satisfactory, the launching officer depresses the
fire button. If, after coming to full power on the
catapult, the pilot desires to stop the launch, he
or she does so by shaking the head negatively,
rather than by giving the "thumbs down"
signal. At the same time, the pilot transmits
"suspend, suspend." At night, the visual signal
also consists of not turning on the navigation
lights. The catapult safety observer signals
suspend to the launching officer in the ICCS,
using standard hand or wand signals.

Loads launches may also be required for post
maintenance catapult checkout.
NO-Loads tests shall be conducted under the
supervision of a qualified launching officer. To
prevent injury to personnel, safety lines shall
be rigged along the deck inboard of the catapult
and safety personnel shall be stationed in the
catwalk to keep unauthorized personnel clear
of the catapult area.
