S/L direct bac. PC assist. IAD

[dropzonefool 0]

HI, was wondering which method gets a canopy faster over a student.

Been a static line I for 2 years now (PC assist). Been jumping a C182, I have has to "short line" a student before. ( do not release the slack in the static line, firm grip, to open container before a student with bad body position can flip out of control. Will a direct bag or IAD achieve this faster? opions?
Thank you

I think the fastest way is direct bag. DB is probably also best with an unstable student because they can't grab the static line, and it gets the canopy in the air quickly. With that said, the cleanest deployments with a standard piggyback rig and square main seem to be with IAD. I've done both as the jumper and instructor. IAD wins as the most comfortable deployment, static line direct bag wins as the most secure. Try the different methods yourself in both the student and instructor positions.

Agreed.

I have worked with all three systems and canopies ranging from T-10s to Mantas.
PC assist is my least favorite as it ives students the most time to flip, grab PCs, etc.

Direct bag....no question....also safer if the student goes unstable......nothing to grab, tangle/horseshoe as far as a pilot chute goes....

Thanks guys, Forgive me for my inexperience, I have noticed the new proficiency cards for S/L I to now include Direct bag rigging. I didn't have to back when I went through the program.

Question: Can a static line with a flex pin used in PC assist, be converted to Direct bag? Basically am I to understand that the Direct bag is attached to the S/L and sorta releases the canopy like the modern free bag on a reserve? I learned with PC assist and have no experience with Direct bag other than watching old war movies where Military jumpers bomb the door and you can see the bag trailing the plane connected to the S/L. Note, I will not make any mods to our existing system nor will I conduct a Direct bag jump prior to training, just asking generically.
Thank you

Correct

However, when you convert, be sure to invite a grumpy old Master Rigger and a grizzled old Jumpmaster as there are some subtleties that are not apparent until after you rip the tail off an airplane or two.
The other option is to order new direct bags from the factory that sewed your containers.

Thanks man, don't wanna rip a tail off. It is the only plane we have! HA!

If you think about it:
1) pilotchute assist has the length of the static-line and then the pilot chute and bridle prior to the bag lifting off of the student's back.
2) IAD eliminates the static-line, but still has the pilot chute and bridle length.
3) Direct bag has the static-line length, but it leads directly to the bag, hence eliminating the pilot chute and bridle length.

Tom is right about the opening aspects of direct bag versus IAD.

Another advantage of the IAD is the capability to have your student rigs set up the same way for all of the types of skydives that your student is doing, IAD, freefall or AFF as long as you are using BOC. This eliminates possible rigging errors and makes equipment checks identical for all types of students.
Also, if you are going with direct bag, I understand that line twists are common unless you make some changes to the line stowage.

i have done a few thousand dispaches with s/l direct bag seen perfect exits end up with twists, seen nice pack jobs end up with twists and seen some real crapy's with no twists.
twists happen when the d bag flicks as the lines are being un stowed, i dont know of any way to stop it from happening, its just the disadvantage of the system.

sorry for jumping in and highjacking your thread.
