What is anticipated blind?
When terrain/environmental factors cause a loss of visual cues for a short duration or when visual cues are lost when using a pre-coordinated non-visual station keeping that provides sufficient situational awareness to ensure deconfliction
What is unanticipated blind?
Visual cues required for formation separation no longer provide sufficient distance, aspect, or closure rate cues to ensure deconfliction. Could also occur when non-visual methods do not provide sufficient situational awareness to ensure positive deconfliction.
