Phase 1 search

A phase 1 search is a painstaking, thorough attempt, in and around a starship, to locate a person who is presumably injured and unable to respond.

However, since the basic assumption of the search is that the subject wants to be found, a capable person knowledgeable in the layout of the search area and determined to evade their would-be locators could do so.

In 2267, a phase 1 search was initiated on the USS Enterprise in an attempt to locate Lieutenant Commander Benjamin Finney, who was presumed to have been in ion pod, which had been ejected to save the ship. In reality, Finney had faked his disappearance in an attempt to frame Captain Kirk for criminal neglect. (TOS: "Court Martial")

In 2369, Captain Jean-Luc Picard ordered a phase 1 search when Data detected a warp engine breach from the Shuttlecraft Justman during Dr. Beverly Crusher's attempt to prove Dr. Reyga's metaphasic shield worked. However, the Justman emerged from the corona of Vaytan before the search could be implemented. (TNG: "Suspicions")
