Air Tractor has a web page on the AT-802F . I posted a link to the later page a couple of days ago, so if you have not checked out, check it out now. If for no other reason than to see some spectacular pictures of the 802F and the 802F Fire Boss in action.
I will be writing about the AT-802F (either the single-seat cockpit version or the two-seat cockpit version) as well as the AT-802F “Fire Boss”. These Air Tractor models have what is known as the Air Tractor Fire Retardant Delivery System (FRDS). I refer you to this link for more information on the AT-FRDS II system. I think it is self explanatory.
there are other systems available, including home-made systems in use that are not USFS or BLM approved. These other systems may be used by State aircraft or other 802’s not available for a nationwide tanker contract. Generally, the after-market and home made conversions are done on older aircraft where the installation of a FRDS system is not economically feasible or needed.
For a very good and short video of an 802F in action, including shots of the FRDS, check out this youtube video.
updated information (as of January 28, 2010). At the time that I wrote the above, I only knew about one approved SEAT door system approved by the IAB, the FRDS I system. Sometime in the last few months a newer model of the FRDS SEAT door system -- FRDS II -- was put on the market. At the time I wrote the original article, there was information available on the web through Air Tractor (I believe) on the FRDS I gate system that I linked to in February 2009. That link has since expired. With the advent of the FRDS II system I have not been able to find any obvious information on the net about the FRDS I system that is still being used in many AT-802F's (e.g. Queen Bee's). Moreover, I recently found out that there is another computerized SEAT gate system that has preliminary approval by the IAB, known as the Hatfield Gate. I expect to writing about the Hatfield Gate system in early February 2010, so stay tuned.
