PADI Dive Planning and Management 2

Question 1

When planning a multi-level dive, which sequence of depth profiles is safest to follow?

Accepted Answer

Deepest portion first, then progressively shallower

Answer

PADI recommends the 'reverse profile' warning: you should dive deepest first and ascend progressively shallower to allow nitrogen off-gassing and reduce DCS risk.

Question 2

What is the primary purpose of a pre-dive safety check (BWRAF)?

Accepted Answer

To verify equipment is correctly configured and functioning before entering the water

Answer

BWRAF (BCD, Weights, Releases, Air, Final OK) ensures all equipment is properly set up and working before the dive begins.

Question 3

A dive group is planning a shore dive at an unfamiliar site. What is the FIRST step in site assessment?

Accepted Answer

Check local dive charts, guidebooks, or consult local dive operators

Answer

Researching the site through charts, local knowledge, and dive operator briefings is the essential first step before entering an unfamiliar dive site.

Question 4

Which factor most directly determines the maximum allowable bottom time on a repetitive dive?

Accepted Answer

Residual nitrogen from previous dives

Answer

Residual nitrogen carried from previous dives reduces the allowable bottom time on subsequent dives to avoid exceeding no-decompression limits.

Question 5

What does the term 'surface interval' refer to in dive planning?

Accepted Answer

The rest period between dives that allows nitrogen to off-gas

Answer

A surface interval is the time spent on the surface between dives, during which the body off-gases residual nitrogen, affecting repetitive dive limits.
