(Answered) Arrow IV ADA munitions

[corruptone]

1) How, exactly, is this handled on the to hit?  Is it direct fire like shooting a PPC but with the Flak modifier and Range based on mapsheets or different?

2) How is the damage handled?  Is it similar to the homing as in 20 pts to one location or is it put in 5 point groups


Thank you very much for your answers.

1) Direct-Fire, like all flak attacks, with flak modifier.

2) A single 20 point hit.
