* The trolley receiving bar was removed at dawn.
* The airmen started the aircraft and warmed up the engine at intervals.
* The pilot climbed into the aircraft when enemy aircraft were reported.
* The ship hoisted the [[International maritime signal flags|international flag code F]] when the decision was made to launch. (CAM ships were usually stationed at the head of the outboard port column of a convoy so they could manoeuvre into the wind for launch.)
* An airman removed the pins, showed them to the pilot, and took them to the Catapult Duty Officer (CDO).
* The pilot applied 30 degree flaps and {{Frac|1|3}} right rudder.
* The CDO raised a blue flag above his head to inform the ship's master of his readiness to launch.
* The ship's master manoeuvred the ship into the wind and raised a blue flag above his head to authorise the launch. (The ship's master stood on the starboard [[bridge wing]] to avoid the catapult rocket blast which sometimes damaged the [[Port and starboard|port]] side of the bridge.)
* The CDO waved his blue flag indicating he was ready to launch upon a signal from the pilot.
* The pilot opened full throttle, tightened the throttle friction nut, pressed his head back into the head-rest, pressed his right elbow tightly against his hip, and lowered his left hand as a signal to launch.
* The CDO counted to three, waited for the bow to rise from the trough of a swell, and moved the switch to fire the catapult rockets.<ref name="proceedings"/>
