Which information must a pilot log when entering simulated instrument conditions?

When a pilot enters simulated instrument conditions, it is crucial to log specific details that directly pertain to the instrument training being conducted. Logging the location and type of instrument approach completed is essential because it provides a clear record of the pilot's practical experience and proficiency under simulated instrument conditions. This information is critical for both training purposes and compliance with regulatory requirements.

Logging the location helps document where the training was conducted, allowing for the evaluation of various environmental and procedural factors specific to that location. Additionally, specifying the type of instrument approach completed (such as ILS, VOR, RNAV, etc.) records the pilot’s exposure to and practice with different navigation systems and standards, which are vital for developing instrument flying skills.

The other details mentioned, such as aircraft type and destination, date and flight altitude, or flight plan and weather conditions, while important in the broader context of flight operations, do not specifically reflect the requirements for logging simulated instrument conditions, making them less relevant in this particular scenario.
