Chapter 2
DEPLOYMENT TYPES
There are currently six different types of deployment
methods.
TYPE 1: CANOPY FIRST DEPLOYMENT
With this method, the lines are stowed vertically or
horizontally in the container. Examples of this method
are the T-7A chest pack or the B-12 back parachute.
[Figure 2-19]
TYPE 2: TWO-STOW DIAPER OR HALF
DIAPER
This method utilizes split line groups. Two stows from
one line group lock the diaper, compensated by offsetting
stows of the other line group in the container with the
remainder of the lines stowed in the container. Examples of this method are the early Strong 26' Lo-Po and the
Pioneer “K” series reserves. [Figure 2-20]
TYPE 3: ASCUITTO OR PIGLET-STYLE FLAT
DIAPER
This deployment features a full diaper with all lines
stowed left to right or perpendicular to the radial seam.
Examples of this method are the Piglet, Phantom, and
Security Aero Conical (SAC) canopies. [Figure 2-21]
TYPE 4: HANDBURY OR PRESERVE FULL
DIAPER
This features a choker-type diaper which wraps around
the canopy skirt. It is locked with three stows and all lines
are stowed on the diaper parallel to the radial seam.
Examples of this method are the Preserve series canopies,
Strong Lo-Po Lite, and the Hobbit square reserve. [Figure
2-22] The military quarter bag is basically a version of
the Type 4 method.
