True or False: You must not descend below 100' above threshold elevation using approach lighting unless red termination bars or red side row bars are visible.

The statement is true because it pertains to the safety protocols in aviation during an approach to landing. When flying in conditions with approach lighting systems in use, pilots must maintain an altitude of at least 100 feet above the threshold elevation until they have positive visual identification of the runway environment, specifically the red termination bars or red side row bars. These visual cues indicate that the pilot is safely aligned with the runway and that they can proceed without jeopardizing safety.

The requirement to not descend below this altitude without visual confirmation is crucial in ensuring that pilots do not unintentionally continue an approach or landing under conditions where visibility may be compromised, which could lead to potentially unsafe situations.

Other choices may suggest scenarios where this requirement is either not applicable or could be disregarded. However, the standard practice is consistent across various conditions to enhance safety during landing approaches. Thus, adhering to this protocol helps prevent accidents and ensures a safer landing environment.
