In case the 11 air tanker studies since 1995 are not enough, there is now a twelfth. As you can see on the cover above, it is named Analysis of Aircraft for the Fire Fighting Mission in Colorado. It compares four different aircraft, two of which have received certification from the Interagency AirTanker Board, and two that have never been converted into air tankers:
The study is Colorado-specific in that it looks at the retardant capacities if the aircraft were to fly out of four air tanker bases in the state: Denver, Durango, Grand Junction, and Pueblo, with elevations ranging from 4,726 to 6,685 feet, and runway lengths from 9,000 to 10,502 feet.
The study primarily considered four characteristics of the aircraft:
- Retardant tank volume (certificated or estimated)
- Mission payload capability from USFS air tanker bases in Colorado
- Sustainability and after sales product support
- Mission effectiveness expressed as gallons transported per hour and per day
The C-130J/Q led the field in all four categories.
Assuming the data compiled by Conklin & de Decker Aviation Information is correct, the retardant capacities at the Colorado air tanker bases “during typical summer temperatures (ISA + 30 degrees C)” for the C-27J and S-3B are stunningly low, averaging 184 and 181 gallons, respectively. The BAe-146 would have to download from the maximum of 3,000 gallons to 1,884, while the C-130Q/H would always, according to the report, carry their maximum load of 3,500 gallons.
The tables below are from the study on page 33.
We are curious to know who paid for the study, which was “prepared for [Colorado state] Senator Steve King”. A phone call to Conklin & de Decker Aviation Information was not immediately returned. Senator King has been very interested and vocal about the possible acquisition of firefighting aircraft for his state.
Earlier this year legislation passed in Colorado that allowed for the creation of a “Colorado Firefighting Air Corps”, but it did not authorize any funding for the agency. The bill was introduced by Senators Steve King and Cheri Jahn
