There are a couple of different models of the AT-802. The AT-802's equipped for agricultural "crop-dusting" spraying equipment are: the AT-802 (single-seat cockpit). The aerial fire fighting AT-802 is known as the AT-802F. Air Tractor makes a double-seat cockpit version of both models, designated by the letter "A". See this webpage for information on the AT-802 models.

Here are links on specifications and performance for the AT-802F. For those of you who want a more detailed discussion, I refer you to a couple of posts I made one year ago on the AT-802F (updated as appropriate) here and here.
