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

    Answer: 1,000 psi (70 bar)

    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.

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

    Answer: 12 hours

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

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

    Answer: PADI Wheel or dive computers set for altitude

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

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

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

    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.

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

    Answer: A reliable surface support boat or tender to follow divers

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

  6. Which condition is a contraindication that should cause a diver to cancel a planned dive?

    Answer: Recent respiratory illness or congestion

    Respiratory congestion can prevent equalization of ears and sinuses and may worsen at depth, making it a medical contraindication for diving.

  7. The 'rule of thirds' for air management is most commonly applied to which type of diving?

    Answer: Overhead environment diving such as caverns and caves

    The rule of thirds (one-third in, one-third out, one-third reserve) is standard air management for overhead environments where direct ascent is not possible.
