ARM EXTENSION
(OPTIONAL)
Once the drogue is deployed, tap the student’s head or shoulder to indicate it is time for him to put his arms out in
normal freefall position. DO NOT reach around and pull the students arms into position, as this would give the
student a chance to grab your arms. Another recommended technique is to grab the student’s elbows and push
them up and away from their body, this will usually cause them to release their grip on the main lift web.
DROGUE RELEASE
The drogue may be released at any time during “drogue fall.” To release the drogue (thus deploying the main
canopy), simply pull the drogue release handle located at the bottom left-hand corner of the main container and on
the right front strap. A pull of approximately 3-4 inches will release the drogue or the secondary drogue release
situated on your right upper legstrap.
When you pull the drogue release handle, you will feel an immediate trap door effect. Meaning you will accelerate
momentarily until the main canopy starts to inflate. The now partially collapsed drogue acts as a pilot chute and pulls
your canopy to line stretch in about half a second. The canopy will streamer for a second or two and then open slowly.
(If you pull the release handle completely and do not feel this sensation, your drogue has failed
to release.)
This is a critical time for awareness. If anything major goes wrong, a bag lock or streamer, your speed will pickup
quickly. Maintain altitude awareness and exercise emergency procedures promptly.
