When Kanan Jarrus Crew is equipped to an attached shuttle , the Ghost can clear stress with white maneuver, correct ?

When the Shuttle is still docked with the Ghost , the pilot ability of the Shuttle and all of the upgrades equipped to the shuttle are not in play yet, and therefore cannot be used. The one and only exception is the Phantom title.

The Shuttle pilot's ability and upgrades only become active when the Shuttle is deployed.
