PADI Dive Planning and Management 3

Question 1

What is the recommended minimum amount of air reserve a diver should have when ending a dive?

Accepted Answer

1,000 psi (70 bar)

Answer

PADI recommends ending dives with at least 500 psi (35 bar) as a minimum, but 1,000 psi (70 bar) is widely considered the industry-standard safe reserve.

Question 2

A diver planning to fly after diving should wait a minimum of how long after a single no-decompression dive?

Accepted Answer

12 hours

Answer

PADI guidelines recommend waiting at least 12 hours after a single no-decompression dive before flying to allow adequate nitrogen off-gassing.

Question 3

Which planning tool accounts for altitude dives by adjusting no-decompression limits?

Accepted Answer

PADI Wheel or dive computers set for altitude

Answer

The PADI Wheel (or altitude-capable dive computers) incorporates altitude adjustments because reduced ambient pressure at altitude changes decompression calculations.

Question 4

What is a 'dive brief' and when should it occur?

Accepted Answer

A pre-dive orientation covering site, hazards, procedures, and signals given before entering the water

Answer

A dive brief is a pre-dive meeting where the dive leader covers site conditions, entry/exit, hazards, hand signals, and emergency procedures before the group enters the water.

Question 5

When planning a drift dive, what is the most critical logistical element to arrange in advance?

Accepted Answer

A reliable surface support boat or tender to follow divers

Answer

A surface support boat that tracks and retrieves divers is essential for drift dives because divers may surface far from the entry point.
