A first light search can be waived when there is a high probability of survival. This condition implies that evidence or circumstances suggest that the individuals in distress have a good chance of being located or rescued without the immediate need for a search. Factors such as favorable weather conditions, the individual's known location, or other situational awareness data may lead search coordinators to conclude that delaying the search until first light won't significantly impact survival chances.

In contrast, waiving a first light search due to low probability of survival or dangers in the area does not effectively utilize time when the possibility exists that individuals may still safely be reached or recovered. Additionally, coverage of the area by a search response unit would generally indicate that a search is ongoing or has been attempted, rather than provide grounds for waiving the search. Thus, in cases where there is a high probability of survival, the decision to waive the first light search reflects an assessment that keeping personnel and resources ready for later action could be more effective while prioritizing safety.
