Under what conditions must practice lost wingman be flown?

Practice lost wingman maneuvers should be flown under visual meteorological conditions (VMC). This is crucial because VMC typically indicates weather conditions that allow for sufficient visibility, enabling pilots to maintain visual contact with other aircraft and the external environment while performing these maneuvers. In VMC, pilots can effectively manage their separation and avoid potential hazards.

Flying practice lost wingman in VMC is essential for safety, as it allows pilots to visually confirm their position relative to the wingman and the lead aircraft, making it easier to execute the maneuver appropriately without relying solely on instruments. Conducting this practice in conditions that are not visually clear could compromise safety and situational awareness, which is why VMC is the preferred condition for such maneuvers.
