What should be done to the flare cartridge after every flight?

The correct approach to handling the flare cartridge after every flight is to rotate it in a shift down approach. This practice is vital for ensuring the operational readiness and safety of the flare cartridge for future use.

Rotating the flare cartridge allows for the even distribution of wear and helps to identify any potential issues with the device. It ensures that the cartridge is properly seated and capable of functioning when needed. This step is crucial in maintaining the reliability of emergency signaling equipment, which can be essential for safety in various operational contexts.

In contrast, other options do not prioritize the necessary checks and maintenance actions needed for such equipment. Simply disposing of the flare cartridge immediately does not take into account the ongoing requirements for safety and operational readiness. Performing a full inspection and repair after every flight might be too resource-intensive without a careful assessment of wear, and reinstalling it without checks undermines the fundamental safety protocols necessary for effective emergency responses.
