FADS III TEST

Question 1

What does the acronym FADS stand for?

Answer 1

Fly Away Dive System

Question 2

List all the reliefs and their set points for the CAOS racks and FADS III.

Answer 2

FADS III: CCA components include two automatic overpressure relief valves set to relieve at 300 psig

CAOS Racks: Reliefs lift at 5500 psig

Question 3

What is the air in stowage in each CAOS flask rack when fully pressurized?

Answer 3

868 SCF per rack (3 flasks)

Question 4

What does the acronym CAOS stand for?

Answer 4

Chamber Air and Oxygen Supply (SNDLRCS Tech Manual page 1-4)

And

Compressed Air and Oxygen System (Dive Manual page 18-4)

Question 5

What are the wet/dry charging rates for air and O2?

Answer 5

AIR:
200 psi/min (dry)
400 psi/min (wet)

OXYGEN:
100 psi/min (dry)
200 psi/min (wet)

Question 6

How many and what size air filters are there in the FADS III? Where are they located?

Answer 6

There are two 10 micron in-line filters (both designated F-020) located inside the CCA; one is on the A Supply side and the other is on the B Supply side.

Question 7

Why do we switch between A supply and B supply on odd/even diving days?

Answer 7

The intended purpose is to not cause more wear on a individual supply, but rather wear the supplies evenly. Primarily the regulators.

Question 8

Explain step by step how to properly install and torque a deck hose to the back of the FADS III.

Answer 8

• Remove designated port cap and hose plug; check for damaged threads.
• Connect hose to CCA port- tighten fitting finger tight and then tighten wrench tight not to exceed 1/8 turn or 72 in-lbs.
• Connect strain relief.

Question 9

Utilizing KM-37 with EGS, what is the maximum depth for SSD with our current configuration?

Answer 9

190 fsw

Question 10

What are the pneumofathometer corrections for finding Max Depth?

Answer 10

0-100 fsw (+ 1)
101-200 fsw (+ 2)
201-300 fsw (+ 4)
301-400 fsw (+ 7)

Question 11

What are the pneumofathometer corrections for finding Max Depth?

Answer 11

0-100 fsw (+ 1)
101-200 fsw (+ 2)
201-300 fsw (+ 4)
301-400 fsw (+ 7)

Question 12

What is the “quick” way to find manifold pressure for a MK-20 SSD to 30 fsw? Show work.

Answer 12

Divide the depth by 2 and at 90

30 ÷ 2 = 15, 15 + 90 = 105 MMP

Question 13

What is the “quick” way to find manifold pressure for a MK-20 SSD to 30 fsw? Show work.

Answer 13

Divide the depth by 2 and at 90

30 ÷ 2 = 15, 15 + 90 = 105 MMP

Question 14

What is the floodable volume of one CAOS flask?

Answer 14

.935³ft

Question 15

What is the FADSIII max operating pressure?

Answer 15

250 psi
