When is it appropriate to confirm the installation of chocks?

Confirming the installation of chocks is a critical safety procedure that ensures the aircraft remains stationary and secure while on the ramp. This step is particularly important during flight preparations, as it helps to prevent any accidental movement of the aircraft, which could lead to serious accidents or injuries.

Before engaging in any ground operations, including loading or fueling, it is essential to verify that the chocks are properly placed. This confirmation acts as a safety net, ensuring that the aircraft will not roll or move unintentionally when personnel are working around it. Performing this check during flight preparations is therefore the most logical and effective time to confirm that chocks have been installed correctly, as it helps establish a safe environment for all subsequent activities on the ramp.
