What is the correct sequence for pulling and installing pins in the cockpit?

The correct sequence for pulling and installing pins in the cockpit is to pull the seat pin first, followed by the canopy pin. This sequence is critical for ensuring safety during egress and operations.

Pulling the seat pin first allows the pilot or aircrew member to safely detach the seat from its restraints before accessing the canopy. If the canopy pin were to be pulled first, there could be a risk of inadvertently engaging the ejection mechanism or having limited access to the cockpit, hindering a safe exit.

This sequential approach prioritizes the safety and operational integrity of the aircraft, making it an essential procedure that crew members must adhere to in order to ensure an effective and safe egress process.
