In 3.5, a character can end their turn mid-jump if they run out of movement for that round but they have not finished their jump. Is such a character considered to be flat-footed, as is a balancing or climbing character? How might that affect feats such as Deflect Arrows?
The Player's Handbook simply says:
If you run out of movement mid-jump your next action (ether on this turn or, if necessary, on your next turn) must be a move action to complete the jump.
It says nothing about becoming flat-footed or denying you your Dexterity bonus to AC so you aren't flat-footed. As attempting to deflect an arrow isn't an action according to the Feat, you can still use it mid-jump just as you could if you were on the ground.
