What does a CLEF check involve?

A CLEF check is specifically focused on the pre-spin, stall, or aerobatics check, which is essential for ensuring that the aircraft is prepared for maneuvers that involve these flight conditions. This type of check is critical for safety, as it verifies that the aircraft is functioning correctly under conditions that can lead to stall situations or require specific handling techniques during aerobatics.

In this context, the pre-spin and stall checks ensure that pilots are aware of the aircraft’s behavior and characteristics before entering maneuvers where stalling might occur and can help mitigate risks associated with spins. Conducting this check is an integral part of preparing for flight, especially for training and operational scenarios where such maneuvers are expected.

While the other choices involve important aspects of aircraft inspection and readiness, they do not specifically address the unique considerations of performing maneuvers that involve spin and stall characteristics.
