I wonder, could Passive Sensors cause Coordinate to fail, if the only ship within range had a spent-charge Passive Sensors?

I'm leaning towards yes, the Coordinate actively fails.

While a ship coordinates, the coordinate fails if no friendly ship can be chosen.

If the chosen ship attempts to perform an action but that action fails, the coordinate does not fail. (Coordinate, p.8)

Passive Sensors prevents a ship which has spent it's charge from being coordinated. As I read that, it seems to suggest that the PS ship cannot be chosen. It's not that the PS Ship can be chosen but cannot perform an action, as would be the case when a stressed ship is coordinated--a known example of a case where Coordinate does not fail, but generally has no practical effect. AP-5, Primed Thrusters, and Chopper-crew all enable a stressed ship, when coordinated, to perform some actions. But Passive Sensors uses a different kind of language, with that "cannot be coordinated." Again, I'd read it as preventing the ship from being a valid choice *at all,* which to me implies failure.

For context, the list I'm pondering:

• Lothal Rebel (Passive Sensors, Saw Gerrera)
• Hera Syndulla (Composure, Advanced Sensors)
• AP-5
• 4 points of wiggle, maybe Zeb crew on Hera, maybe Chopper pilot over Lothal Rebel, maybe just 2x Hull Upgrade

The timing for Comms Shuttle on the Sheathipede is clearly before the timing window on Advanced Sensors, so Hera would be able to Coordinate (into Composure Focus) + Action before she does a red move. Presuming that Passive Sensors' charge being spent means Coordinate fails, you'd just have two easy double-modded 4-dice attacks.

seems like this works no problem. when you perform a coordinate action, it fails if no friendly ship can be chosen. a ship with passive sensors equipped and the charge inactive cannot be coordinated.

when you fail an action, composure triggers and lets you perform a focus action. comms shuttle happens before a ship activates, so hera can still use advanced sensors to perform an action before executing her maneuver after performing the coordinate action granted by the sheathipede that's docked.
