reporting Requirements

The AFDAU-T1 provides automatic bucket calibration and digital data collection. Simplifying the need to meet reporting requirements for aerial firefighters. The AFDAU-T1 is compliant with the U.S. Forest Service’s (USFS) ATU requirements.

Connecting to sensors onboard, the AFDAU-T1 processes data and generates events in real-time using highly accurate algorithms.


Complete visibility over your events

Accurate, reliable, affordable and requiring absolutely no pilot input, it’s the smart choice for aerial firefighting operators.

Automatic Data Collection for Accurate Reporting

AFDAU-T1 accurately and efficiently records information on bucket operations, including bucket capacity, volume dropped, engines tarts/stops, aircraft takeoffs/landings.

Automatically Detects Container Capacity

AFDAU-T1 automatically adjusts to your bucket or tank capacity toensure accuracy and efficiency. No pilot interaction is required evenwhen swapping buckets in a slung load configuration.

Paired with RockAIR or DZMx, meets NAFC Standard OPS-14 Requirements

AFDAU-T1, when paired with a cellular/satellite unit from TracPlus, meets NAFC Standard requirements for tracking, event data collection and messaging.

Data Securely Stored and Displayed with TracPlus

Paired with RockAIR or DZMx, AFDAU-T1 seamlessly and securely sends operational data through cellular / satellite to your TracPlus account for easy analysis and reporting.

Easy installation and minimal pilot input

The AFDAU-T1 ATU is easily installed into your aircraft, and once installed, requires minimal pilot input in a busy cockpit.

Reliable, Accurate and Cost-Effective

The AFDAU-T1 ATU is a cost-effective solution to capturing reliable and accurate operational data.


Events reported automatically to NAFC's ARENA software include:

  • Real time GPS position of events
  • Engine start and stop,
  • Take-off and landing,
  • Entry and exit from hover,
  • Fill and drop events - including fill/drop volume, drop type (split or full) and product type (water, gel, foam, retardant)

“NAFC has followed the development of the AFDAU-T1 unit closely and are encouraged to see this equipment become available for Firefighting Aircraft in Australia. NAFC is pleased that there is now an additional device on the market for operators wishing to fulfil contractual event reporting requirements, particularly the difficult task of reporting firefighting bucket fill and drop volumes.”

“These old systems were hugely costly to purchase, and even more costly to an operator when they fail in the middle of a busy firefighting season. We created AFDAU-T1 to be affordable, easy-to-use, and to reliably capture accurate data to minimize risk of non-payment. With AFDAU-T1, everything is automated.”

“In 2018, we started to trial AFDAU-T1 in one of our BK117's. We had been looking for an alternate and cost-effective solution to meet our contractual firefighting needs and saw the TracPlus/AFDAU-T1/RockAIR combination as a possible solution. We’ve now collected data using AFDAU-T1 through one very busy fire season and the results have been outstanding. We are now planning to upgrade our legacy systems through the fleet.”
