Narrative:

I was working the tmc position. The arrival coordinator position was also combined to me and I was handling those duties during this period. I spoke with a coordinator for aircraft X via telephone. During this time we discussed his request for a parachute simulation just east of phx. My understanding was this was going to be a simulation run with three passes dropping streamers. I advised due to departure traffic there may be a delay for his requested time but felt confident I could work out this request within our facility and phx tower. Aircraft X was airborne around the coordinated time. We held the aircraft X aircraft for approximately 30 minutes due to departure traffic off of phx. I coordinated with the phx tmc to stop departures to allow for aircraft X to make his run. Aircraft X advised our controller he would only need one run which worked out better for both P50 and phx. After departures were stopped aircraft X started his run. Once over the target aircraft X advised his run was complete and would rtb [return to base]. Once aircraft X was no longer in the departure corridor I released departures at phx. Shortly after this; aircraft Y started his roll and climb out. Tower called and advised aircraft Y was making an immediate right turn to avoid parachute jumpers just east of phoenix. I acknowledged this and advised the south departure controller. I also advised the flm at this time. These jumps should be coordinated well in advance. Going forward I will need to verify that there are or are not jumpers during coordination.

Original NASA ASRS Text

Title: P50 TMC describes a situation where an aircraft is supposed to make three runs over a target; then when airborne changes its plan and drops skydivers unknown to ATC. Departing traffic has to deviate around falling skydivers.
