Both ADP's will run on the take-off roll and will turn off something like 10 secs after airborne. (Engine failure (bleed loss) and TAC operation).
Both ADP's will run for u/c retraction.
Both ADP's will run for stall protection (autoslats)
One ADP will run in the landing mode from approx. 30ft AGL until a few secs (5?). after the speed brake lever is stowed.
One ADP will run during landing gear extension and flap operation.
Pump operation logic is BOTH in AUTO single pump operation the (HYDIM cards select which pump to equalise wear).

i think!
